Custom Unity Game Development

From prototype to shipped product — I build games that perform, feel great, and reach players on the platforms they use.

Full-Cycle Game Development

Whether you need a complete game built from scratch or a specialist brought in to accelerate an existing project, I bring 16 years of production experience across mobile, PC, console, and VR platforms. My work spans AAA (Eagle Flight VR and Rabbids Coding at Ubisoft) through to indie and client-work titles across genres: puzzle, strategy, action, simulation, and educational games.

I work primarily in Unity, covering everything from architecture and core systems design to gameplay programming, UI/UX implementation, performance optimisation, and platform submission. I can engage as a sole developer on smaller scopes or as a technical lead integrating with your existing team.

Platforms I ship to: iOS, Android, Windows/Mac/Linux, Meta Quest (standalone VR), WebGL, and Nintendo Switch.

Game Architecture and Technical Direction

Good architecture is invisible to the player but transformative for the team. Early decisions about scene management, save systems, state machines, data-driven content pipelines, and UI frameworks determine how fast you can iterate and how stable your builds are under pressure.

For clients who already have a team, I offer technical direction engagements: a defined period where I review your codebase, identify architectural risks, propose solutions, and mentor your developers on implementation.

Game systems I have deep experience with include: camera systems, input handling, UI frameworks, serialisation and save systems, procedural generation, and online leaderboards and matchmaking backends.

Platform Submission and Live Operations

Shipping is a skill in itself. Platform submission — App Store, Google Play, Meta Quest Store, Steam — involves navigating review guidelines, certification requirements, age ratings, privacy policies, and store listing optimisation. I've been through this process more than twenty times.

Post-launch, games need maintenance: bug fixes, OS compatibility updates, new content patches, and analytics-driven optimisation. I offer retainer-based live operations support for shipped titles.

Frequently Asked Questions

What size projects do you take on?
I work on projects ranging from two-week prototypes to multi-year development contracts. The key factor is clarity of scope — a well-defined project of any size is manageable. I typically prefer engagements of at least one month.
Do you work with existing teams or only solo projects?
Both. I've worked as the sole developer on indie titles and as an embedded specialist within teams of 20+. I adapt to your workflow — whether that's Jira, Linear, Notion, or a shared Google doc.
Which Unity versions do you support?
I work with Unity LTS versions: 2022.3 LTS and Unity 6 (6000.0 LTS) are my current primary targets. I can maintain legacy projects back to Unity 2019 if required.
What are your rates and availability?
My day rate varies by project type and duration. Please contact me for a quote — I provide estimates after a free 30-minute discovery call where we scope the project properly.
How much does custom game development cost?
Day rates for experienced Unity developers range from $500 to $1,500 USD depending on scope and complexity. I provide fixed-price quotes for clearly scoped projects and time-and-materials rates for open-ended engagements. A free 30-minute discovery call lets me scope the project accurately before committing to a number.
How long does it take to build a mobile game?
A polished mobile prototype takes 4 to 8 weeks. A complete mobile game with progression, monetisation, and store submission typically takes 3 to 9 months depending on scope. I use milestone-based delivery so you see working builds at regular intervals throughout development.
Can I see examples of your previous game work?
Yes. My portfolio at exoa.dev/work includes shipped games across mobile, PC, VR, and web platforms. Notable projects include Rabbids Coding (Ubisoft, iOS and Android) and Eagle Flight (Ubisoft Montreal, PlayStation VR). I can share additional references relevant to your specific genre or platform.

What Clients Say

"Anthony is one of those rare developers who over-delivers and knows how to adapt to the concrete needs of projects. Each time, he adapted to the existing code, took the initiative to improve weak points that were causing issues, all while staying on time and on budget."
