What I'm looking for

I seek backend or platform roles focused on enterprise modernization, reliable systems, mentorship, and CI/CD-driven delivery in collaborative teams.

I am a senior software engineer with deep experience designing, developing, and maintaining large-scale enterprise applications across distributed and mainframe environments. I specialize in Java, Spring Boot, microservices, and enterprise modernization, and I have delivered systems for financial, insurance, transportation, and retail domains.

I provide technical leadership, mentor engineers, and drive code quality and reliable deployments using CI/CD and testing best practices. My accomplishments include leading a major FedACH modernization, implementing Spring Boot migration and security fixes, and supporting mission-critical z/OS/CICS operations with 24/7 on-call responsibility.
