I build AI-powered full stack products and ship them end to end, from RAG and semantic search down to the interface on top. I am not a code-to-spec contractor. I build and run my own SaaS, so you get an engineer who thinks like a product owner and can take a rough vision and turn it into something live. Top Rated Plus with a 100% Job Success Score, 6+ years across fintech, e-commerce, and Web3, and most of my work now sits where AI meets full stack product engineering. What I build: - AI products and integration. RAG and knowledge-base pipelines, semantic and hybrid search (BM25 + kNN), embeddings, LLM-driven workflows, and voice agents with speech recognition. I have shipped this in my own products and for clients, not just in demos. - Full stack SaaS. Next.js and React on the front, Node, FastAPI, and Supabase on the back. Auth, Postgres, migrations, edge functions, and background jobs, built to scale and to maintain. - Payments and fintech. Paystack, Flutterwave, Stripe, and African gateways, with secure checkout, onboarding, and money-movement flows. - Product design. I am also a UI/UX designer working in Figma design systems, component libraries, and design tokens, so I can take a product from interface design through to shipped code without a handoff gap. Selected work: - Hospitally, my own live hospital-discovery platform for Nigeria: natural-language AI search over deduplicated, structured data, with a location-aware architecture. - Concierge, my own voice-AI platform for African businesses: a multi-agent architecture, RAG knowledge bases, and speech recognition tuned for Nigerian languages. - Entitled AI, a live AI platform for first-time home buyers: conversational guidance, pre-approval estimates, and automated document review with red-flag detection. - Valuna AI, an AI content engine that generates product descriptions, images, and FAQs for e-commerce. - A high-traffic treatment and mental-health directory serving 3M+ users, where I cut page load time by 60% and shipped conversion features that added roughly $500K in annual revenue. - BeautyBoss, my live Shopify app rated 4.6: an automated private-label workflow with an instant label editor and 3D mockup rendering. - Numbrs - Figo Payment, a Lagos fintech where my front-end work processed ₦40M+ in monthly transactions and a redesigned onboarding lifted adoption by 200%. How I work: I ship end to end and own the outcome, not just my slice of it. I am honest about scope: if something needs to be defined before I can quote it properly, I will say so rather than guess. And because I build my own products, I will tell you when a feature is not worth building, not only how to build it. Tech I work with: TypeScript, JavaScript, Python, React, Next.js, Node, Express, FastAPI, Laravel, Supabase, PostgreSQL, GraphQL, Elasticsearch, vector search and embeddings, AWS (Lambda, S3, EC2), Google Cloud, Docker, Tailwind, shadcn/ui, Radix UI. Testing with Vitest, Playwright, and Cypress. If you are a founder or team that needs AI features actually shipped and not just prototyped, send me a message with what you are building and I will tell you honestly how I would approach it.
