About

I’m Michael Jönsson, a Principal Online/Network Programmer with more than 30 years in software development and over 20 years focusing on C++. I have a strong track record in real-time systems, networking, and scalable architectures across gaming, telecom, and backend platforms. For the last 6+ years I’ve worked with Unreal Engine 4.27 and Unreal Engine 5.x, doing multi-layer game development and hands-on development in Unreal Engine 5.7 on personal projects. I specialize in designing and building performance-critical systems with emphasis on stability, scalability, and maintainability. I enjoy technical ownership, mentoring developers, and steering architecture decisions. I’m passionate about strategy games and system design, and I’m currently developing a turn-based strategy prototype in Unreal Engine 5.7, focusing on grid-based gameplay, AI systems, and tactical decision-making.
