// profile

Full-Stack Engineer based in Germany with a Mechanical Engineering background turned software. Two years building and shipping a complete facility-management platform — admin dashboard, NestJS backend, an offline-first React Native app along with AI work. I like turning messy real-world processes into clean and reliable software.

Mobile App · Admin Dashboard · Backend

A production-ready, offline-first facility-management platform that lets field workers run the entire work-order lifecycle — from a phone with no signal to a full admin dashboard.

Admin dashboard in React + TypeScript: 10+ connected modules (users, customers, services, addresses, work orders, reports, schedules and more) with complex modal systems, full CRUD and i18next localization.
NestJS / Prisma / PostgreSQL backend: Automated recurring work-order scheduling via cron processors, holiday detection across 100+ countries, PowerSync sync, JWT auth with refresh tokens and role-based access control.
React Native (Expo) app: PowerSync offline-first architecture with real-time cross-device sync, complete offline CRUD, GPS location tracking and a photo-upload system with an attachment queue.
Cross-platform polish: Light/Dark/System theming with Zustand, AWS S3 photo storage, PDF report generation, time tracking with breaks and multi-worker collaboration.
