Software Engineer | C# | Unity | API Integration | Production Development I'm a Software Engineer with 10 years of professional experience developing production software across game development, WebGL applications, multiplayer systems, and internal development tools. Throughout my career, I've worked with startups, independent studios, and international teams, contributing to commercial products from early development to live production. I specialize in understanding existing codebases, implementing new features, fixing complex bugs, and maintaining production software. I can help with: - C# development - SQL - Web Development - Backend Development - Database Design - Unity3D Development - Bug fixing & debugging - Multiplayer integration (Photon, Unity Netcode, PlayFab) - REST API integration - WebGL applications - Existing project maintenance I'm comfortable joining projects at any stage, quickly understanding unfamiliar code, and delivering reliable, maintainable solutions. If you're looking for someone who can extend an existing application, solve technical problems, or help move a project forward, I'd be happy to discuss your project.

I build Unity game systems that are designed to last — modular, data-driven, and easy to extend without touching code. My focus: game systems architecture, ScriptableObject-driven design, interactive and gamified experiences. I've taken projects from GDD to final delivery, handling architecture decisions, client communication, and documentation along the way. Published games on Steam. Delivered client projects in Unity. Currently building a new title with an artist. What you get: Clean, scalable architecture from day one Full project ownership — I don't just build features, I think about the whole system Clear communication and documentation throughout EU timezone, fluent English, available for calls I work on projects that ship. If that's what you're building, let's talk.

WHY WORK WITH ME? • Education: MSc in Software Engineering (FER). • Speed: I use modern "Vibe Coding" workflows (Cursor, AI Agents) for rapid delivery. • Communication: I explain complex tech in plain English. Whether you need a full build, an automation script to save you time, or a consultation to validate your strategy—I am ready to help. Let’s build something future-proof.

With 15 years of professional experience in game development, I specialize in Unity, C#, graphics programming, multiplayer networking, and system architecture. I have a proven track record of leading projects from concept to final release across PC, PlayStation 5, and Xbox Series. My technical expertise includes developing custom rendering pipelines, implementing robust networking solutions, and optimizing performance to deliver immersive and engaging gaming experiences. I thrive in complex, technically challenging environments and am passionate about crafting high-quality interactive experiences. Let’s collaborate and bring your project to life!

I’ve been in game development since 2015, starting as a Unity programmer and expanding into 3D modelling, environment art, and Unreal Engine production over the years. I’ve worked on mobile titles, VR/AR museum experiences, and larger commercial projects—including: Relevant Experience ✔ Lead Programmer & Technical Designer — “Go Home Annie” Demo (Steam Release) I was the sole programmer on this horror title during its Demo phase and collaborated closely with the creator on 3D modelling, environmental design, gameplay systems, and optimization. This project reflects my ability to own an entire technical stack, ensure code quality, and translate vision into a functional product. ✔ AR Developer — “The Silence that Tore Down the Monument” (Europa Nostra Award Winner) I developed the full AR experience. Over the last year, I’ve been deeply exploring UEFN, Verse, systems scripting, UEFN databases, and Creative ecosystem constraints. I’ve built several unpublished prototypes—some small mechanic tests, some larger systems—and released one Halloween-themed map to understand publishing, memory limits, and discovery workflows. My background in Unity scripting and Unreal Blueprint concepts made Verse a natural extension, and I’m now comfortable building: Gameplay systems and interactive logic Data-driven mechanics using UEFN databases Modular and scalable systems designed for iteration Levels that balance gameplay readability, pacing, and performance

My top skills are Gatsby, React, Node.js, Django, Vue, Quasar, React Native, and AWS. Worked on multiple web projects where my role was full-stack developer and quite often I would take the role of DevOps if needed. I am also experienced with Construct 3, Godot, and GMS. I started my career as a game developer, but I always wanted to learn more so my next stop was Web and mobile development. ⭐️ Experience in Web development as: ✅ Front-end developer(jamstack) ✅ Back-end developer ✅ Full-stack developer ✅ DevOps ⭐️ Experience in game development as: ✅ lead programmer ✅ designer ✅ pixel artist
