🎮 Unity & Unreal Game Developer | Mobile & PC Games I help indie developers and small studios turn game ideas into polished, high-performance products — from early prototypes to release-ready builds. With 10+ years of experience, I specialize in: • Unity game development (2D & 3D) • Mobile games (Android & iOS) • Gameplay systems & mechanics • Performance optimization (FPS, memory, build size) • Bug fixing and project polishing 💡 I’m especially useful if you: • Have a prototype that needs finishing • Need to improve performance or fix issues • Want a clean, scalable codebase for your game Previously, I worked as a Software Engineer at the IT Support Center of the Hellenic Army, where I developed strong attention to reliability, structure, and problem-solving. ✅ Clean, maintainable code ✅ Clear and consistent communication ✅ Reliable delivery — no missed deadlines If you need a developer who can take your game from “almost there” to “ready to launch,” feel free to reach out.

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 and stabilize Python/FastAPI backends that scale - clean APIs, reliable deployments, and automation that removes operational pain. If your product is slowing down because of bugs, bottlenecks, or messy integrations, I turn it into a maintainable system your team can ship with confidence. 🎯 Typical outcomes ✔️ Production-ready APIs – REST / GraphQL with FastAPI, clear contracts & tests ✔️ Microservices & integrations – auth, messaging, caching, service-to-service ✔️ High-performance data layers – PostgreSQL, MongoDB, Redis ✔️ Reliable environments – Docker, Docker Compose, CI/CD ✔️ Automation that saves time – scripts for reports, syncs, migrations 🧠 How I work 1️⃣ Clarify requirements & success criteria 2️⃣ Propose a short, concrete technical plan (milestones, risks, estimates) 3️⃣ Implement with clean commits, documentation, and proper handover 📩 Share your repo or tech stack + the main pain point, and I’ll reply with a concrete plan and the fastest path to production.

I build, optimize, and ship Unity games across mobile, PC, WebGL, and consoles. With 40+ completed projects and experience leading development at an indie studio, I focus on clean architecture, smooth performance, and getting your game to launch without surprises. Most of my work falls into three areas: Performance & Optimization Slow load times, frame drops, bloated builds — I solve these with Addressables, object pooling, profiling, and UI optimization so your game runs well on the devices your players actually use. Integration & Deployment Firebase, in-app purchases, ad networks, analytics, cloud saves, push notifications — I handle the backend wiring that keeps a live game running. I also port and deploy across iOS, Android, PC, WebGL, and consoles. Polished Player Experience From responsive UI and smooth animations (2D, bone, Spine) to dynamic camera systems (Cinemachine2D), FMOD audio, and optimized VFX — I build the layer that makes a game feel professional, not just functional. I write well-documented C# following SOLID principles and established design patterns, so the next developer (or future you) can pick up where I left off. I've worked as a Senior Developer coordinating full development cycles from prototype to release. If you have a game concept, a half-built project, or a live title that needs fixing — send me the details and I'll tell you exactly what's possible. -Ivaylo
