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 12 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 12 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.

Notes from building and shipping
What I've learned publishing apps to Google Play — written up so you don't have to rediscover it.
12 Apps, 120,000 Installs, $252 a Year
My app with 100,000 installs earns almost nothing. My app with 10,000 earns 95% of my revenue. Here are the real numbers from 12 Google Play apps, and what they taught me.
Why the Land You're Buying Measures Smaller Than the Deed Says
The deed says 10 shotok. You measure 8.6. Before assuming anyone is lying, here are the five reasons that gap appears — and how big a gap should actually worry you.
How to Measure Land Without a Surveyor
Four ways to get the area of a plot yourself, what each one is good for, and where each one goes wrong. Use them to screen plots — then pay an amin for the one you buy.
