Full-time C# production engineering on a multiplayer, physics-driven Unity 6 title with a 20-30 person multidisciplinary team. Work was organized around milestone delivery, feature ownership, pull requests, QA verification, TeamCity builds and production stabilization.

• Owned implementation of production C# features from ambiguous requirements through architecture, implementation, self-testing, PR review, QA validation, TeamCity build checks and production merge.
• Designed modular runtime systems and internal packages using assemblies, reusable components, interfaces, abstract classes, ScriptableObject-driven configuration and isolated feature test scenes.
• Built designer/audio/QA-facing tools and workflows, including NDA-safe categories such as level-authoring utilities, timer/action scheduling, validation scenes, runtime debug support and level-scoped audio loading.
• Worked with proprietary multiplayer and physics-driven constraints, diagnosing host/client divergence, nondeterministic physics-query ordering, object-interaction edge cases and runtime state problems.
• Improved runtime behaviour using Unity Profiler, Memory Profiler, ProfilerMarkers, allocation reduction, inner-loop investigation, task scheduling and frame-distributed workloads when appropriate.
• Fixed 100+ bugs across milestones, including gameplay defects, multiplayer issues, crash/freeze investigations, FPS/memory regressions and QA-reported production blockers.
• Collaborated through Git pull requests, weekly code reviews, Jira, TeamCity builds, QA test passes and technical discussions with programming, design, audio and production teams.
