Open to exciting opportunities
Hello, I'mKAMRUZZAMAN
Crafting scalable, high-performance systems as a Full Stack Engineer.
About Me
The mindset, the experience, and the curiosity behind the software I build.
Craft
I turn tangled problems into simple, maintainable software that a team can keep building on years later.
Scale
Multi-vendor marketplace code that has to hold for thousands of stores at once, where a slow query is an outage.
Now
Exploring AI-assisted engineering and agent tooling, and what they change about how software actually gets written.
End to end
5+ years taking features from schema to deploy: APIs, queues, Docker images, and the AWS wiring behind them.
I build and maintain multi-vendor marketplace software: payment gateways, ERP integrations, and the WordPress plugins that hold them together. Most of my time goes to Dokan, where a change has to work for thousands of stores at once.
The work I enjoy most sits where system design meets performance: finding the query that got slow as the data grew, drawing a boundary that makes a feature testable, and leaving code the next person can read.

One movie, 190 countries, zero buffering: how Netflix answers the interview

10 min readOne movie, 190 countries, zero buffering: how Netflix answers the interview
A system-design case study of the classic Netflix question — 120 million simultaneous streams, 4–15 Mbps each, no buffering. We do the napkin math, show why a data centre cannot serve it, and walk through Open Connect, adaptive bitrate and the control-plane / data-plane split that actually make it work.
