🎮 Senior Game Developer | Unity & Unreal Engine | Mobile & PC Games I help indie developers and game studios build, improve, and ship high-quality games using both Unity and Unreal Engine. With over 10 years of professional experience, I've worked on gameplay systems, rapid prototyping, performance optimization, bug fixing, and release preparation across a variety of genres and platforms. Whether you need to build a feature from scratch, rescue an existing project, or polish a game before launch, I can help deliver a stable, scalable, and enjoyable player experience. My expertise includes: • Unity (2D & 3D) • Unreal Engine • C# and C++ • Gameplay programming • Gameplay mechanics and game systems • Mobile game development (Android & iOS) • PC game development • Performance optimization (CPU, GPU, memory, FPS) • AI, physics, and animation systems • Bug fixing and debugging • UI implementation and game polish • Code refactoring and project maintenance I enjoy solving complex technical challenges while keeping projects clean, scalable, and maintainable. Whether working in Unity or Unreal Engine, I focus on writing reliable code that is easy to extend and supports long-term development. Before freelancing, I worked as a Software Engineer at the IT Support Center of the Hellenic Army, where I developed software with a strong emphasis on reliability, structure, and long-term maintainability. What you can expect when working with me: • Clear and consistent communication • Reliable delivery and realistic estimates • Clean, maintainable, and well-structured code • A proactive approach to identifying and solving technical challenges • Commitment to delivering polished, production-ready results If you're looking for an experienced game developer who can contribute throughout the entire development cycle—from prototype to release—in either Unity or Unreal Engine, I'd be happy to discuss your project.

I am a game developer with over 7 years of professional experience working with Unity, mainly developing mobile games. My main expertise includes gameplay programming, bug fixing, performance optimization, and implementing game systems using C#. I have worked on multiple mobile game projects where I focused on building stable, optimized, and scalable gameplay systems. I can help with: • Unity bug fixing and debugging • Gameplay systems implementation • Mobile game optimization (FPS, memory, performance) • Android builds • Web tools and backend support for games In addition to Unity development, I also have experience working with Unreal Engine 5 while developing my own PC game project. This gives me additional knowledge about modern game development pipelines, lighting systems, and performance considerations across different engines. I also have a background in full-stack web development, which allows me to build APIs, game tools, dashboards, and supporting web systems for games. I focus on clear communication, fast problem solving, and delivering reliable solutions for game projects.

I build complete, polished games fast — using an AI-native pipeline that ships in 2-4 weeks what normally takes a small team months. 12+ years in game development across mobile, AAA, and indie. If you have an idea, a prototype, or a game that needs finishing, I can take it end-to-end. What I do: - Full game builds — Unity (C#), Roblox (Luau), HTML5/web, and mobile (Android/iOS) - Rapid prototypes & MVPs — turn your concept into a playable build quickly - AI-powered production — every asset (art, audio, animation, code) generated and human-curated for speed without sacrificing quality - Game systems & mechanics — combat, progression, economy, multiplayer, monetization - Live-ops & growth — A/B testing, retention tuning, funnel optimization My AI build stack: Claude Code (engineering & game logic) · Nano Banana 2 (art & assets) · Suno (music & SFX) · Veo3 (animation & trailers) · ElevenLabs (voice). This is what lets me move at a speed most studios can't match — the human craft stays in design, architecture, and curation; the AI handles the heavy lifting. Recent work (last 3 months alone): - 3 Roblox games built and shipped, with full UA, retention, and monetization tuning - An HTML5 game live on CrazyGames - Dragon Era Online — reviving my mobile MMORPG (1M+ downloads on Google Play) for a Steam PC release, including its real-time multiplayer netcode Background: - Solo-built and published a mobile MMORPG that reached 1M+ downloads on Google Play - Founded and ran a game studio for 5 years — scaled to a 20-person team, shipped live titles, 7-figure revenue - Worked on AAA mobile slot games at Murka (15M+ downloads across the portfolio) - Strong across Unity, Godot, Roblox, real-time multiplayer (Mirror, Photon), and full-stack game development Whether you need a game built from scratch, a prototype validated, an existing project finished, or someone who can simply move faster than the usual dev cycle — let's talk. I respond quickly and I ship.

I build Unity games and features across mobile, PC, WebGL, and consoles. I've completed 40+ projects and spent time leading development at an indie studio, so I know what it takes to turn a concept into a shipped game without last-minute chaos. Most of my work falls into three buckets: Development - Whether it's a new system, a gameplay mechanic, or a half-built project that needs finishing, I write clean, well-documented C# following SOLID principles, so whoever touches the code after me (including future you) isn't stuck guessing. Integration - Firebase, in-app purchases, ad networks, analytics, cloud saves, push notifications. I handle the backend that keeps a live game running, and I also handle porting and deployment to iOS, Android, PC, WebGL, and consoles. Performance & Polish - Slow loads, frame drops, bloated builds, choppy UI. I fix these with Addressables, object pooling, profiling, Cinemachine camera work, FMOD audio, and VFX that don't tank your frame rate, so the game runs well and feels like a real product. Send me what you've got, whether it's a concept, a half-finished project, or a live game with problems, and I'll tell you straight what's realistic and what it'll take. Ivaylo
