We are a technical engineering team behind Strix Corporation, a studio specialized in solving complex challenges in Unity and real-time applications. We operate as a team of two senior developers with complementary expertise, allowing us to adapt to a wide range of technical needs and scale depending on project scope. We work with game studios and tech teams as a technical partner, focusing on production-critical topics such as performance, tools, and debugging. Our expertise includes: • Tools & Editor Development (Unity UI Toolkit, custom workflows, internal tools) • Gameplay Systems & Architecture (scalable systems, refactoring, code structure) • Performance & Optimization (CPU/GPU profiling, mobile & console optimization) • Graphics Programming & Shaders (URP, Built-in, OpenGL, rendering systems) • SDK Integration (Firebase, Game Services, native SDKs) • Build Debugging & Technical Support (complex bug investigation, runtime analysis) We have strong experience working on real production constraints, including console platforms such as Nintendo Switch. We also develop internal tools to improve development workflows, including a remote debugging solution for Unity builds used to inspect and modify runtime data in real time. We collaborate remotely with teams and integrate easily into existing workflows, whether for short-term problem solving or longer technical partnerships.
