I build secure, scalable .NET APIs and multi-tenant applications for banking and automotive operations.

I build secure, scalable .NET applications, from banking microservices at Endava to automotive SaaS platforms used by service centers.

At Endava, I develop and maintain backend APIs for a large-scale banking client, using .NET 8, Oracle SQL, Kafka, OAuth2, JWT, Docker, Jenkins, and Elasticsearch. I improve distributed-service performance through asynchronous processing, implement ECS-aligned centralized logging, document integration contracts, review code, mentor teammates, and contribute to architectural decisions.

I also designed and developed eServiceAuto.ro, a multi-tenant platform that centralizes repair-shop operations, automates ANAF and RAR integrations, and adds AI-assisted document and vehicle-defect workflows. Previously, I built web and mobile applications with .NET, Blazor, DevExpress XAF, and .NET MAUI, while mentoring five developers and working directly with clients on requirements and delivery.
