Streamline API Projects with Vollna

About Akerio. Akerio is a UK-based applied AI company. We build platforms that turn messy enterprise data into scored, auditable recommendations: the next diesel price for one of Europe's largest independent fuel distributors, a risk flag on a tenant across 41 shopping centres, a credit score a bank's committee can trace back to the source record. Our models are built by a PhD team from Stanford and the University of Chicago, every output shows what drove it and how confident it is, and the platform runs on-premise or in the cloud. We are live in production across energy, commercial real estate and financial services, with 18 AI modules running in one deployment alone. We are a small team shipping to demanding enterprise clients, so the work you do reaches production and gets used.
• Job: Full time
• Job type: Remote

The role
Our retail property analytics platform, live across 41 shopping centres, runs on a set of NestJS microservices: a core business service, an AI service that calls LLM tools, a notification service, and a Python compute service that serves forecasts and risk scores. Every month Airflow retrains and reruns revenue, footfall, tenant risk and mall performance models, and the backend has to get those results to the screen fast and correctly. You join the team that builds and runs these services. You will write production code from your first month, with a senior reviewer on every pull request.
What you will work on
• NestJS endpoints for leasing, finance, visitor and budget modules: DTOs, validation, permissions, and the SQL behind them.
• PostgreSQL and PostGIS: schema changes, migrations, query tuning, statement timeouts on heavy reports.
• Service-to-service work over gRPC and Kafka, Redis caching, and real-time updates over Socket.IO.
• Endpoints that Airflow calls to run forecasts and write back results and accuracy metrics.
• The AI service: tool definitions the LLM can call, MCP integration, caching AI commentary, logging every conversation to Langfuse.
• Python FastAPI work in the compute service when a model needs a new input or output.
• Production hygiene: health endpoints, log rotation, monitoring alerts, dependency and security upgrades flagged by Trivy.

How we build Jira, spec-first work with AI coding tools (Claude Code), code review on every PR
Your first six months
• First month: environment running, first fix merged in week one, then one endpoint shipped with tests.
• Month three: you own a module's backend (for example finance or budget) and its test suite.
• Month six: you take a feature from spec to production with light review and handle its production issues.
What you bring
Junior (0 to 2 years):
• A computer science or engineering degree, or equivalent proof that you can build software.
• TypeScript or JavaScript you have used on something real: an internship, a serious side project, open source. Node.js is a big plus.
• SQL beyond SELECT: joins, indexes, transactions.
• Git, the command line, and the habit of reading the docs before asking.
Mid (2 to 4 years):
• Production backend experience in Node.js and TypeScript, ideally NestJS.
• You have designed REST APIs and PostgreSQL schemas other people built on, and written migrations that ran on live data.
• Testing as a habit: unit and integration tests with Jest or similar.
• Docker, CI pipelines, and you have debugged a service in a deployed environment.
Both levels: clear written English, curiosity about how the data is used, and comfort with AI coding tools while still owning every line you merge. Turkish is a plus.
Nice to have
• Python and FastAPI.
• Kafka, gRPC, Redis or any event-driven microservice work.
• PostGIS or other geospatial data.
• Exposure to LLM APIs, tool calling or MCP.
• Azure, Linux server administration or monitoring setup.

We are a small team shipping to demanding enterprise clients, so the work you do reaches production and gets used.

• Job: Full time
• Job type: Remote

The role
Our largest deployment, a retail property analytics platform, is live across 41 shopping centres. Asset managers, leasing and finance teams open it to see footfall, turnover forecasts, tenant risk and NOI, then ask the built-in AI assistant why a number moved. Behind it sit 49 dashboard widgets, 53 AI tools, a set of NestJS microservices and a Python compute service. You take features across that whole path: the React screen, the NestJS endpoint, the Postgres query, and the AI commentary that explains the result. You will also talk to the people using it, because most of our backlog comes straight from their feedback.

What you will work on
• Dashboard widgets for leasing, finance and visitor analytics: time-series charts, forecast versus actual, filters that live in the URL so a view can be shared.
• The customizable home dashboard: drag, resize and save widget layouts per user.
• NestJS microservices: core business APIs, notifications, and the AI service that runs LLM tool calls and talks to our tools over MCP.
• Data endpoints over PostgreSQL and PostGIS, with SQL migrations you write and own.
• Wiring Python forecasting and risk models (FastAPI compute service, scheduled by Airflow) into the product.
• AI features in the UI: chat, quick summaries and per-widget AI commentary, cached in Redis and generated in the user's language.
• Production quality: health checks, logging, dependency upgrades, and closing security findings before they become incidents.

Our stack

Frontend: React, TypeScript, Vite, MUI, Tailwind, shadcn/ui, Zustand, React Router, ApexCharts, React Grid Layout, i18n (Turkish and English)

Backend: Node.js, NestJS microservices in a Yarn workspace monorepo, gRPC, Kafka, Redis, OpenSearch, Socket.IO

Data: PostgreSQL 17 with PostGIS, SQL migrations
Compute and ML Python, FastAPI, Airflow for scheduled forecast and scoring runs

AI: Anthropic Claude via API, tool calling and MCP, RAG over client data, Langfuse for monitoring conversations and quality

Infra: Azure, Docker and Docker Compose, nginx, Jenkins, Bitbucket, OpenTelemetry and Jaeger, Trivy; Kubernetes (Rancher) on the roadmap

How we build: Jira, Figma, spec-first work with AI coding tools (Claude Code), code review on every PR
You need to be strong in TypeScript on both sides. The rest you can pick up here.

Your first six months
• First month: local setup running, first pull request merged in week one, one widget or endpoint shipped to production.
• Month three: you own one product area end to end (for example finance analytics) from Figma to production.
• Month six: you shape API and frontend standards across services and pair with juniors on their first features.

What you bring
• 4+ years building production web applications, with real depth in TypeScript, React and Node.js.
• NestJS or a similar structured Node framework, REST API design, and PostgreSQL schema and query work.
• You have shipped data-heavy UIs: charts, big tables, filters, exports, and you know how to keep them fast.
• Docker, CI pipelines and debugging in a deployed environment, not only on localhost.
• You write tests and care about code that the next person can read.
• Clear written English. Turkish is a plus: most of our current users work in Turkish.
Nice to have
• Python and FastAPI, enough to read and extend a compute endpoint.
• Microservice plumbing: Kafka, gRPC, Redis caching, tracing.
• You have built a UI on top of LLM output: streaming, citations, tool calls, human review.
• Experience with real estate, retail, energy or finance products.

How we work
Small team, short feedback loops. Client feedback lands in Jira every week, we write the spec before the code, and every pull request gets a review. We use AI coding tools as standard and still expect you to own every line you merge.

Hiring process
1. 30-minute intro call.
2. 30-minute session: present your case to the CPO and an engineer.
3. 15-minute call with a founder.

What we offer

Seeking an AI Workflow Builder / Agent Engineer to design and prototype automation for faculty teaching and research workflows. This fixed-price discovery and prototype project may lead to ongoing build and support work. Please propose a fixed price for Phase 1, with emphasis on demonstrated capability, architecture, and clear scope rather than the lowest hourly rate.

Job post: AI Workflow Builder for Faculty Teaching and Research System
Title:
AI Workflow Builder / Agent Engineer for Teaching-Deck, Case-Vignette, and Academic Research Automation
Engagement:
Fixed-price discovery and prototype project, with the possibility of an ongoing build and support relationship.
Budget:
Please propose a fixed price for Phase 1. I expect to hire based on demonstrated capability, architecture, and a clear scope—not the lowest hourly rate.

I am a business-school faculty member seeking an experienced AI workflow builder to create a private, reusable AI system that automates several recurring faculty workflows.

This is not a request for graphic design, slide design, generic virtual-assistant work, or a basic chatbot. I know what high-quality teaching materials should look like and will provide the templates, examples, standards, feedback, and final judgment.

I need someone who can turn my existing materials, preferences, documents, and repeatable processes into a reliable AI-enabled workflow system. The system should use my prior work as a knowledge base, preserve my voice and standards, produce editable deliverables, and keep me in control through approval steps before anything is finalized. The goal is to reduce the time required to move from raw source material to a high-quality first draft—not to eliminate faculty judgment.
Primary objectives
Build a private AI workflow system that can support the following four functions:
1. Teaching deck automation
• Ingest publisher PowerPoint files, chapter objectives, syllabi, assigned readings, my existing decks, notes, and teaching preferences.
• Produce an editable first-draft teaching deck in my established format and sequence.
• Identify concepts that need explanation, classroom prompts, activities, examples, discussion questions, and instructor notes.
• Preserve the distinction between student-facing slides and instructor-only content.
• Export or generate editable PowerPoint and Word materials.
2. Teaching-vignette and case automation
• Convert my notes, professional experiences, real events, and publicly available information into well-structured teaching vignettes.
• Generate a concise student-facing vignette, a decision point, discussion questions, and a separate teaching note.
• Ensure that student and instructor materials use the same underlying facts; instructor materials may add facilitation guidance but must not contradict the student version.
• Support disguise-case treatment where appropriate, use distinct company names, and avoid invented claims, generic scenarios, repetitive language, or unsupported facts.
• Create classroom-ready materials now while retaining a structured master record that can later be developed into a publishable teaching case.
3. Instructor-guide automation
• Generate concise instructor guides linked to chapter concepts and learning objectives.
• Include recommended timing, discussion flow, anticipated student responses, deeper follow-up probes, likely misconceptions, and suggested faculty teaching moves.
• Keep materials useful in live teaching—not overly long, generic, or merely descriptive.
4. Academic research and publication support
• Organize my personal experience notes, research questions, literature, public data, and approved private materials into a secure project workspace.
• Support literature discovery, research memos, annotated bibliographies, theory maps, source matrices, study-design memos, manuscript outlines, and citation-supported draft sections.
• Maintain source provenance and distinguish clearly among: my original ideas, verified sources, public evidence, and AI-generated draft language.
• Do not fabricate citations, evidence, quotations, interview data, results, or references.
• Support scholarly workflows without attempting unauthorized academic ghostwriting.
Required capabilities
Applicants should be able to demonstrate real experience with most of the following:
• Building AI agents or multi-step workflows using leading LLM APIs or hosted AI platforms.
• Retrieval-augmented generation (RAG), document ingestion, embeddings/vector search, metadata, and source-grounded output.
• PowerPoint, Word, PDF, and spreadsheet ingestion and export workflows.
• Document parsing, chunking, citation/source tracking, and handling of long document collections.
• Workflow orchestration tools such as n8n, Make, Zapier, LangGraph, LangChain, LlamaIndex, or comparable tools.
• A secure architecture suitable for confidential faculty materials, unpublished research, and potentially sensitive professional experiences.
• Human-in-the-loop review gates, versioning, structured templates, and auditability.
• Clear documentation that allows the owner to manage the system after handoff.
• Strong communication with a nontechnical but sophisticated end user.
Experience with higher education, case-method teaching, instructional materials, scholarly research, consulting, or professional-services workflows is strongly preferred. However, technical capability and a demonstrated ability to understand complex document workflows matter more than graphic-design experience.
Important project requirements
The system must:
• Be private by design; no unrestricted upload of unpublished research, sensitive materials, student information, or confidential organizational information to public services.
• Include clear data-handling recommendations and options for sensitive versus non-sensitive materials.
• Require my approval before final exports or final-document status.
• Retain a source record for research-based outputs.
• Preserve reusable templates, examples, preferences, and prompt instructions.
• Allow iterative changes over time without rebuilding the entire system.
• Create editable outputs—not merely chat responses or locked PDFs.
• Avoid vendor lock-in where reasonably possible; document the architecture, credentials, workflow logic, and maintenance steps.
• Be designed first for my personal faculty workflow, but capable of being expanded later if successful.
Proposed project phases
Phase 1: Discovery and architecture
• Review representative materials: publisher slides, existing teaching decks, examples of vignettes and teaching notes, research documents, and desired output templates.
• Map the current and future workflows.
• Recommend an architecture, platforms, privacy approach, integrations, estimated ongoing costs, and implementation sequence.
• Deliver a written requirements document and clickable/process prototype.
Phase 2: Minimum viable system
Build one working end-to-end workflow, preferably:
Publisher PPT + chapter objectives + my prior materials -to- structured teaching-deck draft + instructor notes + editable export.
The workflow should use my templates and examples, include a review/approval stage, and produce a traceable output.
Phase 3: Expand workflows
Add vignette/case automation, instructor-guide automation, research workflow support, source tracking, and a reusable knowledge base.
Phase 4: Documentation and handoff
Provide administrator documentation, workflow diagrams, prompt/template library, data-handling guidance, training session, and a maintenance/support proposal.
Deliverables for the initial engagement
Please propose a fixed-price Phase 1/Phase 2 engagement that includes:
• Workflow and system architecture document.
• Privacy and data-handling recommendation.
• One working prototype workflow using representative materials.
• Editable PowerPoint and/or Word output from the prototype.
• Knowledge-base structure and recommended document taxonomy.
• Human-review and approval workflow.
• Source/citation provenance approach for research outputs.
• Clear technical documentation and implementation roadmap.
• A proposed recurring cost estimate for software, API/model usage, hosting, and optional maintenance.
What to include in your proposal
Please include:
1. A brief description of a comparable system you have personally built.
2. The technology stack you would recommend and why.
3. Your approach to privacy, document security, user access, and intellectual-property ownership.
4. Your proposed Phase 1 timeline, fixed price, assumptions, and deliverables.
5. Your estimated Phase 2 and Phase 3 costs, separated from monthly operating costs.
6. A link to an anonymized demo, Loom walkthrough, GitHub repository, architecture diagram, or case study.
7. Your experience with RAG, source-grounded output, document generation, PowerPoint/Word workflows, and AI quality assurance.
8. Confirmation that I will own the deliverables, documentation, workflow configurations, and any custom code created for this project.
9. Any questions you would need answered before finalizing scope.
Screening task
Shortlisted candidates will be asked to complete a paid scoping exercise using a small, sanitized sample of materials. The exercise will assess whether you can:
• Analyze a PowerPoint/source-material workflow.
• Recommend a practical private architecture.
• Identify risks involving source grounding, citations, version control, and confidential information.
• Show how the system would create structured, editable outputs while retaining a faculty approval step.
Not a fit
Please do not apply if your primary service is:
• Slide or graphic design.
• Social-media, marketing, or lead-generation automation.
• Generic chatbot setup without document workflows or retrieval.
• A no-code automation with no source grounding, privacy model, review controls, or documentation.
• Fully autonomous “research writing” that cannot explain its sources or distinguish evidence from draft language.
Long-term opportunity
The right builder may become a long-term partner as the system expands across multiple courses, teaching cases, faculty research projects, and potentially a broader academic-productivity platform. Initial work will be scoped tightly and evaluated on functionality, reliability, privacy, documentation, and the quality of the workflow—not visual design alone.

We're Third Republic and AI Republic, specialist Salesforce and AI recruitment firms with teams in London, New York and Denver. We're making Claude the operating system our recruitment consultants work through every day, and we've already built a lot in-house.

We want a certified Claude architect who has done this before at another organisation, and who still builds. You'll set the architecture and standards for how we use Claude across the business, then build the core of it alongside our developers.

WHAT YOU'LL DO
- Design how Claude, skills, agents and MCP servers fit together across the business
- Build the hardest parts yourself: MCP servers, multi-step agents, skills and system integrations
- Set the standards for how skills are built, tested, versioned and released
- Own access and governance, so the right people get the right capabilities
- Choose models and keep cost and quality in check
- Write specs our developers can build from, and review their work

WHAT YOU'LL BRING
- Claude Certified Architect (Professional preferred, Foundations at minimum)
- A Claude rollout across a whole organisation: licences, skills, connectors, governance and adoption
- Production agentic systems shipped with Claude Code, the Agent SDK, the API and MCP, including MCP servers you built
- Strong engineering foundations: Python or TypeScript, REST APIs, Git, hosting and monitoring
- Judgement on when a rule belongs in code rather than a prompt, and how to test agents properly
- Clear written English

NICE TO HAVE
- Recruitment, staffing or CRM experience
- Sales and outbound tooling, data enrichment or telephony APIs
- Working hours that overlap with both London and New York

THE ENGAGEMENT
Freelance contract, about 40 hours a week, remote, with a daily overlap with UK hours. We start with a paid trial project.

Please answer the screening questions in full. Proposals without answers won't be reviewed.

I want a complete, production-ready marketplace that seamlessly connects customers with professional videographers. The core flow is simple: a customer describes the event, the system automatically matches the request with nearby videographers, and the customer finalises the booking and pays online. From the videographer’s side, they should be able to review offers, accept jobs, manage their schedule, and showcase portfolio material.

To keep everything maintainable I need the build broken into the following discrete deliverables:
1. User Module – sign-up/login, event brief form, real-time matching results, secure payment and booking confirmation.
2. Videographer Module – profile & portfolio management, job alerts, accept/decline interface, calendar sync, payout tracking.
3. Admin Module – dashboards for user / job / payment oversight, dispute handling, analytics, and configurable matching rules.

We run a multi-tenant B2B SaaS built on Laravel. Multiple customer organizations share one application. We want an independent penetration test to validate that boundary and the overall app security.

Scope:
-Primary goal: multi-tenant isolation: we’ll give you logged-in accounts in two separate organizations. -Prove whether a user in Org A can read, modify, or infer any data belonging to Org B, via the UI, direct API/endpoint calls, IDOR on record IDs, forced browsing, parameter tampering, exports/downloads, etc.
-Access control & privilege: role/permission enforcement (admin vs non-admin actions), horizontal and vertical privilege escalation, authorization on every state-changing endpoint.
-Authentication & session: login, two-factor (TOTP + email), lockout/rate-limiting, session handling, password reset.
-Standard web risks (OWASP Top 10 / OWASP WSTG): injection, XSS, CSRF, SSRF, insecure file upload (CSV import), security misconfiguration, sensitive-data exposure.
-Out of scope: DoS/stress testing, physical, social engineering, and third-party infrastructure (hosting provider). No destructive actions against the environment.

What you’ll deliver:
-A formal written report following a recognized methodology (OWASP WSTG or PTES): executive summary, each finding with severity (CVSS), reproduction steps, evidence, and remediation guidance. The report should be suitable to share with prospective enterprise customers and auditors.
-One free retest after we fix the findings, to confirm closure, with an updated report.

Environment & access we provide:
-Access to the staging site (it sits behind an extra HTTP auth gate, we’ll supply those credentials plus app accounts in two organizations, including an admin and a non-admin role).
-A short rules-of-engagement doc defining scope, the testing window, and a stop/contact protocol.

To apply, please include ALL of the following (applications missing these will be declined):
1- A redacted/sanitized sample report from a past web-app pentest (or a link).
2- In 3–5 sentences, how you would specifically approach testing multi-tenant data isolation in a SaaS app.
3- Start your proposal with the word Test
4- One concrete access-control / IDOR vulnerability you’ve found in the past and how you discovered it.
5- Relevant certifications (e.g. OSCP, OSWE, GWAPT, CREST, Burp Suite Certified), helpful but not mandatory if your experience and sample report are strong.
6- Your proposal: approach/methodology, estimated effort (hours), timeline/availability.
7- Confirmation you’ll treat all findings and materials as confidential (a confidentiality clause will be in the contract) and test only the authorized staging environment.

I am launching Bharat Darshan, a large India tourism portal, and need a technical partner or volunteer WordPress developer to help build the website. The project includes 28 states and 8 union territories, temples, tourist places, festivals, travel guides, a WordPress site, admin panel, Hindi, English, and 5 foreign languages, live hotel booking API, payment gateway, weather API, Google SEO, and affiliate monetization. Budget is limited at the start, so volunteer collaboration or revenue-sharing partnership may be possible. Interested developers should share their portfolio, relevant WordPress projects, and estimated timeline. Revenue share and ownership will be finalized through a written agreement.

I need a web-based text-to-speech platform focused on one clear goal: letting users generate polished voiceovers for their videos, ads and social posts. The user flow should feel effortless. Visitors either paste their script into a text field or upload it as a document, pick the voice and language they like, fine-tune speed and pitch, choose their preferred output quality/format, then download the finished audio in seconds.

The site has to run smoothly on all modern browsers, so a clean front-end (React or similar) coupled with a solid back-end is essential. I am open to whichever cloud TTS engines or open-source models you feel give the best balance of realism, language coverage and cost efficiency; please outline your reasoning and any licensing factors when you bid.

Core deliverables
• Responsive UI/UX that handles the two input methods (paste text / upload script)
• Voice, language, speed, pitch and format selectors that update in real time
• Server-side generation of the audio plus secure, one-click download links
• Admin area where I can view usage metrics and add or remove available voices
• Deployment to my hosting of choice with clear hand-over documentation

The project is complete once a new user can land on the site, create a voiceover, download it and hear the selected settings reflected accurately in the audio. Looking forward to seeing your approach and timeline.

Skills: PHP, JavaScript, WordPress, Cloud Computing, HTML, Web Development, Audio Processing, API Development

We run a live ride-booking and transport platform at ride.smartsagor.com in Kuwait. It is a custom PHP 8.4 and MariaDB application with a working PWA. We want to turn it into two polished native apps for iOS and Android, or in Flutter (we will consider native Swift/Kotlin if you make a strong case). The new apps must match the PWA’s functionality with a much better UI and smoother performance.

The platform has 3 modules

Ride: staff ride booking and shifts
UniRide: university student transport with subscriptions and payments
B2B: corporate transport

Apps to build

1. Driver app (priority)

Secure login, with a driver role and an assigned bus/vehicle
Start and end shift or trip
Live GPS tracking sent to our API continuously, including background and screen-locked operation (foreground service on Android, background location on iOS), with battery-friendly intervals and offline queuing
Assigned trips, passenger list and pickup stops, with navigation hand-off to Google Maps or Waze
Mark passengers as picked up, dropped off or no-show
Push notifications for new assignments and changes
Clear status indicators (online/offline, GPS active, last sync)

2. Passenger app

Registration and login (phone/email, OTP if applicable)
Book rides and view upcoming and past bookings
Live bus tracking on a map with ETA (we already have an ETA calculation in our backend; the app will consume it)
Pickup points and routes, plus booking and subscription management
Payments through our existing Payzah/KNET flow (in-app webview or SDK)
Support tickets
Push notifications (bus arriving, delays, booking confirmations)
Profile and language settings

UI/UX and language

Modern, clean, professional design. We have brand guidelines (the Sagor Aura theme) and will provide colors, logo and references.
Full English and Arabic support with proper RTL layouts, switchable in-app
Light mode required; dark mode is a bonus
Smooth animations and fast, responsive maps

Backend/API

Our PHP backend is custom-built. We will provide existing endpoints and documentation.
Where endpoints are missing, we may ask you to specify the contract (REST/JSON) and our team will implement it, or you can write clean PHP endpoints if you have the skills (a plus).
Token-based auth (JWT or similar) and secure handling of location data
Push notifications through Firebase (FCM/APNs)

Deliverables

Two production-ready apps (driver and passenger), or one app with role-based login if you recommend that
Full source code in our Git repository, clean and documented
Published on Google Play and the Apple App Store (we own the developer accounts, and you handle the build and submission process)
Setup/handover documentation and a short walkthrough
30 days of bug-fix support after launch

Required skills

Strong Flutter/Dart with published apps on both stores
Proven experience with background location tracking on iOS and Android
Google Maps SDK, live markers, polylines and ETA display
Firebase Cloud Messaging, REST API integration, secure token storage
Arabic/RTL localization experience
Good English communication and regular progress updates

I'm looking for an experienced React Native developer to audit, debug, and stabilize an existing healthcare and fitness mobile app for iOS and Android. The app connects to Bluetooth-enabled exercise equipment to collect and synchronize workout data. I need someone who can investigate Bluetooth connectivity issues, data synchronization errors, app crashes, and other functional bugs. The work includes a thorough codebase audit to identify architectural weaknesses, performance bottlenecks, and potential security concerns. I also need improvements to API integrations, state management, navigation, and overall app reliability. My goal is to bring the existing application to production quality through targeted fixes, code optimization, and regression testing rather than a complete rebuild. I'm looking for a developer with strong React Native, Expo, TypeScript, Bluetooth Low Energy (BLE), and mobile debugging experience who can take ownership of the stabilization process and prepare the app for a reliable production launch.

Due to confidentiality requirements, I'll share the app and codebase once the contract is in place.

We’re looking for an experienced Frontend Developer to help us build the customer-facing side of a retail e-commerce platform.

The platform will allow customers to browse products, search and filter the catalog, add items to their cart, complete purchases, and track their orders. We also need an admin interface where our team can manage products, inventory, and orders.
We already have a clear idea of the core features and are looking for someone who can turn them into a clean, responsive, and easy-to-use interface. You’ll work closely with the backend developer to connect the frontend to APIs and make sure the main user flows work smoothly.
This is an ongoing project, so there will be opportunities to improve the existing experience and build new features as the platform grows.

What You’ll Work On

- Storefront: Build responsive pages for the homepage, product categories, product details, and promotional sections.
- Product Catalog: Implement product search, filters, sorting, product variants, pricing, and availability indicators.
- Shopping Cart & Checkout: Develop cart interactions, quantity updates, checkout forms, and order confirmation screens.
- Customer Accounts: Build login and registration flows, customer profiles, saved addresses, and order history.
- Order Tracking: Create interfaces for displaying order statuses, shipping updates, and purchase details.
- Admin Dashboard: Develop interfaces for product management, inventory updates, order processing, and basic sales reporting.
- API Integration: Connect frontend components to backend services and handle loading states, validation, and errors.
- Performance & UX: Improve page loading speed, navigation, accessibility, and the overall shopping experience across devices.

Tech Stack

The main stack includes Vue.js 3, Nuxt.js, TypeScript, and Pinia for state management. You should also be comfortable with HTML5, CSS3, modern JavaScript, REST APIs, and GraphQL, as well as Git and collaborative code review workflows.
Experience with component libraries, automated testing, and frontend performance optimization is also important.

What We’re Looking For

We’re looking for someone with 4+ years of professional frontend development experience and strong hands-on knowledge of Vue.js, TypeScript, and Nuxt.js, including server-side rendering.
You should have experience building responsive interfaces for complex web applications, working with reusable components and state management, and integrating APIs with backend services. A good understanding of authentication flows, form validation, and error handling is essential.

We also value developers who write maintainable code, can troubleshoot issues independently, and are comfortable discussing technical decisions with the rest of the team.
Experience with e-commerce websites, product catalogs, checkout flows, or admin dashboards is a strong plus.

Nice to Have

Experience with Playwright, Cypress, or Vitest would be helpful, along with familiarity with accessibility standards, SEO best practices, and frontend performance monitoring.
Experience working with design systems or Figma is also welcome.

Project Scope

The initial phase will focus on the storefront, product catalog, shopping cart, checkout, customer account pages, and core admin interfaces.
You’ll collaborate with the backend developer to integrate APIs and make sure the main customer and admin workflows are ready for production.
As the platform evolves, we expect to add new features, improve the user experience, and potentially support mobile applications through a shared API.
We’re looking for someone who can take ownership of frontend development and is interested in a longer-term collaboration.

When Applying

Please share a few frontend projects you’ve worked on, preferably in e-commerce or retail, and tell us about your experience with Vue.js, Nuxt.js, and TypeScript. We’d also like to see examples of complex interfaces or user flows you’ve built, along with your estimated timeline for the initial frontend development phase.

We’re seeking an experienced AI developer or agency to build an AI customer support system for a UK eCommerce store of our client (WordPress, 80-150 orders per day). We manage the technical side of the project and the integration; our client approves the final developer or agency, and payments.

The agent will help customers with promotions and offers, order tracking, and common pre-sale and post-sale questions, with handover to a human when needed.

The project is split into 3 phases, with the focus on the voice support agent built with Vapi, which is developed first, followed by the chat agent. Both agents must use one shared knowledge base.

The solution will rely on n8n automations and API integrations (WooCommerce, order data, knowledge base) running on our self-hosted n8n instance on a VPS.

Key requirement: every question the agent cannot answer is logged, and the client’s team can review these in one place, add the correct answer, and have both agents use it from then on, without a developer.

WHO WE’RE LOOKING FOR

Proven experience building AI voice and chat agents for real customer support
Hands-on experience with Vapi (or a comparable voice agent platform)
Strong experience with n8n automations, API and webhook integrations
Experience with UK phone number setup (nice to have)
Experience integrating with WordPress/WooCommerce via API (nice to have)
Experience building knowledge bases that non-technical staff can update (nice to have)

TIMELINE
Architecture in week 1, then 3 phases. Working Vapi voice agent pilot in 3-4 weeks. Long-term collaboration possible after launch.

TO APPLY
Please include:
- Your proposed architecture (Vapi setup, UK number, speech-to-text, LLM, text-to-speech, chat, n8n automations, WooCommerce API connection, shared knowledge base)
- How unanswered questions are logged and turned into new answers by the client’s team
- A relevant support system you built (link, demo or case study)
- Rough timeline, budget range and availability

I already have an ORCID ID, but the record is only half-done. I want every section to look complete, polished, and fully aligned with my publication history so anyone—recruiters, grant reviewers, or collaborators—can immediately see an accurate picture of my work.

What I need you to do
• Audit the existing profile and flag any missing or inconsistent data.
• Update personal details, biography, and keywords so they read professionally and use the exact wording I provide.
• Enter or correct employment, education, funding, and organisational affiliations, matching dates and grant numbers to what appears on my CV.
• Import all publications from Crossref, PubMed, Scopus, and any other reliable source, then tidy the record so each work sits under a single DOI without duplicates.
• Link the ORCID to my other researcher IDs and databases (ResearcherID, Scopus Author ID, Google Scholar, etc.) so everything syncs automatically.

Please do the edits directly in ORCID using its bulk-import tools or the API where it speeds things up, and document each step in a brief handover note so I can maintain the profile later. My measure of success is simple: when I refresh the public view, every publication and achievement is there, correctly formatted, and no warning icons appear.

Everything about it.

Skills: Data Entry, Research, Excel, Web Search, Content Writing, Academic Writing, Database Management, API Integration, Data Management, User Experience Research

Outlook-Kategorien für gemeinsames IMAP-Postfach nachbauen

Wir suchen einen erfahrenen Entwickler / Freelancer, der für uns eine Lösung entwickelt, mit der wir in Outlook bei einem gemeinsamen IMAP-Postfach wieder mit farbigen Kategorien arbeiten können.

### Ausgangssituation

Wir haben unser E-Mail-System von Microsoft / Exchange auf IMAP umgestellt.

Früher konnten wir in Outlook E-Mails mit unterschiedlichen farbigen Kategorien markieren, zum Beispiel:

- Michelle
- Benjamin
- Steven
- Tine
- Bestellen
- DHL anfragen
- Retoure angemeldet
- Erledigt
- Angebot
- weitere individuelle Kategorien

Die Kategorien wurden direkt in Outlook angezeigt und konnten über den Button „Kategorisieren“ ausgewählt werden.

Seit der Umstellung auf IMAP unterstützt Outlook diese Kategorien jedoch nicht mehr wie zuvor.

### Ziel

Wir möchten diese Funktion möglichst ähnlich wie früher nachbauen.

Wichtig ist insbesondere:

**Alle Mitarbeiter, die dasselbe IMAP-Postfach in Outlook eingebunden haben, müssen dieselbe Kategorie sehen.**

Beispiel:

Mitarbeiter A markiert eine E-Mail mit:

**Michelle – Türkis**

Dann soll Mitarbeiter B auf seinem eigenen PC bei derselben E-Mail ebenfalls sehen:

**Michelle – Türkis**

Ändert Mitarbeiter B die Kategorie auf:

**Erledigt – Grün**

muss diese Änderung wiederum bei allen anderen Mitarbeitern sichtbar sein.

Die Lösung darf daher nicht nur lokal im jeweiligen Outlook gespeichert werden.

---

## Gewünschte Funktionen

### 1. Zentrale Synchronisation

Die Kategorien / Zuweisungen müssen zentral gespeichert werden.

Zum Beispiel über:

- zentrale Datenbank
- API
- Webservice
- oder eine vergleichbare zuverlässige Lösung

Die Zuordnung sollte idealerweise anhand einer eindeutigen E-Mail-ID / Message-ID erfolgen.

### 2. Outlook-Integration

Die Bedienung soll möglichst direkt aus Outlook heraus erfolgen.

Optimal wäre eine Lösung ähnlich der bisherigen Outlook-Kategorien:

- E-Mail auswählen
- Kategorie auswählen
- Kategorie wird farbig angezeigt

Eine eigene Schaltfläche / Ribbon-Menü / Dropdown wäre ebenfalls möglich.

### 3. Kategorien verwalten

Wir möchten Kategorien selbst anlegen, bearbeiten und löschen können.

Jede Kategorie sollte mindestens enthalten:

- Name
- Farbe

Beispiele:

- Michelle – Türkis
- Benjamin – Blau
- Steven – Pink
- Tine – Orange
- Erledigt – Grün
- Bestellen – Grau
- DHL anfragen – Gelb
- Retoure angemeldet – Orange

### 4. Mehrere Kategorien

Wenn technisch sinnvoll, sollte eine E-Mail auch mehrere Kategorien erhalten können.

Beispiel:

**Michelle + Retoure angemeldet**

oder:

**Benjamin + Bestellen**

### 5. Synchronisation zwischen mehreren PCs

Das ist für uns eine zwingende Voraussetzung.

Wenn mehrere Mitarbeiter dasselbe IMAP-Postfach verwenden, müssen alle dieselben Zuordnungen sehen.

### 6. Persistenz

Die Kategorien müssen erhalten bleiben bei:

- Outlook-Neustart
- PC-Neustart
- Synchronisation des IMAP-Kontos
- Zugriff von mehreren Arbeitsplätzen

### 7. Bestehendes IMAP-Postfach

Das bestehende IMAP-Postfach soll weiter genutzt werden.

Die Lösung soll möglichst keine Änderung am eigentlichen Mailserver oder an den E-Mails selbst verursachen.

Insbesondere soll nicht einfach der Betreff der E-Mail verändert werden.

---

## Technische Offenheit

Wir sind offen für die technische Umsetzung.

Denkbar wären zum Beispiel:

- Outlook Add-in
- Office Add-in
- VSTO / .NET
- Web Add-in
- zentrale SQL-Datenbank
- API / Webservice

Wir möchten ausdrücklich **keine rein lokale VBA-Lösung**, wenn dadurch die Kategorien nicht zwischen allen Mitarbeitern synchronisiert werden.

Der Freelancer darf gern eine bessere Architektur vorschlagen.

---

## Wichtig für das Angebot

Bitte im Angebot kurz beschreiben:

1. Wie Sie die zentrale Synchronisation technisch lösen würden.
2. Welche Outlook-Versionen unterstützt werden.
3. Ob die Lösung im klassischen Outlook und/oder im neuen Outlook funktioniert.
4. Wo die zentrale Datenbank bzw. die Zuordnungen gespeichert werden.
5. Wie die E-Mail eindeutig identifiziert wird.
6. Ob mehrere Mitarbeiter gleichzeitig mit dem Postfach arbeiten können.
7. Ob wir Kategorien später selbst verwalten können.
8. Wie Installation und Updates auf mehreren PCs erfolgen.
9. Welche laufenden Kosten entstehen.
10. Ob der Quellcode vollständig an uns übergeben wird.

---

## Sehr wichtig

Die Lösung soll sich für die Mitarbeiter möglichst ähnlich anfühlen wie die bisherigen Outlook-Kategorien.

Im Idealfall möchten wir wieder eine einfache Bedienung:

**E-Mail anklicken → Kategorie auswählen → Farbe sichtbar → bei allen Mitarbeitern synchron**

Ein Screenshot unserer bisherigen Kategorien kann zur Orientierung bereitgestellt werden.
