I build products from zero to revenue

Stuck build? Runway shrinking? No senior owner? Bring me in. I make the CTO calls and write the code. I ship TypeScript, Go, Three.js, AWS/SST, and AI agents in production. Your code must still make sense in six months.

14 Years Shipping Code

I started coding at 12. Since then I shipped WebXR, old Laravel apps, serverless SaaS, internal tools, and infra that wakes you at 3am. I work across the stack. I am an IHK-certified Fachinformatiker.

Zero to users

Startup CTO Who Shipped

I took several products from blank repo to real users. Some missed. Both teach the same lesson: ship the right thing, skip the wrong work, and keep moving while the brief changes.

Serverless & Containers

Cloud Native on AWS

I build serverless-first on AWS: SST, Lambda, DynamoDB, EventBridge. I use containers when they fit. I write most work in TypeScript and Go, and use Elixir when it fits the problem. Infra lives in code.

Live systems

AI Agents in Production

I run agents in my own business every day: lead gen, code review, ops chores. They call real APIs and have guardrails. If one fails, monitoring tells me within an hour.
