Hi, I'm Md Kamrul
Hasan.
Software engineer building scalable Flutter apps and tooling at the edge of the machine. Currently shipping for 50K+ users at BDStall — and quietly mapping the corridor between mobile UI and AI agents.
From logic gates to live apps —
a corridor of small, deliberate steps.
A neon road of milestones. Each marker is a real decision, project, or team I joined.
The stack I build with —
opinionated, but never precious.
A working set, not a wish list. Used in production · refactored quarterly · documented in commits.
Flutter & Dart
Production Android apps with REST integration, MVVM and Clean Architecture. 50K+ daily users on the current stack.
Firebase Suite
Auth, Firestore, Cloud Messaging, Crashlytics. Wired for stability and on-call signal.
GetX · Riverpod
Pragmatic state, picked per project — not per Twitter trend.
Go & REST
Designing JSON APIs, RBAC, and service layers. Optimised the admin response time from days to under one hour.
AI Tooling & Python
Exploring on-device ML, LLM tooling, and useful agents that ship inside Flutter apps — not on a slide deck.
Tools & Workflow
Git, Postman, Android Studio, VS Code. Agile, small PRs, honest reviews.
Selected work,
shipped and supported.
Apps users actually keep on their home screen — measured in retention, not screenshots.
A short, honest timeline.
Internships, junior work, and the years that taught me what to keep — and what to throw out.
