Software Engineer
I'm a software engineer from Dhaka with 2 years of experience, mostly on the backend. In my previous role I worked on a Node.js ad-serving engine handling millions of requests a day, built an AI-powered ad creative tool, and ran SMS delivery services with Bangladesh's major telecom operators.
What sets me apart is how I approach problems: I like to design first, weigh trade-offs, and treat security as part of the architecture rather than an afterthought. In my Secure RAG Q&A system, I raised retrieval accuracy from 61% to 91% and cut prompt-injection success from 47.5% to 0%, measuring every change against an eval set. In MediQueue, a multi-tenant SaaS, I used PostgreSQL row locking and RLS so 50 simultaneous requests produced zero duplicate tokens and tenant data stayed isolated.
I'm looking for a backend or full-stack role (Node.js, TypeScript, Python, PostgreSQL) on a team that values careful engineering, system design and building for scale. I'm open to on-site work in Dhaka or remote roles.
