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.

White-Label Sports Betting Platform

A fully-featured mobile-first sports betting application.

Problem
The client needed a white-label based sports betting frontend that could be skinned for multiple brands while supporting real-time market data over WebSockets.
Solution
Engineered an Angular + Ionic hybrid application with NgRx SignalStore for reactive state management and Web Workers for off-thread WebSocket processing, ensuring smooth UI performance under high-frequency data updates.

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.
