I’m a Senior Gameplay Engineer with 15+ years of experience building mobile games from early prototypes through global launch and live operations.I specialize in turning ideas into playable prototypes quickly, validating them with real player data, and evolving them into scalable, production-ready systems. I’ve worked across the full lifecycle of games, from greenfield concepts to live titles generating millions in revenue.At Glu Mobile, I was the lead client engineer on Diner Dash Adventures, where I helped define the client architecture and built core systems including avatar customization and a Battle Pass feature that drove millions in additional revenue and improved retention.At Electronic Arts, I worked on Covet Fashion, where I led initiatives to reduce technical debt and improve player experience. This resulted in fewer ANRs, a higher app store rating, and ultimately contributed to increased visibility and revenue.I’ve also led and mentored engineering teams, but I remain deeply hands-on. I enjoy solving complex gameplay and systems problems, improving performance, and building features that directly impact player experience and business outcomes. Core areas:- Gameplay engineering (Unity, C#, C++)- Rapid prototyping and iteration- Live ops systems (Battle Pass, progression, monetization)- Performance, stability, and scalability on mobile- Cross-functional collaboration with design, product, and artI’m most interested in teams that value speed, ownership, and building games that actually make it to players.
