About Sven

I started programming at the age of 11 – first small games, then anything that sparked my curiosity. This curiosity led to my profession: Today, I am a Software Architect and Game Developer with over 8 years of full-stack experience, pursuing a degree in Computer Science at HHU Düsseldorf alongside my work.

I support companies in four areas:
- Game Development – Unreal Engine 5, C++ and Blueprint. As Lead Game Developer, I was responsible for the open-world multiplayer game HeistLine; under my label MayStudios, I develop my own games and Unreal plugins.
- AI Integration & Agentic Automation – AI workflows, AI agents and process automation (including n8n) as well as the meaningful integration of AI into existing company processes.
- Full-Stack Web Development – Java/Spring Boot, Node.js, React/TypeScript, PostgreSQL. As a Software Architect at LikeTik (TikTok partner), I was responsible for the architecture and backend of an AI-powered social commerce platform.
- Mobile Development – including with Flutter, covering store release and monetization.

What you get from me: clean, maintainable architecture (Hexagonal, Microservices, Clean Code), fast and pragmatic implementation from idea to release – and someone who combines technical depth with real product thinking. Whether it's a game, web app, mobile app, or AI automation: I reliably bring projects to completion.
