01About

I'm Rakhul, a CS engineer who likes building things that people actually use.

My focus is mobile development with Flutter, from architecture and performance to edge cases and deployment. I've worked on startup products, open-source projects, and real client apps, where reliability matters more than demos.

I'm at my best when I can take ownership, learn fast, and turn messy problems into solid, shippable software.
