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.

I am an AR/VR Solution Architect and Idea Generator with 10+ years of hands-on experience creating immersive 3D, AR, VR, and real-time web solutions. My primary value lies in transforming raw ideas into clear, viable, and scalable technical concepts. I generate product ideas, define system architecture, choose the right technologies, and design the overall technical vision that turns concepts into real, working products. I stay personally involved in the most critical parts of implementation to ensure that the original idea is executed correctly and reliably. I specialize in projects where there is no ready-made solution and where strong architectural thinking is required — including AR/VR platforms, interactive simulations, digital twins, product configurators, and experimental real-time 3D applications. What you can expect: • Clear product and technical vision from the very first discussion • Thoughtful architecture built for scalability and long-term use • Hands-on implementation of core and complex components • Direct communication with the person responsible for technical decisions • Production-ready solutions, not just prototypes or demos Core expertise: AR / VR / XR • WebXR, 8th Wall, ZapWorks, Spark AR • Unity (C#): AR, VR, MR applications • AR Foundation, ARCore, ARKit, Vuforia, EasyAR • VR frameworks: XR Interaction Toolkit, VRTK, Oculus SDK Unreal Engine • Unreal Engine 4 / 5 (Blueprints & C++) • Real-time visualization and architectural walkthroughs • Interactive simulations and product configurators • CARLA Simulator for autonomous driving and simulation • Niagara VFX, Sequencer, Metahuman integration Web & Real-Time 3D • Three.js, A-Frame, PlayCanvas • WebGL, GLSL • React, Vue.js • Desktop packaging with Tauri and Electron Backend & System Architecture • Node.js, PHP, Laravel • MySQL, PostgreSQL, MongoDB • Docker, Nginx • API integration and system design How I work: I work directly with clients from the idea stage. I help shape the concept, define the architecture, validate technical assumptions, and personally implement or prototype the most critical parts of the system. My goal is to ensure that the final solution is technically sound, scalable, and aligned with the original vision. Typical use cases: • Turning early-stage ideas into technical concepts and prototypes • Designing architecture for complex AR/VR and 3D systems • Interactive simulations and digital twins • 3D product configurators and visualization platforms • Technical consulting and architecture reviews My goal is to help you move from an idea to a clear, technically grounded solution that can grow into a real product. Feel free to book a consultation to discuss your idea, concept, or technical challenge.
