What I'm looking for

I seek senior roles building cloud-native, secure microservices with strong DevOps/CI/CD practices, collaborative teams, and opportunities to mentor and modernize systems.

I am a senior backend engineer with over 17 years of experience building and maintaining high-performance, cloud-native systems. I specialize in microservices architecture, Kubernetes, and modern Java development, and I actively contribute to open-source projects.

My accomplishments include migrating legacy applications to Java 21 and Spring Boot 3.x, implementing enterprise authentication (OAuth2, SAML, ADFS), integrating object storage with MinIO, and modernizing CI/CD with GitLab CI/CD and ArgoCD for GitOps-driven deployments.

I am a collaborative technical leader who mentors junior engineers, promotes pair programming, and drives observability and database modernization efforts to deliver secure, scalable, maintainable solutions.
