What I'm looking for

I’m looking to lead backend and API architecture for high-traffic, regulated products—building secure microservices on cloud platforms with strong CI/CD, performance tuning, and team mentoring.

I’m a Senior Back-End Developer with 10+ years of experience architecting and deploying production-grade server-side applications across fintech, banking, and insurance. I specialize in C#/.NET Core, microservices, RESTful APIs, and cloud-native systems—built to handle real-world load and reliability demands.

In my current role, I architect .NET Core APIs and optimize database systems to deliver scalable multi-tenant microservices for a fintech platform, supporting 10,000+ merchants with 99.8% uptime. I improve resilience and incident response by implementing debugging frameworks and resilient architecture patterns, and I secure infrastructure using JWT/OAuth 2.0 to meet fintech regulatory standards.

I lead engineering execution end-to-end: building CI/CD pipelines with Azure DevOps, containerizing services with Docker/Kubernetes, and optimizing performance through indexing, data partitioning, query tuning, and caching. I also mentor teams (6+ and previously 8 developers), enforce Clean Architecture and SOLID principles, and strengthen code quality with thorough testing practices using xUnit/NUnit, Moq, and integration/unit testing.
