I'm Chase, a Senior Software Engineer with 10+ years of experience owning full-stack systems across multiplayer games, cloud backend infrastructure, and developer tooling. At my most recent role, I was the sole engineer accountable for an entire live multiplayer game's technical stack - client systems, dedicated server infrastructure, backend APIs, database architecture, CI/CD pipelines, and live operations - effectively filling six specialized engineering roles simultaneously. I don't just contribute to systems. I own them end-to-end, from initial architecture through production stability and live deployment. My background spans Unity/C#, Azure/AWS, MongoDB/Redis, multiplayer networking, platform integrations (PlayFab, Epic Online Services, Steamworks, Easy Anti-Cheat), and backend API design. I've shipped production systems at Blizzard Entertainment on StarCraft II and led all engineering on a live multiplayer title at tinyBuild.
