Md Tanvir Alam

Senior Software Engineer · Senior Backend Java · Agentic AI

I am CTO and a hands-on senior engineer with 5+ years on high-concurrency banking backends and production Agentic AI. I design Java/Spring microservices, Kafka pipelines, and MCP/RAG services that hold up in regulated environments. This year I got patches merged into Google Gson, Facebook Infer, Apache Maven, Apache Commons IO, and Netflix DGS.
