Need highly optimized Unity or Godot gameplay systems, or a scalable Python FastAPI backend? I am a Game & Systems Engineer specializing in decoupled architecture, multiplayer state synchronization, and robust server-side infrastructure. Whether engineering authoritative multiplayer logic, building cross-engine gameplay systems, or building asynchronous production-ready APIs, I deliver fail-safe, documented systems. 1. GAME ENGINE ENGINEERING (Unity & Godot) I build scalable 2D and 3D game systems across Unity and Godot 4.x, focusing on modular framework design rather than brittle movement scripts. • Cross-Engine Game Development: Designed and built 15 Unity titles spanning 2D pixel-art platforming, 3D action-combat, sports simulation with adaptive AI opponents, and mobile puzzle/arcade genres, several of them published and live on Google Play. • Complex Systems Engineering (Godot): Built complete multiplayer tournament logic, handling multi-controller input, physics layers, and real-time state sync for a physics-driven competitive game. • Engine & Physics Optimization: Profiling and resolving frame-rate bottlenecks, refining physics/collision layers, and ensuring rock-solid performance across PC, Android, and mid-tier hardware. • UI & Modular Tooling: Designing dynamic HUDs, responsive tournament brackets, case/investigation-style UI systems, and custom in-engine editor tools (Godot Control nodes; Unity UGUI). 2. PYTHON & BACKEND ENGINEERING (FastAPI & Infrastructure) I build production-ready backend services, automation pipelines, and API integrations that power software ecosystems and high-throughput applications. • FastAPI & Microservices: Architecting high-performance, asynchronous REST APIs for data processing, user state management, and external system integrations. • Automation & Tooling: Engineering custom CLI utilities, automated build pipelines, and zero-touch asset workflows to eliminate operational overhead. • Systems Optimization: Refactoring legacy Python scripts to fix memory leaks, optimize execution time, and ensure thread-safe concurrency. WHY WORK WITH ME? Whether you need an engine specialist to untangle complex gameplay mechanics across Unity or Godot, or a backend developer to architect a secure, high-concurrency FastAPI service, I bring rigorous systems-level engineering to every project. No spaghetti code, just documented, scalable, and fail-safe architecture. Let's build your system right the first time.
