I build full-stack web apps and AI automation that go to production: React.js, Next.js, TypeScript and Node.js for the product, with Python (FastAPI), OpenAI, LangChain and RAG for the AI layer. Selected work (details in my portfolio): - Mortgage lending (fintech): RAG assistant for mortgage guidelines that answers from source documents, with citations. - Healthcare: assistant over patient-record (FHIR) data, with multi-agent validation. - Business services (UAE): multi-tenant AI receptionist for small businesses that answers calls, WhatsApp and email, books meetings into the owner's calendar, and replies only from each company's own knowledge base. - Skilled trades: full-stack social platform for tradespeople, with AI-generated post descriptions. I take on SaaS products and dashboards, AI agents and chatbots, AI workflow automation and AI integration into existing systems, RAG over your documents, n8n and API automations, Stripe billing, and deployment on AWS or GCP with PostgreSQL or MongoDB.
