Meet The Team

David

Director and Principal Unity Engineer

ArchitectureOptimisationMobile Porting

David ensures your game doesn’t just work - it scales. Specialising in high-performance architecture, he solves the hard technical problems: thermal optimisation, memory management, and large-codebase architecture.

Adam

Lead Unity Engineer

Gameplay MechanicsAIPrototyping

Adam bridges the gap between code and design. While David handles the engine architecture, Adam focuses on “Game Feel” - ensuring combat is snappy, controls are responsive, and the core loop is fun.

The Extended Squad

Need to scale up? We've got a tight contractor bench of named senior Unity developers, UI/UX artists, and backend engineers we trust. We bring them in only when project scope justifies it. Always senior. Always vetted. Never juniors hidden behind a senior pitch.

Testimonials

Java to Unity rebuild

“Seeing Nub running on PC, iOS and Android from a single project was a real moment for us.”

Read full quote

“Nub is our baby, an isometric puzzle game we originally wrote in Java, and we always felt it deserved a bigger audience. We brought in Ocean View Games to rebuild it in Unity, and they did a fantastic job. They took our original code and rebuilt the whole game from the ground up, keeping every puzzle mechanic exactly as we made it while properly rethinking the controls for touchscreens. Seeing Nub running on PC, iOS and Android from a single project was a real moment for us. They were brilliant to work with, and I'd jump at the chance to work with them again.”

Embedded game development

“I can say with full confidence there would be no Domi Online without their expertise.”

Read full quote

“Initially hired David to review code for the game at a very early stage and was blown away by his abilities and after a round with the board we hired David as lead developer for the project. He brought with him other developers who also did great work and I can say with full confidence there would be no Domi Online without their expertise.”

Educational app development

“David is very patient and has great communication.”

Read full quote

“David is very patient and has great communication. He is an appropriately skilled freelance Unity developer who understood our project goals from the beginning and worked with us diligently throughout our slow-burn design process. I am pleased that we chose David to develop version 2.0 of our Vocab Builder. Thanks David!”

Frequently Asked Questions

We offer both models depending on the project. For well-defined scopes (like porting a game or building a prototype), we can provide a Fixed Price quote. For ongoing development, co-development, or projects with evolving requirements, we work on a Time & Materials (Hourly/Daily Rate) basis with clear weekly reporting.

You own the bespoke work we create for your project, assigned to you upon final payment. Pre-existing tools and frameworks remain ours and are licensed for use within the delivered project. We do not hold your code hostage. We only reserve the right to display the work in our portfolio (unless we have signed a strict NDA).

Yes. A large part of our business is Staff Augmentation. We can slot our Senior Unity Developers directly into your existing Jira/Slack workflow to help you hit a deadline, optimise performance, or clear a backlog of technical debt.

Yes. OVG has a small senior core team, but we can scale delivery through a trusted network of contractors and specialists we have already worked with on real projects.

Yes. For fixed-price projects, we typically require a deposit (usually 25-50%) to schedule resources and begin development. The remaining balance is paid upon the completion of agreed milestones (e.g., Alpha Delivery, Beta Delivery, Final Gold Master).

We provide a standard 30-day Warranty Period after the final delivery. During this time, we will fix any critical bugs or crashes related to our code at no extra cost. For long-term support (Live Ops) beyond this window, we offer monthly retainer packages.

Yes. While we are a UK-based studio, we work with clients globally and can accept payment in USD, EUR, and GBP via bank transfer.
