6+ yrs · C++ / C# · real-time, full-stack & cloud

Software engineer & solution architect.

I architect and ship full-stack products and the low-latency, networked systems and game engines behind them. From server-authoritative netcode to cloud on AWS, I own the design end to end and keep it reliable under real load.

04Services

Available for contract & freelance.

I take on focused engagements where deep systems experience moves the needle, and I can start immediately.

01

Real-time & netcode systems

Multiplayer architecture, server-authoritative replication, interpolation and latency hiding, and the reliability layers that keep them stable under load.

02

Engine & tooling

Custom engine work, editor tooling, build/CI pipelines, and platform ports across Unity, Unreal and bespoke C++ engines.

03

Full-stack delivery

End-to-end product work: native clients, .NET Core / Python services, and AWS, owning architecture from first commit to release.

Available now. Open to contract & full-time, UK + remote.
