Hire the Best Unity Developers
in Poland

I’m a professional Unity Developer with 7 years of experience specializing in mobile games, WebGL optimization, and complex UI/HUD implementation. My skills include: - Advanced UI/HUD design and implementation (UGUI) - Optimization for WebGL and mobile (performance & build size) - ECS/DOTS gameplay development - Multiplayer integration (Photon, HTTP API) - Legacy code refactoring and optimization - Custom Unity Editor tools development Technologies & Tools: - Unity 3D, ECS/Job System, WebGL, Photon - C#, MVC/MVVM - Mobile platforms (iOS, Android) Why choose me? I deliver clean, maintainable, and optimized code. My deep experience in troubleshooting and optimizing legacy Unity projects ensures fast, high-quality results. Let's discuss your project!

🎤As a Unity Developer with 6+ years of hands-on experience, my work spans the full spectrum of development across desktop, mobile, and XR platforms - UI systems, gameplay mechanics, graphics programming, networking, and custom tooling. I've developed projects from scratch, worked on R&D projects with blurry inputs and unpredictable results, and fit into long-term projects with complex codebases where maintainability comes first. I wear many hats and can transform any concept into an interactive and playable form. Beyond Unity, I've expanded into visual programming with vvvv gamma and TouchDesigner, where my experience oscillates between computational and visual and includes audio-reactive and generative systems, procedural mesh generation and mapping of arbitrary computed data on the GPU to arbitrary visual output in general. I bring a multidisciplinary and platform-agnostic approach - my knowledge is domain-wise, not tool-wise. This gives me freedom and flexibility. This freedom and flexibility, combined with deep technical expertise, enables me to solve challenging creative problems with equally creative technical solutions. Core Skills: - ✨ Graphics & Visuals: VFX Graph and Shader Graph, custom HLSL shaders (surface, compute, and geometry), custom render pipeline features - 📱 Platforms: PC, Android, and iOS development with specialized cross-platform optimization - 🥽 XR Technologies: SteamVR, MRTK, XR Interaction Toolkit, Meta XR SDK, AR Foundation, Leap Motion integration - ⚡ Programming: Advanced C# (OOP, low-level optimization, Job System, UniTask, async/await patterns), Python and C++ experience - 🚀 Performance Engineering: Advanced CPU/GPU profiling, mobile-first optimization strategies, platform-specific performance tuning - 🎬 Animation: DOTween, Unity Timeline - 🎨 UI Systems: uGUI framework, custom UI shaders and VFX integration, responsive cross-platform interfaces - 🌐 Networking & Multiplayer: Mirror - 🔊 Audio Systems: Wwise integration, MIDI and OSC integration, real-time audio-visual synchronization - 🎭 Creative Toolkit: vvvv gamma, TouchDesigner, Blender, Figma

Hi 👋 I’m a Unity programmer with 12+ years in game development. I build games from prototype to full release across mobile, WebGL, and PC, and I’m equally comfortable joining mid-project to fix critical issues, optimize performance, or stabilize unstable builds. Whether it’s a hyper-casual prototype, a mid-core RPG, or a multiplayer live-ops project — I deliver clean code, smooth gameplay, and reliable results. 🚀 🔹 What I do best Full-cycle Unity development — take your project from concept and prototype to launch-ready game Cross-platform builds — mobile, WebGL, PC, optimized for performance and memory Multiplayer & live-ops systems — Photon, PlayFab, analytics, monetization, retention improvements Expert bug fixing & optimization — tricky crashes, memory leaks, edge cases, build size reduction Legacy code rescue — stabilize and refactor outdated, messy, or incomplete projects 🔹 Work style Clear estimates and timelines before starting Regular progress updates with measurable results (daily or weekly) Open, fast communication; adapt quickly to feedback and changing priorities Focus on delivering working, polished, release-ready projects 🔹 Why work with me 12+ years in game development (indie & enterprise) Ability to deliver complete games for any genre and platform Clean, maintainable code designed for long-term development Strong debugging & optimization skills — fix critical bugs, improve performance, and reduce build sizes Trusted to rescue mid-project when things aren’t working, without slowing the schedule Clients praise my speed, reliability, and ability to deliver under tight deadlines 🛠 Tech Stack Unity, C#, Addressables, Photon, PlayFab, DOTS, ShaderGraph, Firebase, C++, Ruby, Objective-C, SQLite, IronSource, JSON, Protobuf, dev2dev, Appsflyer, Game Analytics, Tenjin, IAPs, ByteBrew, Yandex SDK, React, JavaScript, Google Play Services, Zenject 🧠 Selected Results PUA — Date Game & Love Stories: Created a custom scenario tool (cut content time 2h → 10min), implemented AI bots, fixed major production issues Idle Spellbound Mage RPG: Reduced build size by 75%, enabling a successful WebGL port without losing features Nanomedix: Transformed unstable, incomplete project into a release-ready product through stabilization, optimization, and feature expansion Zombie Shop: Solved elusive critical bugs QA couldn’t reproduce, stabilizing a high-profile release Merge Islanders: Enhanced core systems & performance; updates doubled revenue according to publisher 💬 Let’s talk Need help with full-cycle Unity development, optimization, bug fixing, or launching a complete game? I’m available for consultations, quick fixes, or long-term collaborations — let’s make your project a success.

Hello! I'm an experienced Unity developer, I'm mainly a programmer, making mechanics and using my knowledge to fix bugs and issues in the projects I work on, usually as a main developer. On top of that, I have a lot of experience with visuals, so creating 3-D assets is no issue for me, same with 2D assets (especially UI), animations and VFX. I'm good with optimizing projects, got experience with publishing and I worked in quite a few teams so I understand the importance of communication. Please let me know if you're interested in my skillset. My skills: 1. Unity developer for 5+ years: -Experience with making mobile games, implementing ads and in-game purchases -Experience with photon engine -Experience with SignalR -Experience with Firebase -Experience with Json 2.C# programmer for 5+ years 3. Blender 3D artist for over 5 years 4. VFX artist in Unity 5. Animator in Unity In conclusion, I'm capable of developing the entire project by myself in many cases but I got a lot of experience working in teams. When it comes to my salary I usually charge 25$-35$/h, I'm fine with fixed prices. With regards, Maksymilian
