On Building Systems That Run When You Sleep
By Tafsir Chowdhury — Dhaka, Bangladesh
Backend-first by philosophy, full-stack by necessity. I have spent the last three years writing the code that most users never see — the worker queues, the retry logic, the LLM orchestration layers — the infrastructure that makes products feel effortless.
At Standard Insights, I architect multi-phase AI pipelines using durable Inngest functions, own distributed worker microservices across multiple queue types, and build REST APIs that handle real production load. Before that, at HJ Animation Shop, I built Aximus — an autonomous AI customer support platform powered by RAG and tool-calling agents.
I hold a Bachelor of Science in Computer Science from the University of the People (CGPA 3.67), and carry software engineering certifications from IBM, Meta, and AWS.
