What I'm looking for

I am looking for a hands-on technical leadership role where I can build scalable systems, mentor teams, and improve processes with strong communication and modern development practices.

I am a software engineer and manager with over 25 years of professional experience, combining deep hands-on technical skills in C++ and Python with proven leadership as a CTO and technical director. I lead by example, delivering core systems and frameworks while mentoring and empowering teams to adopt SOLID principles and Test-Driven Development.

As CTO and co-founder I designed and implemented a multiplayer game framework (Unreal C++ plugin), set up automated CI/CD pipelines, and administered company systems (AWS, GitHub, Atlassian). My work has consistently improved productivity, code quality, and release processes across studios.

I focus on clear communication, knowledge sharing, and building scalable, modular architectures. I seek to bring technical excellence and inclusive team leadership to organisations building complex software and games.
