RK Rashel Khan

Android Developer · Bangladesh

I build Android apps
and chase good roads.

Hi, I’m Rashel Khan. I design and develop mobile apps that solve small, real problems — clean interfaces, fast performance, and no unnecessary data collection. When I’m not shipping an update, I’m usually somewhere on a bus with a window seat.

About me

Developer by trade,
traveler by habit.

I have been writing software for years, mostly for Android. I enjoy the part of the job where a messy, real-world problem turns into a screen that anybody can use without instructions.

I care a lot about privacy. My apps ask for the fewest permissions possible, keep data on the device whenever it can, and never sell anything to anyone. You can read exactly how that works in my privacy policy.

Outside of work you will find me planning the next trip — hills, rivers, or just a town I have never seen before.
