Hadi Sajjadi
Senior Game Developer
My 6-year journey in game development has been an absolute passion project. I've spent my career deeply immersed in Unity, crafting a diverse portfolio that includes everything from quick and fun casual games to long-term, player-driven free-to-play live service titles. I've also loved venturing into the world of WebGL, using tools like Cocos Creator, Pixi.js, and Unity to bring games to life directly in the browser.
