Software Engineer
Worked on a project for the Dutch public transportation sector (NS), contributing to an end-to-end solution enabling travel with QR codes instead of conventional tickets.
Digital Ticketing with NS
This was a high-intensity project for the Dutch national railways (NS). I worked on the core services that allowed passengers to travel using dynamically generated QR codes.
The project required extreme precision in handling ticketing state and real-time updates via WebSockets to ensure a smooth gate-passing experience for millions of travelers.
Core Responsibilities
- Built backend and integration components for ticketing workflows.
- Contributed to real-time communication features using WebSockets.
