Hey, I'm Mizanur
backend systems, clean APIs, and the trade-offs behind them.
I'm a software engineer with 3.5 years building backend systems, currently the technical lead on RenoSafe at WebAlive - a multi-tenant construction-finance platform where I own the Stripe payment and escrow rails and the Postgres row-level security that keeps tenants isolated.
Before that, at Bit Mascot, I authored the public REST API (v4) for Exsited/AutoBill - roughly 370 endpoints across 116 entities - along with the filtering, permission, and OData layers other teams built on.
I like the hard, unglamorous parts of backend work: correctness under concurrency, data integrity, and APIs that stay stable as the system underneath changes. On the side I build things to learn how systems really work (Bildora, Flyvisto, PFM), and lately I'm going deep on AWS and Kubernetes.
