About Anthony KOZAK

I'm a senior full-stack developer and game engineer with over 16 years of professional experience delivering scalable, high-performance digital solutions across web, mobile, VR, and console platforms. My work spans custom software engineering, interactive 2D/3D game development, mobile app architecture, and real-time 3D applications for brands and studios worldwide.

The Ubisoft Years

The defining chapter of my early career was joining Ubisoft, one of the world's largest game publishers. I contributed to AAA development pipelines at both the Montreal and Lille studios, which gave me an inside view of how large-scale game production is structured — from pre-production concepting through to platform certification and live-service support.

At Ubisoft Montreal, I worked on Eagle Flight, one of the studio's first VR launch titles for PlayStation VR. Building a full-scale AAA VR game in 2016 meant solving problems nobody had solved before at that fidelity: comfort-first locomotion systems that didn't make players sick, rendering pipelines optimized to maintain 90fps on the PS4's fixed hardware, and interaction design for an embodied experience where every frame of latency is felt rather than seen. It remains one of the most technically demanding projects I've worked on.

At Ubisoft Lille, I contributed to Rabbids Coding, an educational game teaching programming concepts to children through the Raving Rabbids characters. The project won the Educational Game of the Year 2020 at the Games for Change Awards — a recognition that meant a great deal, because the design challenge was genuinely hard: making abstract computational thinking concrete, fun, and accessible to players as young as six, without ever letting the pedagogy get in the way of the game feel.

Building on the Unity Asset Store

Alongside studio work, I built a parallel practice publishing professional tools on the Unity Asset Store. The first asset started as an internal tool I built for my own projects — a mobile and desktop camera controller that handled all the edge cases that off-the-shelf solutions missed. I packaged it, documented it properly, and listed it. The response from the community was immediate: developers had the same problem, and a well-crafted solution was worth paying for.

That first success funded the next asset, and then the next. Today I publish over ten commercial plugins — including Touch Camera Pro, Home Designer, Floor Plan Designer, and Tutorial Engine — used by thousands of developers worldwide. Publishing on the Asset Store taught me something that pure client work doesn't: you only discover how robust your code really is when strangers with wildly different project setups start hitting edge cases you never imagined. Every support ticket is a free code review. The discipline of writing for a public API — clear naming, stable interfaces, comprehensive docs, demos that actually work — made me a better developer across every other context.

The Freelance Evolution

Leaving AAA employment to go fully independent was a deliberate choice. Studios offered stability, but freelancing offered something more valuable at that stage of my career: variety. In a single year I could work on a VR experience for a luxury brand, a mobile strategy game for an indie studio, and a web backend for a game publisher's live events team. Each project brought different constraints, different teams, and different problems to solve. That breadth is now one of my most useful professional assets.

Over sixteen years I've shipped over 50 projects for clients including Meta, L'Oreal, TBWA, and Ankama, spanning VR experiences, interactive installations, mobile games, and full-stack web applications. Today, Exoa operates as a focused boutique practice: I take on a small number of engagements at a time, which means every client gets genuine senior attention rather than being handed off to a junior team.

Based between the United States and France, I bring a global perspective to every project. My approach combines clean architecture, performance optimization, and rapid iteration — whether building from scratch or joining an existing team, I focus on writing maintainable code that ships on time and continues to work long after the contract ends.
