Message

At Play XD LTD, I define technology strategy and contribute hands-on to Unity games and applications for mobile, PC, web, and VR. I’m currently finalising a VR project in collaboration with Meta.

As Director of Sowinski Software Ltd, I delivered bespoke software and Unity experiences for clients. My work included cloud-integrated systems using Azure and AWS, as well as custom CMS and workflow solutions.

At VSL, I initiated and led development of a Unity-based mobile application, defining its architecture and implementing cross-platform features. I also contributed to improvements in backend services and business systems.

Earlier, I developed software across financial services and legal technology, including a bespoke DynamicMapper framework at Mojo / Life’s Great / Complete Money and integrations and workflow automation at Antony Hodari Solicitors. I’ve also designed personal game projects, including an entity-based framework in C#/.NET for MonoGame/XNA.
