About

I’m currently working with a small team (<10 people) on a multi-tenant web application — a customer self-service portal used daily by tens of thousands of energy customers across multiple brands (like eon, vw and prokon). My role is frontend and mobile app development, as well as ai-development integration. Key Highlights: • Multi-client architecture supporting different clients and providers • Customer self-service for contracts, meter readings, payments, and documents • Mobile-first, PWA-enabled design • Internationalization via Lokalise • Component-driven architecture with PrimeReact + custom library Tech Stack: React 19 · TypeScript · Vite · Vike (SSR) · PrimeReact · TanStack Query · Zustand · Storybook · Capacitor · Playwright · GitLab CI/CD · Sentry · Elastic APM Besides my main work, I occasionally collaborate with friends on side projects — from a tour guide management platform to a mobile health app — exploring new ideas and technologies along the way.
