At HungerStation (Delivery Hero), I own payment infrastructure for a platform processing about 600K orders a day. I led the migration of the payment core from a monolith to microservices, integrating payment providers and Apple Pay tokenized checkout through gRPC and event-driven architecture.

I built a payment failover and auto-disabling mechanism that raised payment acceptance to 98% while sustaining about 1,000 authorization requests per minute. I also integrated Incognia for geolocation-based fraud detection.

At HungerStation, I designed a Journal service to ingest, reconcile, and synchronize financial journals from external parties. I also own vendor dispute resolution and invoicing for the global finance entity.

Earlier, I migrated users to the Talabat and HomeAway ecosystems at TryCarriage.com and IBS Software, and worked on backend systems at 7NODES, Red Panthers, PIT Solutions, and Centre for Social Computing & Information Society. My projects have included food delivery, vacation rentals, digital telecommunications, and retail investing platforms.
