## Founding Engineer at Forgent

Oct 2025 – present · full-time

I build the AI agents that find tenders on EU portals, draft the bids and check them for compliance, and the platform they run on. Together they take over about 80% of the manual work in a German public tender bid.

I also lead our security work: ISO 27001 certification, EU hosting, independent penetration tests, and a hard rule that customer data never trains our models. AI agents already triage our security findings, and AI-driven penetration testing is next.

## Software Dev Engineer Intern at AWS

Mar 2025 – Sep 2025 · internship

Built a predictor for the core capacity of the EMR clusters behind S3 Express One Zone metering and shipped it to production regions. Metering costs fell by about 65%, and cluster run times stayed predictable.
