Bibek Timsina
AI Full-Stack Engineer
I build products end-to-end with TypeScript, Cloudflare, PostgreSQL, and LLMs for remote teams. Currently leading engineering for Proma.aiat Growthzilla.
Featured Projects
A few projects that show how I think about product engineering, developer tooling, AI systems, and scale.
Proma.ai Engineering
Lead engineering and product direction for Proma's AI assistant: a front-office worker that answers a business's customers, works for the owner, and builds the systems the business runs on.
Doodleblaze
Multiplayer drawing race judged by AI. Everyone draws the same word at once, and the first doodle Cloudflare's Clef model recognizes past 75% wins the round. Built on Workers, Durable Objects and Workers AI.
Flaremender
Open-source agent that explores your app in a real browser, writes and repairs Playwright tests, and runs them on a schedule. Self-hosted on your own Cloudflare account with a one-click deploy.
Callbreak Multiplayer
Real-time multiplayer card game built from zero to 1,000,000+ Google Play downloads, with Firebase-backed matchmaking and rejoin flows.
