Sobre mim
I'm Umair, a full-stack and AI engineer with 5+ years shipping production software, not prototypes.
What I do:
1. AI products: RAG systems, AI agents, document processing, and chatbots grounded in your data so they don't invent answers.
2. Full-stack builds: SaaS platforms, dashboards, CRM/ERP, eCommerce, and the APIs behind them.
Recent: a multi-tenant SOC 2 compliance platform with RAG search, an AI property-report engine on live UK government data, and a store running 6 payment gateways.
Stack: Next.js, React, Node, TypeScript, MongoDB, OpenAI, Gemini, AWS.
