What I'm looking for

I'm looking for an opportunity to join a team of passionate builders to design and craft sophisticated solutions for the problems that matter.

At esurance.ch, I architected and built a serverless Lead Management System that processes millions of daily insurance leads and sped up related business processes by three orders of magnitude.

I also co-developed a Radix-based UI kit adopted across 10+ applications, reducing component duplication by about 90% and new screen delivery time by about 60%. I designed a modular frontend architecture and Storybook playground that helped the team move its prototyping loop from weeks to days.

At froach, I led the design and delivery of a microservice platform. I built a headless CMS and Storage service, integrated Keycloak for platform-wide authentication, and devised an Apache Kafka orchestration strategy.

I co-founded a venture and built a canvas-based task management MVP from scratch. Earlier, I developed web applications across healthcare, insurance, and entertainment, including a healthcare statistics pipeline that processed about 100,000 events per day.
