Find Your Next TypeScript Project

We are seeking an expert senior backend engineer to develop a REST API using Node/TypeScript. The role involves implementing JWT+RBAC for authentication and authorization, integrating Stripe for subscriptions, and setting up a billing engine. Additionally, the engineer will work with QuickBooks and DocuSign for financial and document management, and integrate with MLS API for real estate data. The ideal candidate will have strong experience in API integration and backend development.

• Walk me through how you would implement role-based access control (RBAC) for a SaaS platform with 4 user roles (Admin, Broker, Client, Public). How do you prevent a broker from accessing admin-only routes?
• Describe the most complex Stripe integration you've built. Specifically: have you implemented Stripe Connect for payouts, and how did you handle webhook idempotency?
• A user reports that they can see another user's listing data. Walk me through how you would debug this and what security layers should have prevented it.
• How would you design a billing engine that auto-invoices brokers for 60/40 commission splits on closing fees, with monthly statements and QuickBooks sync?
• Share a link to a public API you've built (or redacted OpenAPI docs). What's one decision you'd change about that API if you rebuilt it today?

A short note on your availability

**Project overview**

We run a B2B electronics repair business. We have two internal tools that need to work together:

- **ZR** : our repair management CRM (Vue 2/3 + JavaScript + Element Plus, Laravel backend)
- **CS** : a stock and commission management tool (Vue 3 + TypeScript + Vite + Pinia, Laravel 11 backend)

CS was partially built then abandoned. It is currently not in use at all. We need someone to pick it up, read the existing code carefully, and deliver specific missing features without rewriting what already works. You will work under the supervision of our technical lead who reviews and approves every milestone before payment is released.

---

**Phase 1 — UI restructuring (entry task, $150 fixed)**

This is the only deliverable to start. Phase 2 is conditional on Phase 1 being approved by our technical lead.

Restructure the Item view in the CS frontend. No backend or database changes required. All fields already exist. The work is purely about renaming labels and reorganising the display layout across three existing files : `LotDetailView.vue`, `BatchItemsView.vue`, `AIPhotoView.vue`.

Current labels : OEM, Commercial Ref, MPN, Unit.

Target labels and layout :

- Section "Item description" : Brand, SPN OEM's manual, PN from sticker, SN board, Rev. software, Rev. hardware
- Section "eBay description" : Category, Condition, Price
- Section "Pictures" : existing photo gallery

The challenge is distinguishing display labels (to rename) from internal variable names (to leave untouched) in files of 1 200 to 1 600 lines of TypeScript. This is a reading and precision task, not a build-from-scratch task.

**Deadline : 5 days. Budget : $150.**

---

**Phase 2 — Item entity + CS-ZR link (if Phase 1 approved, $600)**

Two deliverables :

**2a — Item entity in CS ($200)**

Create the Item as a first-class entity in CS. Currently it does not exist as such. This requires a Laravel migration, an Eloquent model, a REST endpoint, and a simplified creation flow in the Vue 3 frontend : when a single card enters stock, the user creates a Batch containing one Item directly, without having to go through the Sub-lot layer explicitly.

**2b — CS-ZR bidirectional link ($400)**

Implement the two operational flows :

Flow 1 from ZR : in the ZR repair sheet, allow creating a new CS Item or selecting an existing one, then attach the Repair to that Item. The existing `crossSales.js` service and `PATCH /repairs/ (id)/cs-unit` endpoint must be reused as the foundation.

Flow 2 from CS : in CS, after creating an Item, allow deciding whether the card needs repair before sale. If yes, trigger Repair creation in ZR via the existing `POST /proxy/repairs` proxy. If no, proceed directly to the sale flow.

---

**Stack**

| Layer | Tech |
|---|---|
| CS frontend | Vue 3, TypeScript strict, Vite, Pinia |
| CS backend | Laravel 11, Sanctum, REST API |
| ZR frontend | Vue 2/3, JavaScript, Element Plus |
| Inter-app | REST API, Sanctum token, existing crossSales.js |

---

**Code standards — mandatory**

- TypeScript strict throughout CS frontend — no implicit `any`
- Composition API only in Vue 3 components — no Options API
- All API calls through the configured axios client — no native fetch
- Explicit error handling on every API call (success, 404, network error)
- No `console.log` left in production
- You are fully responsible for all code delivered, including AI-generated code — you must be able to explain every line during the onboarding call

---

**Organisation**

- Technical lead reviews and approves every milestone on staging before payment is released
- GitHub Issues : primary channel for all tasks and questions — one issue per feature
- Discord : video calls only (onboarding call mandatory before start, milestone reviews)
- Dedicated working branch only — merge to dev via pull request approved by technical lead
- No subcontracting — you work alone
- Upwork screenshot tracking mandatory on all billed hours

---

**Code sample required before any contract**

Before we move forward with any candidate, we ask for a small code sample matching our exact stack constraints. This replaces references we cannot verify.

**Produce two files :**

`useItem.ts` (composable)
- TypeScript strict
- Composition API only
- Uses axios via a pre-configured client instance — not native fetch
- Exposes : `item` (typed ref), `loading` (ref\ boolean\ ), `error` (ref\ string | null\ ), `fetchItem(id: number)`
- `fetchItem()` handles explicitly : success, 404 with a specific message, and network error
- Define an `Item` interface with at minimum : `id`, `brand`, `spn`, `serial_number`, `status`

`ItemCard.vue` (component)
- Receives an `item` prop typed with the `Item` interface above
- Displays Brand, SPN, Serial Number, Status with a colored badge based on status value
- Emits a `select` event with the item id on click
- Tailwind classes only — no inline styles
- TypeScript strict on props and emits

---

**How to apply**

Your proposal must include :

1. One example of a past mission where you worked on an **existing** Vue 3 + TypeScript codebase — not a personal project built from scratch. What it was, what you modified, how you read the code before touching it.
2. Your approach to picking up an abandoned codebase — concretely, what do you do first ?
3. Your availability over the next 30 days.

**Proposals without these 3 points and without the code sample will not be reviewed.**

Overview
I am building SearchDesk — an AI-powered executive search platform for boutique recruiting firms and solo executive recruiters. Think of it as a complete replacement for the combination of LinkedIn Recruiter, an ATS, a client CRM, and an AI writing tool — built specifically for the way boutique search professionals work.

An MVP has been prototyped in Lovable (React + TypeScript + Supabase). I need an experienced full-stack developer to take that prototype to a production-ready, commercially deployable product.

This is a collaborative engagement. I own the product vision, feature specs, and business direction. You own the technical execution — architecture decisions, code quality, deployment, and performance. I will tell you what to build and why. You will tell me the best way to build it.

What the Platform Does
SearchDesk gives executive recruiters:

• A candidate database for managing their proprietary talent pool
• A seven-stage search pipeline (Kanban) per active search
• A client CRM for tracking companies, contacts, and placements
• Gmail and Outlook sync — emails auto-logged to candidate and client profiles
• Calendar integration — interview scheduling from inside the platform
• AI screening call notes — recruiter records a call, AI transcribes and writes the candidate assessment
• AI candidate pitch documents — polished client-ready summaries generated in 15 seconds
• AI resume tailoring — upload a resume and job description, AI rewrites the resume for the role
• AI passive outreach drafts — personalized LinkedIn and email messages to candidates
• AI search brief generator — paste a JD, AI builds the full brief and ideal candidate profile
• AI market intelligence briefings — monthly sector briefings the recruiter sends to clients
• Business development monitor — watches target company careers pages for senior postings
• Candidate trajectory tracker — resurfaces placed executives 18 months after placement
• Revenue and source-of-hire analytics
• Referred candidate intake forms — private intake links per search
• Compensation benchmarking — AI salary range estimates per role

The AI layer runs entirely on the Anthropic Claude API. This is non-negotiable — Claude API experience is required.

What "Production-Ready" Means for This Project
The Lovable prototype demonstrates the concept and core flows. Moving to production means:

• 1. Clean, maintainable codebase
Not generated code. Proper component structure, typed interfaces, clear separation of concerns. Code a developer can read and extend six months from now.
• 2. Robust Supabase backend
Proper RLS policies, Edge Functions for all AI and third-party API calls, database migrations tracked and versioned, no API keys in the frontend.
• 3. Third-party integrations that actually work
Gmail OAuth (Google Identity), Outlook OAuth (Microsoft Graph API), Google Calendar, Outlook Calendar, OpenAI Whisper for audio transcription, Stripe for billing.
• 4. Performance at scale
The platform needs to handle a full candidate database of 500–2,000 records, multiple concurrent searches, and AI generation without hanging or timing out.
• 5. Error handling and resilience
Graceful failures, meaningful error messages, retry logic on API calls, no silent breakages.
• 6. Deployment pipeline
The platform needs to be live on a custom domain with CI/CD, not just running locally or in a preview environment.

Tech Stack
The MVP was built on React + TypeScript + Tailwind + Supabase. I am open to recommendations on the best production stack for this type of product. If you have strong opinions about a different frontend framework, hosting architecture, or approach to Edge Functions, make the case and I will listen.

What cannot change: Supabase as the database and auth layer, and the Anthropic Claude API for all AI features. Everything else is negotiable.

Specific Technical Requirements
Frontend
• React or Next.js (your recommendation)
• TypeScript throughout
• Tailwind CSS
• Drag-and-drop Kanban for the search pipeline
• File upload handling (PDF and DOCX parsing for resumes and job descriptions)
• Browser audio recording (MediaRecorder API) for the screening call feature
• Real-time UI updates via Supabase Realtime subscriptions
• Mobile-responsive layout

Backend (Supabase)
• Full RLS policy implementation on all tables
• Edge Functions for: Claude API calls, Gmail/Outlook sync, Whisper transcription, Stripe webhooks, daily cron jobs (BD monitor, trajectory tracker reminders)
• Secure OAuth token storage and refresh for Gmail and Outlook
• Supabase Storage for audio files and uploaded documents
• Database migrations versioned and documented

Third-Party Integrations
• Google OAuth (Gmail + Calendar)
• Microsoft Graph API (Outlook + Outlook Calendar)
• OpenAI Whisper API (audio transcription — $0.006/minute)
• Stripe (subscription billing — Solo $349/month, Team $249/seat, Agency $1,500/month)
• Resend or SendGrid (transactional email for reminders and notifications)

AI — Anthropic Claude API
• Claude Sonnet for: candidate summaries, pitch documents, progress reports, resume tailoring, outreach drafts, search brief generation, market intelligence briefings, screening call assessments
• Claude Haiku for: candidate matching scores, trajectory outreach drafts, BD pitch drafts, compensation estimates
• All Claude calls server-side via Supabase Edge Functions — no API key in the client

Scope of Work
This is a fixed-price project broken into milestones. I expect us to define the milestones together after reviewing the Lovable prototype and full feature specs. Rough milestone structure — open to your input:

Milestone 1 — Foundation and Core Flows
Clean codebase setup, auth, database schema with full RLS, candidate database, search pipeline Kanban, client CRM. Essentially: the platform works without AI.
Milestone 2 — AI Feature Layer
All Claude API integrations: search brief generator, candidate matching, pitch documents, progress reports, outreach drafts, resume tailoring, comp benchmarking, market intelligence.
Milestone 3 — Third-Party Integrations
Gmail OAuth + sync, Outlook OAuth + sync, Google Calendar, Outlook Calendar, screening call recording + Whisper transcription.
Milestone 4 — Automation and Analytics
BD opportunity monitor (daily cron), candidate trajectory tracker (18-month resurface logic), smart reminders (stale alerts), source-of-hire analytics, revenue tracker.
Milestone 5 — Billing, Deployment, and Polish
Stripe subscription integration, custom domain deployment, CI/CD pipeline, performance optimization, error handling audit, documentation handoff.

Budget
Fixed price: under $10,000 for the full project.

I understand this is competitive pricing. In exchange I am offering: a well-specified product (full feature docs, Lovable prototype, detailed prompts for every feature), a collaborative working style (I will not throw vague requirements over a wall), and the potential for an ongoing relationship if the initial build goes well. I am not looking for the cheapest developer — I am looking for the most value at this price point from someone who can deliver clean, production-grade work.

If your experience and rate are above this range but you are genuinely interested in this type of product, make the case in your proposal. I will consider it.

What I Am Looking For
Must Have
• 3+ years of full-stack development experience
• Strong React and TypeScript — not just "familiar with"
• Supabase experience — Row Level Security, Edge Functions, Realtime, Storage
• Anthropic Claude API experience — you have built production features with it, not just played with the playground
• OAuth integrations — Google or Microsoft Graph, ideally both
• Experience taking an AI-assisted prototype to a production-grade codebase
• English fluency — written communication will be frequent and needs to be clear
• Located in the US, UK, Canada, or Australia

Strong Plus
• Experience with Stripe subscription billing
• OpenAI Whisper or other audio transcription experience
• Prior work on SaaS products for professional services — recruiting, consulting, legal, finance
• Experience with file parsing (PDF, DOCX extraction)

Not a Fit If
• You have never shipped a production Claude API integration
• You only work from detailed wireframes and cannot make any UI decisions independently
• You are not comfortable pushing back when a technical approach will not work
• Your Upwork profile has no reviews or portfolio relevant to this type of work

How to Apply
I will screen all proposals and move forward in three stages:

Stage 1 — Proposal Review
Tell me in plain English: what in this spec concerns you most, what would you do differently, and what similar projects have you shipped. Link to relevant portfolio items. No cover letter templates — I read every word and I will notice.
Stage 2 — Technical Test
I will send a small, paid test task to the shortlist. Likely: take a specific feature from the spec, write the Supabase schema and Edge Function for it, and show me how you would structure the React component. Should take 2–3 hours. I will pay $100 for completed test tasks regardless of whether I hire you.
Stage 3 — Video Interview
30-minute call with the final two or three candidates. I want to hear how you think about technical problems, not just see that you can write code.

Timeline
I need someone to start within 2–4 weeks. The Lovable prototype will be finalized before we begin. Full feature specifications, database schema, and Edge Function specs are documented and ready to hand over at project start.

One Last Thing
This platform is genuinely useful to the people it is built for. Executive recruiters who use it well will close more searches, spend less time on administrative work, and build a more defensible business. If that kind of product appeals to you — if you care about what you are building, not just that you are building something — that is the kind of developer I want to work with.

To apply: Send your proposal, portfolio links (specifically anything involving Claude API, Supabase Edge Functions, or OAuth integrations), and your honest assessment of the scope and timeline based on what you have read here.

We are seeking an experienced developer proficient in React, TypeScript, and Node.js to implement changes on our existing website. The ideal candidate will have a strong understanding of front-end and back-end development, with the ability to optimize and enhance user experience. You will be responsible for making modifications based on specific requirements, ensuring high-quality code, and collaborating with our team. If you have a passion for building robust web applications and can deliver results promptly, we’d love to hear from you.

Our Backend is fully written in Python and the other Code is combinination of TypeScript, Python and JavaScript.
Separately, both codes work perfectly, but together we haven't been able to integrate the code for the coin data and charts etc. into our site.

Hello, I have a developed electron programme for my browser game. There are puzzles in game and I have a trained AI model but when puzzle showed up my programme couldn't solve I couldn't find problem every time it solves incorrectly. Do you have expertise in this area?

1. Project Overview
ClearZone is a cleaning compliance SaaS platform built for cleaning contractors and their clients. It replaces paper checklists, manual timesheets, and phone calls with a single guided digital system — giving operatives clarity on the job and giving clients verifiable proof that the work was done.

This document is the full product brief for the custom build of ClearZone. It covers every module, every role, the complete data model, integration requirements, and commercial terms expected of the development engagement. It supersedes any earlier specification and should be treated as the single source of truth.

1.1 The Four Products
ClearZone is made up of four interconnected products:

Product User Purpose
Operative App (PWA) Cleaning operative Clock in, complete zone checklists, take photos, log chemicals, report issues, manage profile
Ops Dashboard Ops manager / supervisor Live site overview, scheduling, timesheet approval, alerts, reporting, staff management
Client Portal Facilities manager / client Read-only view of compliance data, zone status, photo evidence, SLA reports
Stock Management Ops manager + operative Track consumable stock levels, set par levels, receive low-stock alerts, raise purchase orders

1.2 What Already Exists
A working visual prototype has been built in Lovable (a no-code platform) to demonstrate the product concept. This prototype is for demonstration purposes only — it runs on hardcoded demo data with no backend. The custom build described in this brief starts from scratch using the technology stack defined in Section 3.

Key principle
The operative app is the foundation. Everything else — the dashboard, client portal, and agent intelligence layer — depends on the data the operative app collects. Build quality and reliability here is non-negotiable.

 
2. Gaps in the Existing Specification
The previously shared Operative App Technical Specification (Version 1.0, April 2026) covers the operative PWA in strong detail. However, the following areas are either absent or insufficiently specified and must be addressed in the build:

2.1 Ops Dashboard — Not Specified
The existing spec references a 'management console' briefly but does not specify it. The Ops Dashboard is a full web application requiring its own detailed design. Key screens required:
• Live site overview — all sites, real-time zone status per operative, alert feed
• Operative location tracking — based on last QR code scanned
• Timesheet review and approval workflow
• Zone and task template builder — create/edit zones, assign task checklists per zone
• QR code generation and print-ready PDF export
• Staff scheduling and shift assignment
• Direct messaging to operatives and bulletin broadcast
• Chemical library and COSHH management
• Credential and training management — verify uploads, track expiry, set site requirements
• Site induction builder and completion tracking
• Reporting — SLA performance, zone completion rates, issue resolution, compliance summary

2.2 Client Portal — Not Specified
The spec mentions the client portal only as a Phase 3 item without any detail. The Client Portal is a separate read-only web interface for the end client (facilities manager). Required screens:
• Live zone status view — which zones are complete, in progress, or outstanding
• Photo evidence feed — timestamped and geotagged completion photos per zone
• SLA performance dashboard — daily, weekly, monthly compliance metrics
• Issue report log — all flagged issues with status and resolution notes
• Daily PDF report access — downloadable compliance reports per site
• Notifications — alerts when SLA thresholds are breached

2.3 Stock Management Module — Not Specified
The existing spec does not mention stock management. This is a required module, detailed fully in Section 5 of this brief.

2.4 Authentication and Role-Based Access — Underspecified
The spec does not define the authentication system or role hierarchy. This must be built explicitly:
• Authentication via Supabase Auth (email/password + magic link)
• Four distinct roles: Operative, Supervisor, Ops Manager, Client
• Row-level security enforced at the database level — not just frontend routing
• Operatives can only see their own shifts, assigned zones, and their own profile
• Supervisors can see all operatives at their assigned sites
• Ops Managers have full access across all sites in their company account
• Clients have read-only access scoped to their contracted sites only

2.5 Multi-Tenancy — Not Specified
ClearZone is a SaaS product serving multiple cleaning companies. The data model must support multi-tenancy from day one:
• Each cleaning company is a separate 'Organisation' with isolated data
• Operatives, sites, zones, and clients belong to an Organisation
• No data leakage between organisations at any layer
• Organisation-level settings: branding, language defaults, notification preferences

2.6 Pricing and Subscription — Not Specified
ClearZone has three pricing tiers (Starter £49/site/month, Professional £89/site/month, Enterprise £149/site/month). The system must enforce feature gating based on the active subscription tier:
• Starter: up to 3 sites, up to 20 zones per site, core app + dashboard + daily report email, CSV payroll export
• Professional: unlimited sites and zones, client portal, 10+ languages, UK payroll integrations, lone worker safety, SLA reporting
• Enterprise: white-label branding, multi-client management, advanced analytics, offline mode, dedicated account manager, API access
• Subscription managed via Stripe — billing, upgrades, downgrades, and cancellation

2.7 Payroll Integrations — Underspecified
The spec lists payroll integrations as a Phase 3 item but does not define the scope. The following integrations must be specified and built:
• Xero — approved timesheet data exported as draft invoices or payroll items
• Sage Payroll — CSV or API export in Sage-compatible format
• BrightPay — CSV export in BrightPay import format
• Generic CSV export — fallback for all other systems
• Each export must handle: operative name, site, clock-in/out times, total hours, break deductions, pay rate (if configured), approval status

2.8 IP Ownership and Code Repository — Not Specified
The following must be agreed before work commences:
• All intellectual property created in this engagement belongs solely to ClearZone Ltd
• The codebase must be hosted in a GitHub repository owned by ClearZone Ltd from day one
• The developer must not retain any copy of the codebase on project conclusion
• All third-party libraries used must be permissively licensed (MIT, Apache 2.0, or equivalent)

 
3. Technology Stack
The following stack is specified in the existing operative app spec and is confirmed as the target stack for all ClearZone products:

Component Technology Applies To Notes
Frontend framework Next.js (React) + TypeScript All products Single monorepo preferred
Styling Tailwind CSS All products Utility-first, responsive by default
Operative offline storage IndexedDB via Dexie.js Operative PWA Full offline shift capability required

4. Operative App (PWA)
The operative app is a Progressive Web App that runs on any device with a browser. It is the primary data collection tool. All design decisions prioritise accessibility, offline capability, and simplicity for non-technical, multilingual users.

4.1 Core User Journey
• Arrive at site → Clock In (GPS geofence or QR fallback)
• View assigned zones for the shift
• Scan QR code at each zone to start work
• Complete task checklist (mandatory tasks enforced)
• Log chemicals used
• Take mandatory completion photo (timestamped, geotagged)
• Flag any issues with photo and description
• Move to next zone
• Clock Out at end of shift — summary shown, timesheet auto-submitted

4.2 Screens Required
Screen Key Elements Notes
Clock In Large button, GPS check, QR fallback, green tick animation on success Vibration feedback on mobile
Zone List Zones in order, colour status (grey/blue/green), progress bar Pull-to-refresh, offline works identically
Zone Active (Checklist) QR scan to enter, task list with large tick boxes, chemical log, photo capture, issue flag button Cannot skip required tasks
Messages Direct messages + Bulletins tabs, text/voice send, push notifications Offline queue for outbound messages
My Hours Read-only timesheet — shifts, hours, approval status No editing capability
My Profile Personal details, document upload (ID, DBS, certs), expiry alerts, language selector Guided first-time setup flow
Clock Out Summary (zones done, issues flagged, total hours), confirm button GPS or QR location check
Stock (Operative) Simple list of products at this site, stepper to update current volume Read/update only — no order management

4.3 Languages at Launch
Minimum 10 languages: English, Polish, Romanian, Portuguese, Spanish, Bengali, Urdu, Hindi, Arabic, Somali. Each language is a JSON translation file — additional languages must be addable without code changes.

4.4 Offline Capability
Hard requirement
The operative app must function with zero internet connectivity for an entire shift. This is a hard requirement, not a nice-to-have.

• On last connectivity before shift: app downloads all zones, checklists, chemical lists, and language pack for the day
• All operative actions (clock-in, QR scans, task ticks, photos, issue flags) write to IndexedDB
• Background sync queue processes in order when connectivity returns
• Retry with exponential backoff on sync failure
• Photos queue behind text data and upload progressively
• Operative sees green/grey connectivity indicator only — no error messages, no functionality difference

4.5 Lone Worker Safety
• Activates automatically when only one operative is clocked in at a site
• Periodic check-in prompt every 15 minutes (configurable) — single tap to confirm
• Missed check-in triggers immediate alert to supervisor with last known location
• Escalation to secondary contact if supervisor does not acknowledge within 5 minutes

 
5. Ops Dashboard
The Ops Dashboard is a web application for cleaning company operators and site managers. It is the control centre that sits above the operative app — taking the data operatives generate and turning it into actionable management information.

5.1 Screens Required
Screen Key Elements Notes
Home / Overview All active sites, zone completion %, live operative count, alert feed, overdue zones highlighted Real-time updates via websocket or polling
Site Detail Zone-by-zone status for one site, operative locations (last QR), time since last activity Drill down from Overview
Operative Management All operatives list, status (active/inactive), credential status, site assignments Search and filter
Scheduling Assign operatives to sites and shifts, set zone order, handle ad-hoc requests Dispatch urgent task to nearest available operative
Timesheet Review All pending timesheets, approve/query per shift, flag discrepancies Approved timesheets feed payroll export
Zone Builder Create/edit zones, assign tasks, set required vs optional, set chemical list per zone, generate QR codes Print-ready PDF of all QR codes per site
Task Library Global library of task templates reusable across zones
Chemical Library COSHH-compliant product list with hazard symbols, approved list per site
Staff Profiles View operative profile, verify credential uploads, set required credentials per site, training expiry alerts Manual upload capability for in-house training records
Site Inductions Build induction content per site, track completion by operative, block clock-in until complete
Messaging All operative message threads, bulletin creation and broadcast, read receipts Urgent flag for safety alerts
Reports SLA performance, zone completion rates, issue resolution times, chemical usage, training compliance Export to PDF and CSV
Settings Organisation profile, site management, subscription and billing, notification preferences, language defaults

5.2 Payroll Export
From the Timesheet Review screen, approved timesheets can be exported in the following formats:
• Xero — API push or CSV in Xero payroll import format
• Sage Payroll — CSV in Sage-compatible format
• BrightPay — CSV in BrightPay import format
• Generic CSV — configurable column mapping for all other systems

5.3 Daily Report Email
Each morning, an automated PDF report is generated per site and emailed to the nominated client contact. The report must include:
• All zones cleaned the previous day — time started, time completed, operative name
• Completion photo for each zone
• Chemical log per zone
• Any issues flagged with photos and current status
• SLA compliance summary (percentage of zones completed on schedule)
• Hours summary per operative
The report is branded with the cleaning company logo (Professional and Enterprise tiers). It is sent automatically — no manual action required.

 
6. Client Portal
The Client Portal is a separate, read-only web interface for facilities managers and building clients. It gives clients transparent, real-time visibility of cleaning compliance at their sites without access to operational or HR data.

6.1 Access
• Clients access via a unique login (email + magic link — no password to manage)
• Each client sees only the sites they are contracted for
• No access to operative personal details, payroll data, or internal management information

6.2 Screens Required
Screen Key Elements Notes
Site Dashboard Live zone status for each site — complete, in progress, outstanding. Operative count currently on site. Refreshes in near real-time
Zone Detail All tasks completed for a zone, completion photo, chemical log, operative name, timestamps Photo lightbox view
Issue Log All issues flagged at this client's sites, with photos, status, and resolution notes Filter by site, status, date
SLA Reports Daily, weekly, monthly compliance metrics — percentage complete, average completion time, trend charts Export to PDF
Daily Reports Archive of all daily PDF reports for this client's sites — downloadable
Notifications Email alert when SLA threshold is breached or a critical issue is flagged Configurable threshold per client

 
7. Stock Management Module
The Stock Management module tracks cleaning consumables (toilet rolls, hand soap, bin bags, cleaning fluid, etc.) per site. It alerts when stock falls below acceptable levels and enables purchase orders to be raised directly within the platform.

7.1 Data Model
Entity Key Fields Notes
Product id, name, category, unit (rolls/litres/bags/each), description Global product library, managed by Ops Manager
SiteStock siteId, productId, currentVolume, parLevel, lastUpdatedBy, lastUpdatedAt One record per product per site
StockOrder id, siteId, productId, quantityOrdered, status, raisedBy, raisedAt, deliveredAt, notes Status: Draft → Submitted → Ordered → Delivered
StockAlert id, siteId, productId, alertType (Low/Critical), triggeredAt, resolvedAt, resolvedBy Auto-generated when volume drops below par

7.2 Alert Logic
• Low alert: current volume falls below par level — item flagged 🟡 Low
• Critical alert: current volume falls below 25% of par level — item flagged 🔴 Critical
• Alert displayed in Ops Dashboard alert feed and stock overview
• Email notification sent to Ops Manager on Critical alert
• Alert resolves automatically when operative updates volume above par level

7.3 Ops Manager Screens
Screen Key Elements Notes
Stock Overview (/stock) All products across all sites, current volume, par level, status badge (OK/Low/Critical), last updated, Raise Order button per low item Filter by site, category, status
Site Stock Detail (/stock/[site-id]) Site-specific product list, inline editable current volume, visual progress bar (current vs par), last updated by/when Audit trail of all volume updates

Product Library (/stock/products) Create/edit products, set categories and units Ops Manager only
Par Level Settings Set and edit par levels per product per site Ops Manager only — operatives cannot change par levels

7.4 Operative Stock Screen
• Simple scrollable list of products assigned to operative's current site
• Current volume shown with status colour indicator
• Stepper control (+/-) to update current volume after restocking
• Confirmation tap saves update with timestamp and operative name
• No access to par level settings, order management, or product library

10. Commercial Terms Required
The following terms must be agreed and documented in a signed contract before development commences. This section is not a legal document — it is a list of requirements that must be reflected in the formal agreement.

10.1 IP and Code Ownership
• All intellectual property developed during this engagement belongs solely to ClearZone Ltd from the moment it is created
• The GitHub repository must be created under and remain under a ClearZone Ltd-owned account
• The developer retains no rights to use, resell, or reference the codebase or product
• All third-party libraries must be permissively licensed (MIT, Apache 2.0, ISC or equivalent)

10.2 Pricing and Payment
• Quote must be broken down by phase — a single lump sum is not acceptable
• Fixed price per phase preferred; if time-and-materials, a cap must be agreed per phase
• Payment schedule tied to phase delivery milestones, not calendar dates
• No payment in advance for undelivered phases

10.3 Timeline and Overruns
• Start date, phase end dates, and final delivery date must be agreed in writing
• What happens if a phase overruns must be defined — does cost increase? Does timeline extend?
• ClearZone must have the right to pause or terminate at the end of any phase

10.4 Handover and Documentation
• On completion, all code must be documented to a standard that allows another developer to continue work
• All environment variables, third-party API keys, and infrastructure access must be handed over
• A deployment runbook must be provided — how to deploy, how to roll back, how to scale
• A 30-day post-launch support period must be included for bug fixes arising from the build (not new features)

E-Commerce & Integrations Engineer — NeonO

NeonO is a Canadian salon management SaaS (React/TypeScript, Supabase, Stripe Connect, Vercel) with a multi-tenant storefront builder, themeable salon-branded shops, and a dropship pipeline that fulfills orders through a national beauty distributor (Metro Beauty). We're hiring a dedicated engineer to own the end-to-end e-commerce surface: the visual storefront builder, the themes system, the outbound/inbound IBM integration to our distributor, and the final hardening of our three-way dropship revenue split (Metro / Salon / NeonO). You'll be the single point of accountability for everything a salon owner touches when launching and running their online store, and for every byte that crosses the wire to the distributor.

You'll own the storefront builder wizard and theme architecture (catalog, product detail, cart, checkout, brand theming) — shipping polish, responsive fixes, and new merchandising primitives — while keeping all themes visually and behaviorally consistent. On the integrations side, you'll harden our SFTP pipeline to Metro's IBM iSeries (inventory sync, order drops, shipment confirmations, returns), build reconcilers that catch drift between our order table and Metro's acknowledgements, and finalize the dropship checkout so that Stripe application fees, on-behalf-of charges, and the post-charge three-way transfer split (Metro 55 / Salon 35 / NeonO 10) are atomic, idempotent, and auditable. Expect to work closely with our payments and webhooks code (Stripe Connect, settlement ledger, revenue-split snapshots) since the dropship flow touches all of it.

We're looking for 4+ years of production React/TypeScript, real experience with Stripe Connect or an equivalent marketplace-payments platform, and comfort with Postgres/Supabase, edge functions (Deno), SFTP and CSV/fixed-width batch ETL, and webhook-driven reconciliation. Bonus points for previous e-commerce storefront work, prior integration experience with IBM iSeries / AS400 / legacy EDI-style feeds, or Canadian tax/compliance familiarity (GST/HST/PST, PIPEDA, CASL). You should be someone who reads an unfamiliar edge function end-to-end before changing it, treats money code as adversarial, and is comfortable owning a domain rather than waiting to be assigned tickets. This is a high-autonomy role reporting directly to the founder, with a clear mandate and a demo on the horizon.

We do not reply to emails for this role off platform and will be ingored.

• Describe your recent experience with similar projects

We’re looking to build a set of approximately 3 Power Apps that integrate with our existing SharePoint environment. The goal is to streamline some internal processes, specifically:
- Timesheet tracking and submission
- Basic project management (task tracking, status updates, possibly dashboards)
- Vacation/leave request and approval workflow
We’d like the apps to be user-friendly, scalable, and properly connected to SharePoint lists/libraries, with appropriate permissions and automation (Power Automate flows where needed).
At this stage, I’m looking to understand:
- Your experience with Power Apps + SharePoint integrations
- A rough estimate of timeline and pricing for the full scope
If this sounds like a good fit, I’d be happy to share more details and discuss next steps.
Looking forward to hearing from you.
Best,
Manal Nehme

About Us
We are a Salesforce Summit Partner building a 100% Salesforce-native enterprise platform. Our customers include Fortune 500 companies across hospitality, agriculture, financial services, and more. We're scaling aggressively and looking to double the size of our development team with experienced, committed developers who want to build something meaningful — not just clock hours on a contract.
We've had developers from our early days who have been with us for 8+ years. That's the kind of relationship we're looking for — someone who treats this as a home, not a gig.

The Role
We're hiring a Senior Backend Developer who is equally strong in Node.js/TypeScript and Salesforce Apex. You'll build and maintain the backend services, API integrations, and Salesforce-side business logic that power a mature, complex enterprise product used by some of the largest companies in the world. This is not basic Salesforce configuration or simple API wrappers — this is deep backend engineering with real scalability and governor limit challenges.

Required Skills
Salesforce Backend:

Salesforce Apex — triggers, batch Apex, queueable Apex, scheduled jobs, platform events
Governor limit optimization and bulk-safe design patterns
Salesforce Metadata API and/or Tooling API
SOQL and SOSL — complex queries, relationship queries, aggregate queries
Callout patterns — async callouts, named credentials, integration architecture

Node.js / Backend:

Node.js with TypeScript (not just JavaScript — TypeScript is required)
SQL — complex queries, joins, aggregations, indexing strategies, query optimization
RESTful API design, versioning, and error handling
Authentication and authorization patterns (OAuth 2.0, JWT, session management)
Asynchronous programming patterns (promises, async/await, queues, event-driven architecture)

General:

Git-based version control workflows
Experience working on a SaaS product (not just client project work)
Understanding of CI/CD concepts and deployment pipelines
Database design and data modeling
Strong debugging, logging, and monitoring practices


What We're Looking For

8+ years of professional backend development experience, with meaningful depth in both Salesforce Apex and Node.js/TypeScript
Product company experience — you've built and maintained a product backend, not just delivered one-off client projects
Managed package or AppExchange experience is a strong plus — if you've worked within namespace constraints and packaging limitations, you understand our world
Long-term mindset — we want someone who will grow with us for 3+ years. Share your longest client engagement and why it lasted
Ownership mentality — you take accountability, think independently, and care about the quality of what ships
Economical rates that reflect strong value for deep expertise — we pay fairly for the right talent and reward long-term commitment.

• Write a short Node.js (TypeScript) function that authenticates with Salesforce using OAuth 2.0 and retrieves metadata using the Metadata API or Tooling API. Explain your approach to handling token refresh and error handling.
• Describe a production bug that was your fault. Name the technology, root cause, what you did in the first 60 minutes, and what you changed in your process afterward. Be specific.
• What's the hardest problem you solved using both Salesforce (Apex/Metadata API) and Node.js/TypeScript? What constraint did you hit, what did you try first that failed, and what worked?
• How do you use AI tools (ChatGPT, Copilot, Claude) in your daily work? What do you use it for, what never, and how do you verify output? Give one example where it helped and one where it misled you.
• You're 18 months into a project. The codebase is messy, deadlines are tight, and a new dev writes code in a totally different style. What do you do and what conversations do you start?
