Tim Building Systems That Scale
8 years of coding, 4 years professionally. I'm a self-taught developer from Germany who loves building complex backends and scaling them to millions of users. From solo projects to leading teams, I'm at my best when I'm solving hard technical problems and making sure everything runs smoothly.
01. About Me
I started coding back in 2017 as a hobby, and it quickly became my main thing. I'm a self-taught developer who loves building systems that actually work under pressure. My sweet spot is where backend architecture meets real-world scale.
These days, I spend my time leading teams and making sure we're building things the right way. I'm less about just "managing" and more about ensuring clean code, solid tests, and systems that don't break when traffic spikes.
I'm based in Bochum, Germany, and when I'm not diving into .NET internals or tweaking Svelte components, I'm usually tinkering with open-source projects or exploring new ways to make systems more observable.

03. Experience
Senior Full Stack Developer & Team Lead
@ Opera SystemI'm currently leading the engineering team here, where I built the entire .NET Core backend from the ground up. I handle everything from real-time messaging using SignalR to complex task orchestration with custom AI agents. I also set up our entire observability stack with Grafana and OpenTelemetry because I like knowing exactly how our systems are performing in real-time.
Senior Full Stack Developer
@ ReelShort / RedReelsBuilding an engaging short-form video platform focused on mini-series content. Working across the full stack with C# backend and Next.js frontend, implementing series management, video discovery features, and high-engagement interactive elements.
Senior Full Stack Developer
@ SteamAnalytics (Octo)Built a comprehensive Steam game analytics platform with .NET 9 backend and Next.js frontend. Implemented clean architecture with CQRS, time-series data with TimescaleDB, message-driven processing with RabbitMQ, and real-time analytics dashboards. Project discontinued after MVP as the product complexity exceeded the company's strategic interests.
Lead Developer & Interim Product Manager
@ Tingo.aiI was the first developer on the project and built the entire initial platform solo. As we scaled to millions of users, I moved into a lead role, helping grow the team while keeping our AWS infrastructure from melting under massive traffic spikes. I spent a lot of time bridging the gap between our marketing goals and technical reality, ensuring we stayed stable as we grew.
Contributor & Platform Developer
@ alt:V PlatformI started out in QA but couldn't stop building things on the side. After open-sourcing a complete roleplay gamemode that got community adoption, I joined the core team to contribute directly to the multiplayer framework itself. It was a great deep-dive into core systems and multiplayer architecture.
04. Featured Projects
An omnichannel messaging platform where I got to build my dream backend. I used .NET Core with SignalR for real-time speed, and RabbitMQ to keep things moving in the background. It features custom AI agents that can jump in to help humans or take over complex tasks entirely.

- RabbitMQ
- OpenTelemetry
I built the first version of Tingo by myself, and it blew up faster than we ever expected. I had to learn on the fly how to scale AWS infrastructure to handle millions of users while building out the team. It was a wild ride of late-night scaling and setting up the kind of monitoring that keeps you sane.

Get In Touch
I'm always looking for interesting projects where I can lead a team or dive deep into backend architecture. If you're building something cool (or just want to talk about .NET and Svelte), I'd love to hear from you.
