About
Mizanur Rahman
I'm a full-stack engineer building systems that handle real money, real traffic, and real consequences if they go down. My domain is event-driven architectures, real-time systems, and high-performance backends.
Most of my career has been in environments where correctness and latency genuinely matter — a trading platform where a slow order execution costs real money, a news portal where 1M+ monthly readers can spike traffic instantly, a microfinance ERP where double-entry accounting must be airtight. I've shipped production systems in all of these.
I work across the full stack: Laravel and NestJS on the backend, React and Vue.js on the frontend, and whatever combination of Redis, RabbitMQ, and WebSockets the architecture demands. I write typed, tested, reviewed code and care deeply about handovers — the next engineer should be able to understand the system without asking me.
I'm currently looking for remote freelance and contract work with AU, US, and UK clients. I work comfortably across time zones and communicate clearly in English.
