Flutter Developer Who Ships Apps, Not Just Code
I'm Sakib Hossain — a Flutter and Android developer in Natore, Bangladesh. I've designed, built and published 13 apps to Google Play with 120,000+ downloads between them. I bring that same end-to-end experience to client work.

Why hire a developer who publishes their own apps
Most freelancers hand over a build and move on. I've had to live with mine — through Play policy rejections, target-SDK deadlines, one-star reviews and crash reports at 2am. That changes the decisions you make on day one.
I've shipped through the whole pipeline
Play Console setup, the data safety form, closed testing, staged rollouts, policy appeals. I've done all of it 13 times on my own account, so your release isn't my first.
Flutter in production, not in theory
Ten of my published apps are Flutter. The architecture and state-management advice I give you is what I already run in apps with real users behind them.
Real AI features, already live
AI Quiz Generator and Prolap both ship LLM features to production — including the unglamorous parts: cost control, latency, failure handling and keeping keys off the device.
Apps I've built and published
Every app below is live on Google Play, built and maintained by me. This is the portfolio — not mockups.

What I've learned publishing apps to Google Play — written up so you don't have to rediscover it.
How to Find a Free Budget App That Doesn't Need a Subscription or Your Bank Login
Most people replace their budgeting app because it started charging monthly, or because it wanted their bank credentials, or because it does not support their country at all. Here is what actually matters when you pick the next one.
