Jacques "Jack" Leemans

Founder, Technical Director and Software Engineer

Hi, I’m Jacques Leemans, founder and technical director at XGameDev.

I’m a software engineer with more than 20 years of experience across apps, games, backend APIs, and production systems.

As a Certified Unity Expert Programmer with more than 13 years of hands-on Unity and C# experience, I focus on building reliable interactive products for games, simulations, education, and technical workflows.

My work covers the full development lifecycle, from early technical planning through implementation, deployment, optimisation, and long-term support.

I have deep experience with game engines, physics, mathematics, content pipelines, publishing, distribution, and the practical realities of shipping software with client teams.

At XGameDev, my role is to help teams make sound technical decisions, reduce delivery risk, and turn complex interactive product requirements into maintainable software.
