Summary
👤
Senior🎓
Top SchoolEd Casillas is a senior software engineer and veteran game developer with over 27 years of experience and a track record of shipping 70+ titles across mobile, web, and desktop. He founded and led ExaGames, managing distributed teams across Europe and Latin America while hands-on architecting and coding games, tools, and marketing assets. His industry experience spans indie studios to tech leaders like Meta—where he worked on Horizon Worlds creation tools—and now Zynga, improving efficiency and stability on Zynga Poker. Comfortable in Unity and C#, he pairs deep gameplay and systems expertise (AI, multiplayer, vehicle systems) with enterprise software and architectural experience from earlier banking and corporate roles. A former university instructor in game development and agile methodologies, he’s as comfortable mentoring teams as he is iterating on gameplay mechanics. Notably, he began making games at 12 and continues to participate in game jams and hackathons, blending lifelong passion with production-grade engineering.
