Top SchoolJohan Gustafsson is a seasoned C#/.NET senior developer with 16 years of experience building and operating regulated online gambling platforms across multiple European markets.

As a former systems architect and partner at WebPrefer, he led integrations for major operators and implemented high-availability database solutions and replication strategies. Johan is also an active open-source contributor to the Stride3D game engine, improving rendering, shader compilation, and Vulkan reliability—an unusual cross-pollination that informs his systems-level thinking.

His combination of regulated-market compliance experience and low-level performance tuning makes him particularly strong at reliable, auditable financial systems.
