What I'm looking for

I’m looking for a role where I can modernize .NET platforms into cloud-native microservices, build high-performance APIs, and strengthen CI/CD and observability—collaborating closely in Agile/Scrum teams on mission-critical systems.

I’m a Senior Full Stack .NET Developer with 10+ years of experience designing, developing, and deploying scalable enterprise web applications across Banking, Financial Services, Insurance, and Healthcare.

I lead modernization efforts—decomposing legacy monoliths into cloud-ready microservices and upgrading platforms to .NET 10 and modern JavaScript stacks. I’ve implemented distributed caching, event-driven systems, and API optimization to improve latency, reliability, and deployment outcomes.

I’m also deeply hands-on with cloud-native engineering and delivery: Azure DevOps CI/CD, containerization with Docker, Kubernetes orchestration, and observability with Datadog/Grafana/Splunk. I build secure integrations and enterprise authentication using Keycloak and Okta while collaborating across product, architecture, QA, and Agile/Scrum teams.
