Senior🎓
Top SchoolSean Cooper is a senior software engineer with 15 years of experience specializing in game tooling, engine-level fixes, and full-stack developer workflows, currently working on Unreal projects at Halo Studios in Redmond. He led the PC modding initiative and tool releases for Halo: The Master Chief Collection, migrated large UGC systems to PlayFab/XForge, and has deep experience shipping engine and build-pipeline improvements across multiple AAA titles. Sean blends hands-on reverse-engineering and low-level systems work (including PPC assembly and IL2CPP expertise) with community-facing roles—running Halomods.com and collaborating directly with modders and external partners. He maintains active open-source contributions such as enhancements to the Gemini IDE framework and has a track record of refactoring, NuGet/.NET upgrades, and tooling that reduced build sizes and improved asset pipelines. Comfortable in both sustainable live-ops and new-feature prototyping, he pairs pragmatic problem-solving with clear technical communication, having authored technical blog sections and guided partner code reviews. Notably, his background includes military IT and finance roles, giving him disciplined operational and security-minded perspectives uncommon in pure game engineering profiles.
