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
Service worker / sync Workbox Operative PWA Background sync queue for offline data
QR scanning html5-qrcode Operative PWA Browser-native, no plugins
Push notifications Web Push API + Firebase Cloud Messaging Operative PWA Works when app is not open
State management Zustand All products Persisted to IndexedDB on operative
Internationalisation next-intl Operative PWA 10+ languages at launch
Database PostgreSQL via Prisma ORM Backend With row-level security via Supabase
Authentication Supabase Auth All products Email/password + magic link
File storage Cloudflare R2 or AWS S3 All products Photos, documents, PDFs
Backend hosting Railway or Vercel Backend + frontend Auto-deploy from GitHub
Payments Stripe SaaS billing Subscriptions, upgrades, cancellation
Email Resend or SendGrid All products Daily reports, notifications, alerts

 
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

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)

This project centres on building a fully-featured social casino app that runs smoothly on both iOS and Android from a single codebase. The first release will focus on an engaging Slots experience, but the architecture should leave room for additional games later.

Core gameplay
• Slots engine with authentic reel physics, configurable pay-tables, free-spin bonuses and daily coin drops.

Social & progression layer
• Personal user profiles, including avatar, coin balance and level progress that persist across devices.
• Global and friends-only leaderboards that refresh in near real-time so players can compare wins and bragging rights.
• Cloud-saved data to keep every spin, purchase and achievement in sync.

Monetisation
• Native in-app purchases for coin packs and special offers, wired to the Apple and Google billing APIs with secure receipt validation.
• Simple offer management panel so I can schedule discounts without pushing a new build.

Admin & analytics
• A lightweight backend (Firebase, PlayFab, or similar) to handle authentication, coin economy, leaderboards and basic analytics. If you favour another proven stack, outline why and I’ll consider it.

Deliverables
1. Production-ready iOS and Android builds uploaded to TestFlight / Internal Testing.
2. Source code with clear documentation.
3. Deployment guide covering backend setup, store listing assets and necessary certificates.
4. Two-week post-launch support window for critical fixes.

Acceptance criteria
• App installs and launches on current iOS and Android flagship devices with <5 s cold start.
• No crashes after 5,000 automated spins.
• All purchases complete successfully in sandbox and live environments.
• Leaderboard positions update within 30 seconds of a qualifying win.

Timeline is flexible enough for quality polish, yet I’d like a realistic milestone plan before we start. Ready to dive in once we agree on tech stack and schedule.

Skills: Mobile App Development, iPhone, Android, Unity 3D, iOS Development, Android App Development, Unity, PlayFab

We're building a health and fitness app that uses AI to act as a personal coach, not just logging workouts or counting calories, but actually adapting to the user over time based on their habits, goals, and history. Think less "fitness tracker" and more "coach in your pocket."

The app needs to feel alive. When a user hasn't logged anything in three days, it should notice. When they hit a goal, it reacts. The AI layer is the core of the product, not an add-on.

We have Figma designs ready and will share full specifications after a short NDA. The designs cover all core screens and the component library is already defined, so you won't be designing from scratch, your focus will be implementation.
Main deliverables for this contract:

Flutter app for iOS and Android (single codebase)
AI integration for personalized coaching responses (OpenAI or similar)

User onboarding flow with goal setup
Dashboard with habit tracking and AI feedback loop
Push notifications for streaks, reminders, and coaching nudges

Additional screens, backend architecture details, and the full feature list will be shared privately after the NDA is signed. We're keeping the public post high level intentionally.

A few things that matter to us:
We're not looking for someone to assemble a template. The AI coaching logic, how it reads user context and generates relevant, non-generic responses, needs real thought. If you've integrated LLM APIs into a mobile app before and hit the edge cases (token limits, response latency, fallback handling), you'll know what we mean.

Firebase is the likely backend, but we're open to a short discussion on that. We'd rather hear your reasoning than have someone just agree with whatever we suggest.

To apply: Tell us about a Flutter app you've shipped that involved AI or behavioral features. A Play Store or App Store link is more useful than a description. If you've handled push notification logic tied to user behavior (not just scheduled reminders), mention that too.

NDA required before full brief is shared. Payment verified. Serious inquiries only.

* Bet system (red/green/blue)
* Auto result generation (Firebase Cloud Functions)

We're IKI Health — an early-stage healthcare platform built in Europe, scaling toward the US market. We combine patient monitoring, clinical nutrition, and personalised wellness into one ecosystem. Small team, real mission, room to grow.

We're not looking for someone to execute a ticket list. We're looking for a person — curious, proactive, and genuinely excited about being part of something early-stage where their work actually shapes the product.

--- WHO WE'RE LOOKING FOR ---

Mindset first:

• Proactive — you don't wait to be told what's next. You spot things, ask, suggest.
• Flexible — priorities shift in a startup. You see that as opportunity, not chaos.
• Hungry to grow — you want to get better, learn from the team, take on more over time.
• Ownership mentality — when something is yours, you care about it properly.
• Clear communicator — async-first team. You update without being asked, flag blockers early.

And genuinely curious about AI — not because it's trendy, but because you can see how it changes what's possible in a product like ours. We already have AI-generated videos in the platform; we want someone who gets excited about where that goes next.

--- THE ROLE ---

Part-time (10–15h/week), long-term, fully remote. You'll work across our stack:

• React (TanStack Start, TypeScript, Tailwind CSS) — our web applications
• Flutter / Dart — our mobile app and web dashboard
• Node.js / MongoDB / Firebase — our backend and data layer
• AI integrations — we're actively using AI-generated video (Kling/Runway) and plan to expand

You don't need to be expert in all of these on day one. We need solid React or Flutter as a base, genuine curiosity about the rest, and the attitude to learn what you don't know yet.

--- WHAT WE OFFER IN RETURN ---

• Real ownership over what you build
• A team that values your input and gives honest feedback
• Room to grow: as IKI scales toward the US, scope and responsibility grow too — potential full incorporation
• Exposure to an evolving AI toolchain in a real product context
• A product that matters — built with nutritionists, backed by clinical evidence

--- SKILLS ---

Required:
• React (hooks, TypeScript) OR Flutter/Dart — 3+ years in either
• Node.js / REST APIs — solid understanding
• MongoDB or Firebase / Supabase — hands-on experience
• Git / GitHub — daily use

Nice to have:
• Both React and Flutter
• Experience integrating AI APIs or generative media tools
• Tailwind CSS, TanStack, Cloudflare Workers
• Interest in healthtech or consumer wellness

--- RATE EXPECTATIONS ---

Junior-to-mid profiles (3–5 years), competitive hourly rates. Early-stage startup — honest about that. The trade-off is real ownership, stability, and growth upside as IKI scales toward the US.

I’m building an enterprise-grade, multi-tenant SaaS tool that spans the full stack: a Next.js front-end, an Express (or .NET Core if you prefer) API layer, and cloud-native services on AWS and Azure. The immediate focus is threefold—polished UI, robust back-end logic, and tight cloud integration—so I need each piece advancing in parallel.

Front-end
The app centres on interactive dashboards, client-onboarding forms, and a role-based user-management interface. Everything should load fast, feel responsive, and remain easily themeable for different tenants.

Back-end & Multi-Tenancy
We’ll expose REST/GraphQL endpoints, route traffic through a proxy layer, and isolate tenant data cleanly. Firebase handles file storage and console-driven operations, while the core data lives in the cloud provider best suited to each environment. Also use of the caching to maintain fast access to the client.

Cloud & Security
AWS and Azure services—think S3, DynamoDB, Lambda, RDS, or their Azure counterparts—must be wired through infrastructure-as-code. API keys and other secrets stay in Secrets Manager, Azure Key Vault, or a comparable vault so nothing sensitive ever lands in source control.

Payments
Stripe, PayPal, and RazorPay need to be fully integrated with clean, reusable modules that respect each gateway’s webhook flow and support subscription, one-off, and trial logic.

Deliverables
• Responsive Next.js front-end with dashboards, onboarding, and user admin
• Express/.NET Core API with complete tenancy separation
• Cloud infrastructure scripts (AWS & Azure) plus Firebase storage hooks
• Secure secret-management implementation
• Payment modules for Stripe, PayPal, RazorPay with end-to-end test coverage
• Deployment documentation and a short hand-off walk-through
* caching tools, like redis or firebase caching.

I’m ready to move quickly and iterate in milestones, validating each feature against staging tenants as we go.

Developer should know firebase rules, payment gateways, react js and expert in cloud technologies, and should have experience building SAAS tools and security standards for storing data. Should also have a creative mind to design the app beautifully and considering user's POV.
This is enterprise level app, need to sign NDA and provide 6+ months support after deployment to production. Developer should know how to use the Cloud tools like Gemini, Anthropic etc.

Skills: Azure, Node.js, Google Cloud Storage, Payment Gateway Integration, Full Stack Development, Google Firebase, .NET Core, Next.js, SaaS, Gemini

Project Description:
I am looking for a professional Python developer to optimize and secure an existing Telegram Reward Bot. The bot is built using pyTelegramBotAPI (Telebot), Flask, and Firebase Real-time Database.
The core structure (511 lines of code) is already functional. I do NOT need a bot from scratch. I only need an expert to fix 5 specific logic gaps to ensure the bot acts with "AI-level precision" and prevents any user fraud.
Key Deliverables (The Fixes):
Strict Input Validation (Regex): Secure the Wallet Binding system. The bot must reject any text that doesn't strictly match the required format (Name, Acc Type, 11-digit Number for PKR / 34-char 'T' prefix for TRX).
Withdrawal Logic Hardening: Fix the "Withdraw Funds" button. It must perform real-time balance checks against Firebase and only accept integer inputs that meet minimum thresholds (PKR 2,000 / TRX 12,000).
Referral Milestone Condition: Modify the referral reward system. The 150-coin reward should ONLY be credited to the inviter AFTER the new referral completes at least 3 tasks (tracked via tasks_count in Firebase).
Admin Control Extension: Add /deductcoins [user_id] [amount] and /banuser [user_id] commands to the existing admin panel.
Auto-Reminder Scheduler: Optimize the current reminder thread to ensure it sends a 24-hour inactivity reminder accurately based on the user's last task time.
Navigation Flow: Fix the "Back Button" logic to ensure the menu never disappears if a user types an invalid command.
Technical Requirements:
Expert in Python & Firebase RTDB.
Strong understanding of Input Sanitization and State Handling.
Ability to work within the existing 511-line codebase without deleting or breaking current functions.
Budget: Fixed $20 - $40.
Timeline: 1-2 Days.
Note: I have the source code ready. Place your bid only if you can work within this budget. Generic $100 to $150+ bids will be ignored.

Skills: Python, Database Administration, Debugging, Flask, Security, Google Firebase, Automation, API Development, Telegram API, Bot Development
