At Bill Consulting GmbH, I built and shipped Youvia CRM, a mobile-first Progressive Web App used by youvia AG’s field sales coaches in Switzerland. It supports appointments, customers, orders, tasks, and visit reports.

I designed the CRM’s Express 5 API over Airtable, with session login and PostgreSQL persistence. I also generated TanStack Query hooks and Zod schemas from one OpenAPI spec.

At Bill Consulting GmbH, I also made a Supabase time-tracking dashboard for the team.

In my projects, I’ve shipped B2G Pomodoro, an installable offline productivity app, and Talksy, a real-time chat app for iOS and Android. I also built patient and caretaker apps for CardioGuardAI that stream sensor data and flag cardiac risk with an ML model.
