About me

I'm a backend-focused engineer who loves owning systems end to end — from requirement analysis and database schemas to CI/CD pipelines and Kubernetes clusters in production. At Mercedes-Benz R&D I led the backend and DevOps for XOT, a platform used by dealers and workshops worldwide, and conceptualized CARE IT, a carbon-emission tracker that earned a patent.

Today, as a Site Reliability Engineer at Guidewire Software, I work on the availability, scalability and observability of a cloud platform that runs insurance workloads at serious scale.
