Senior Full-Stack + AI Engineer based in Karachi. 5+ years shipping production systems across fintech, e-commerce, and enterprise SaaS.

Currently at Afiniti, leading a 3-engineer team building AI middleware on AWS Bedrock + Model Context Protocol for the US Social Security Administration (100,000+ agents). I also own Keycloak SSO across our multi-tenant infra. Took it from v15 to v25 and cut token issuance P95 by ~35%.

ShiftSync. Solo build. A multi-location staff scheduling SaaS with a LangGraph.js AI copilot. The copilot has 7 tools, every write call hits a human-in-the-loop checkpoint via interrupt(), conversation state is Postgres-checkpointed, and audit logs are agent-namespaced so manager actions stay distinguishable from AI actions.
