Hire the Best C Programmers & Developers
in Ukraine

Senior Unity Engineer (10+ years) shipping games and interactive apps across mobile, PC, and WebGL. I thrive on complex problems and have a keen eye for detail—whether that’s refactoring tangled codebases into clean architectures, removing performance bottlenecks, or integrating production features like MediaPipe and LLM APIs. Recent work: • Mosquito Coast — multi-screen interactive framework (patented; 5-year engagement) • Ablizmo / “OVERLODE” — real-time RTS/deck-building UI overhaul + systems work • Atomic Starman — narrative tooling pipeline (Articy + Dialogue System) • Earlier: WebGL 3D medical visualization, mobile simulation apps, gameplay systems & bug fixing What I do best: 🧩 Gameplay / UI Systems • Modular C# systems, state machines, event-driven architecture • UI architecture (MVC/MVVM), responsive UX, tooltips, menus, data-driven UI 🚀 Performance & Stability • Profiling CPU/GPU, reducing GC/memory spikes, smoothing frame time • Pragmatic refactoring that improves stability without risky rewrites 🛠 Architecture, Refactoring & Tools • Turning large/legacy code into maintainable modules • Editor tools + workflow improvements to speed up teams 🤖 AI / LLM Integrations (when useful) • Integrating APIs (OpenAI/Claude), prompt + data flow design, guardrails • I also use modern coding assistants to speed up delivery while keeping code production-ready How I work: I’m MVP-first: identify the highest-impact tasks, prototype quickly to de-risk, then build scalable solutions. I’m comfortable in distributed teams, communicate directly, and I’m not afraid to dive deep into debugging. What I’m looking for: • Gameplay programming, UI & systems development • Optimization, stabilization, refactoring legacy projects • Mobile & WebGL projects • Internal tools development • AI-assisted features, AR prototypes If you want a senior Unity developer who can ship fast, improve code quality, and make your project stable and scalable — I’d love to help.
