Huddle — Self-Hosted Video Conferencing

A self-hosted, browser-based video conferencing app built on LiveKit.

Problem
Cloud-based video platforms compromise your privacy, lock you into their ecosystem, and charge for features you need. You want real-time collaboration without sacrificing control or paying recurring fees.
Solution
Built a complete self-hosted video conferencing solution using LiveKit for WebRTC media, NestJS for token management and room services, and Next.js for the frontend. Users can host their own meetings with full control over infrastructure and data.

Lynx — Word Guessing Game

A real-time multiplayer word guessing game with voice communication.

Problem
Classic word games lack real-time social interaction, making remote play feel disconnected and less engaging.
Solution
Built a synchronized multiplayer experience using Colyseus for real-time game state and LiveKit for WebRTC voice communication, enabling a fully social gameplay loop.

Triads — Word Puzzle Game

A word puzzle game where players find hidden keywords connecting groups of three cue words.

Problem
Word puzzle games often feel static and visually flat, with no sense of physicality or progression — and most require account creation just to play.
Solution
Built a fully accountless experience with physics-based floating bubbles (Matter.js) and fluid GSAP animations to make the puzzle feel alive. All player identity and statistics are stored locally, removing any friction to start playing. The backend stays stateless per player, focusing purely on serving and validating puzzle content.

open to work

I'm a passionate Full-Stack Developer with 5+ years of professional experience building everything from enterprise web applications to real-time multiplayer games.

My journey started at Addis Ababa Universitywhere I studied Computer Science, and I've been building things for the web ever since. I love working across the full stack — architecting backends with Nest.js, crafting responsive frontends with Angular and React, and wiring them together with clean, maintainable TypeScript.

When I'm not writing code, you'll find me exploring new technologies, contributing to side projects like Lynx, or thinking about the next thing to build.
