What I'm looking for

I’m looking for a senior role where I can modernize critical systems across Java and mainframe platforms, lead technical delivery and mentoring, and build high-quality, well-tested services with strong architecture and engineering ownership.

I’m a “Distinguished Senior Software Engineer” with extensive experience across both Distributed and Mainframe platforms. I bring deep expertise in systems analysis and design, data modeling, database design, coding, refactoring, testing, debugging, deployment, technical engineering, architecture, and consulting.

In my recent roles, I’ve supported and maintained legacy translation software written in C++ while also developing robust Java back-end applications using object-oriented design patterns. I build and validate with comprehensive unit test suites (JUnit5, Mockito), aiming for “100% code coverage,” and I provide “24/7 primary on-call support” for critical transportation systems on z/OS and CICS.

I’ve also led modernization and delivery for enterprise systems—designing and deploying Spring Boot J2EE macroservices/microservices, handling migrations through Git/Jenkins pipelines, and improving security (e.g., resolving Log4J vulnerabilities by converting to Logback). I’m at my best when mentoring engineers, running thoughtful code reviews, and using Agile and Waterfall methodologies to turn complex requirements into maintainable, reliable software.
