I build AI-powered web and mobile products end to end — from OpenAI integration and database design through to production deployment. Most freelance work sits behind an NDA, so here is one you can inspect yourself. Cited Extract is an open-source tool of mine, live and running: you define the fields you want, paste in a contract, and get typed JSON back where every value cites the exact sentence it came from. Fields the document doesn't contain come back null instead of a confident guess — a value is discarded unless its quote is found verbatim in the source. Live demo and full source are in my portfolio below. Recent client work: ● My PD Buddy — AI product-development platform for cosmetics. Built the whole product end to end, AI included: three GPT-4 agents. Compliance Buddy checks ingredients against FDA and EU regulations and generates compliance reports; Formulation Buddy writes and analyses formulas; Innovation Buddy generates new product ideas and renders a brand's logo onto blank packaging. Next.js + OpenAI. ● Chatalyst — AI candidate-screening platform. Built the frontend that presents GPT-4 screening results — ranked shortlists and applicant summaries — for recruiters to review. ● Oteogo — AR learning platform for kids (Next.js, Node.js, MongoDB, AWS). Full-stack developer since 2024. Built email verification, parent progress reports, per-child game access, leaderboards and admin tools. Moved the web app to TypeScript and the backend to ES modules and Mongoose 8. Built isolated dev and staging environments on AWS beside live production, with least-privilege IAM and MFA. Fixed access-control, entitlement, stats and Stripe billing bugs. Added automatic 3D model framing in Three.js, and coordinated a verified production release. Client review: "Reliable, transparent, technically thorough, and easy to work with." ● JustConnect — Danish marketplace connecting homeowners with contractors. Task posting, tailored offers, bid comparison, contractor profiles. Next.js + Supabase. ● Four apps live on the App Store, built in React Native, Swift and Unity — including watchOS widgets with real-time health data. What I work with: Front-end — TypeScript, JavaScript, React, Next.js, React Native, Redux Toolkit / RTK Query, Tailwind CSS, Material UI, Bootstrap Back-end — Node.js (Express.js), Laravel, Supabase, Prisma, Mongoose, REST & GraphQL API design AI — OpenAI GPT-4, structured outputs, document analysis, automated workflows, retrieval and compliance pipelines, conversational assistants Mobile — React Native, Swift, SwiftUI, Objective-C, iOS, watchOS, WidgetKit, SwiftData Databases — PostgreSQL, MySQL, MongoDB, Firebase Infrastructure — AWS (Elastic Beanstalk, S3, IAM, ALB, ACM), MongoDB Atlas, Nginx, Docker, Git (GitHub/GitLab), CI/CD pipelines, staging & production environments Integrations — Stripe, Plaid, RevenueCat, OAuth (Google, Facebook, Twitter), Twilio, Sendbird, Metamask, Telegram & Slack bots How I work: you get a staging link early and updates you can check yourself, rather than silence for two weeks and a surprise at the end. I scope clearly up front and flag problems when I find them, not after they cost you money. Available 30+ hrs/week, based in Pakistan (UTC+5) with strong overlap for EU clients and morning overlap for US East Coast. Tell me what you're building and I'll give you an honest read on whether I'm the right fit and what it will realistically take.
