Three of my apps have 10K+ downloads each on the App Store and Google Play, and a logistics platform I built reconciled 48,427 tonnes in a single shipment. I take AI features, MVPs and half-finished apps from "works in the demo" to production: web, mobile and the backend behind them. WHAT CLIENTS HIRE ME FOR • AI integration for existing apps: add AI features (chat, smart search, recommendations, image analysis) to your current iOS, Android or web app without rebuilding it. • Prototype to production: your AI MVP built with Cursor, Lovable or ChatGPT works as a demo. I make it reliable, secure and ready for real users. • Custom AI chatbots & RAG: assistants that answer from your own documents and data, show the source, and say "I don't know" instead of inventing an answer. • AI agents that take real actions: agents that search, book, update records and call your APIs, with permissions, limits and human approval where it matters. I also build MCP servers so assistants like Claude and ChatGPT can use your product. • AI-powered mobile apps from scratch: full iOS & Android app, backend and store release, with AI built in from day one. PROOF: AI RUNNING IN LIVE APPS Mechanic Connect (Jamaica): customers photograph a car problem, a vision AI model analyses the photo, suggests the likely issue and routes the request to the right garage. 3 Flutter apps + ASP.NET Core API, live on both stores. ATAYA (Senegal): booking marketplace with 10K+ downloads. I built a key-gated Partner API that lets an external AI assistant search, quote and book real activities, with hashed API keys, rate limits and signed webhooks. Payments through Wave, Orange Money and PayTech. Maman Tontine: fintech group-savings app with 10K+ downloads and payouts through the Wave and Orange Money APIs. CargoControl: Flutter + Next.js + .NET logistics platform. 48,427 tonnes reconciled in a single shipment. HOW I KEEP AI RELIABLE • Answers grounded in your data, with sources shown to the user • Structured outputs and validation, so a bad model response can't break your app or overwrite data • Guardrails, fallbacks and handover to a human when the AI isn't sure • Logging, usage limits and cost control from day one • The right model for each task: OpenAI, Claude or Gemini WORKING WITH ME • I personally write the code. No hand-offs. • You own everything: repository, cloud accounts and API keys stay under your logins. • Clear documentation and a proper handover, so your team can run it without me. • Milestones with working builds you can test on your phone or in the browser. STACK AI: OpenAI API, Claude API, Gemini API, RAG, vector search, AI agents, tool calling, MCP, vision AI Apps: Flutter (iOS, Android, Web), Next.js Backend: ASP.NET Core / .NET, Firebase, PostgreSQL, REST APIs, payment and third-party API integrations HOW TO START Already have an app or prototype? Send me a short description or the repo, and tell me what the AI should do (or what it's doing wrong). I'll reply with an honest assessment: what to build, the right AI approach, and a realistic timeline. Only have an idea? Send the idea. I'll tell you what's worth building first.
