At Digis, I developed and maintained eight backend microservices for a CRM platform powering next-generation car wash systems. I implemented business logic and asynchronous messaging, and integrated three external payment providers: CardKnox, DataCap, and OpenEdge.

Across roles at JetBeep, Luxoft, Brightgrove, and others, I’ve designed backend APIs and modernized legacy .NET applications. My work has included integrating factory equipment through OPC UA, connecting enterprise systems such as SAP, and improving application security.
