Hire the Best Xbox Developers

I build responsive, polished gameplay systems in Unity—focused on mechanics, AI, and performance. If your game feels “almost there” but lacks smooth mechanics, smart AI, or optimization—I can help turn it into a complete, playable experience. I’m a mid-level Unity developer with 2+ years of experience, specializing in 2D and 3D gameplay systems using C#. I focus on building mechanics that feel good to play, not just systems that work. 🎮 What I can do for your project: Gameplay mechanics (movement, combat, abilities, physics-based systems) AI systems (state machines, behaviors, enemy logic) Full game systems (core loops, progression, interactions) Optimization (fix FPS drops, improve performance for mobile/PC) UI & animation integration (including Spine) Debugging and fixing broken Unity projects 🚀 Featured Projects 🕸️ Swingfall (Rogue-like 2D Platformer) A unique side-scrolling game built around a physics-based swinging mechanic. Developed custom swinging system using Unity physics Implemented enemy AI (state-based behavior) Integrated VFX, Spine animations, and gameplay systems Focused on responsive movement and performance 🎣 Angler’s Journey A complete game built from scratch, showing my ability to design, implement, and finish core gameplay systems independently. Designed and implemented full gameplay systems independently Built core mechanics without prior professional experience Demonstrates strong problem-solving and self-learning ability 🌌 Take Me To Elysium (Capstone Project) A fully developed game created without AI assistance—pure engineering and research. Built complete system architecture Integrated UI, animations, and VFX Focused on clean implementation using Unity documentation 💡 Why clients work with me: I focus on game feel, not just code I can take a system from idea → fully working feature I understand both technical implementation and player experience I communicate clearly and can work long-term 🤝 Let’s work together I’m open to indie projects, startups, and long-term collaborations. If you need a developer who can build solid gameplay systems and make your game actually feel good, send me a message. *Unity *C# *Game Development *Gameplay Programming *Artificial Intelligence (Game AI) *2D Game Development *3D Game Development *Mobile Game Development *Game Mechanics *Debugging *Performance Optimization *Spine Animation *UI Development (Unity) *Physics Systems *Animation Integration I don’t just write code—I make sure your game feels good to play.

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

I started my C# career writing diagnostic software for nuclear power plants. Reliability there wasn't a feature. It was the baseline. That habit never left me, and these days it goes into my Unity work: small, focused tasks, full games, and everything in between. 7 years of C#. PC, mobile, VR. I can jump into an existing project, own a standalone system, or take your idea or GDD all the way to a working MVP: planning, architecture, gameplay, UI, integrations, optimization, testing, and builds you can actually play. 🔹 SOME THINGS I'VE BUILT • Godly Survivors, an action roguelite released on Steam. I designed and developed it solo, including custom progression, enemy AI with dynamic difficulty, and runtime world generation. I owned its design and development from first concept to launch. • Expanded a 12-level 3D educational game for kids with new arcade mechanics, story progression, and supporting systems. • Developed VR/XR apps for Meta Quest and Apple Vision Pro with live 360° video, streamed content, and backend integration. • Built mobile games and simulators featuring boat physics with water dynamics, time-stop puzzle mechanics, REST APIs, Firebase, and monetization. • On one optimization job, I cut an app's build size by 5x. I genuinely enjoy profiling and hunting down CPU/GPU bottlenecks. 🔹 WHAT I CAN DO FOR YOU • Build your game from start to finish: indie titles, MVPs, and vertical slices. • Design and code gameplay systems: combat that feels right, enemy AI, abilities, inventory, economy, progression, and save systems. I lean on data-driven configs so designers can tune things without touching code. • Help on the design side too: core loops, balance models, docs a team can implement without guessing, and custom Unity Editor tools when a workflow needs one. • Take over or extend an existing project: new features, bug fixes, refactoring, third-party integrations, and gameplay or UI polish. • Profile and optimize for PC, mobile, and VR. • Handle backend and platform integrations: Firebase, REST APIs, Addressables, IAP, ads, and the SDKs your project needs. 🔹 HOW I WORK Clear milestones, risks raised early, and playable builds throughout instead of one big reveal at the end. AI speeds up implementation and testing; I do the thinking, shape the architecture, and make the final call. You get honest progress updates, documented changes, and code the next developer won't curse at. I care about the product, not just the paycheck. Details matter to me. Whether it's a focused fix, an indie MVP, or something bigger (AAA too, assuming you bring the studio 🙂), send me your idea, GDD, current build, or task description, and I'll help turn it into a working result.

Unity Developer specializing in building polished 2D/3D gameplay systems with C# and Unity. Strong experience developing core game mechanics, UI/UX systems, animation (Mecanim & Rigging), and multiplayer features using Unity Netcode. Hands-on with monetization systems including In-App Purchases and Ads Mediation. Worked on multiple complete game projects, from prototyping to release, focusing on clean architecture, maintainable code, and smooth player experience. Comfortable with asynchronous programming, game data persistence, and performance debugging across devices. Fast learner, detail-oriented, and reliable — I focus on delivering stable, scalable solutions that help projects reach completion.

I'm a Senior Unity engineer with 10+ years of commercial development experience across games, mobile, desktop apps, and production systems. My strongest area is game development, especially when the work is technically complex, crosses multiple systems, or needs to be delivered without breaking the rest of the product. I work across gameplay systems, UI flows, tools, client/server logic, launchers, and production fixes. I can take a project from scratch to a playable MVP or vertical slice, continue building an existing product, or step into a messy codebase and move it forward safely. I'm comfortable taking ownership, solving hard problems, and keeping delivery practical and focused. I also have experience coordinating development teams and building AI-assisted workflows and autonomous agents that reduce manual work and help speed up delivery. Quality, responsibility, speed and real progress matter to me. If you need a senior Unity developer who can build, debug, stabilize, and handle production support, I'm a strong fit.
