About

Crafting apps people
love to use

I'm a Flutter developer based in Nepal who cares deeply about the craft — from pixel-perfect UI to bulletproof architecture. My strength is bridging complex backend systems with intuitive, responsive frontends that feel natural on every screen size.

Currently at Saransa Media Labs, working across two products — Weetok, a short-video platform, and Sajiloplay, a game competition platform. I've built everything from end-to-end encrypted messaging to adaptive ad-delivery algorithms there. Increasingly I work further down the stack too: FastAPI backends, PostgreSQL, and the data modelling that decides whether an app's numbers can actually be trusted.

Portfolio

Featured Projects

KharchaMate

In Development

An Android money app that splits expenses with groups and manages personal finances under one accounting model. Most split apps tell you what you paid; this one tells you what things actually cost you. Money you front for a group isn't counted as spending until the group settles, money set aside for a goal is parked rather than spent, and repayments are never income. A custom settlement algorithm clears multi-member debts in the minimum number of payments, and the app reads and writes offline, syncing when the connection returns.

Uniquely includes a built-in local WebSocket server — any device on the same Wi-Fi can follow the live scores in a browser, no extra app or backend needed.
