Flutter Developer · Kathmandu, Nepal

Building things
people actually
reach for.

I craft mobile experiences with Flutter — clean architecture, real-time features, and the kind of polish that makes users forget they're using an app.

About

I'm a Flutter developer based in Kathmandu, Nepal. I graduated with a BCA from Kantipur City College in 2024 and have been shipping production apps since — from VoIP platforms and CRM systems to social media apps with real-time chat and video calling.

I care about the details that are easy to skip: race conditions in state transitions, platform-specific edge cases, and the micro-interactions that make an app feel right.
