What I'm looking for

I’m seeking senior individual-contributor or tech-lead roles, on-site or hybrid in Luxembourg or remote with US or international companies. I’m particularly interested in developing my skills in LLM and AI tooling, agent orchestration, and integrating AI into applications.

At Caya, I was responsible for architecture, maintenance, and delivery across customer-facing and back-office applications. As Front End Lead, I worked on technical solutions and processes supporting Product OKRs, alongside hands-on engineering and team development.

Earlier, I developed web and mobile products at Caya and Storecast GmbH, and built a real estate booking system at Optylon. I’m interested in bringing my frontend experience to applications integrating AI and LLM tooling, including agent orchestration.
