What I'm looking for

I’m looking for a dynamic environment where I can leverage COBOL/DB2, JCL, and CICS expertise to enhance legacy systems, lead reviews, and drive reliable deployments with strong testing and collaboration.

I’m an experienced Systems Engineer with over five years of experience specializing in mainframe technologies, including COBOL, DB2, JCL, and CICS. I focus on turning business requirements into dependable batch and online solutions through strong engineering discipline.

In my current role, I lead code reviews and design walkthroughs with cross-functional teams, while developing and enhancing COBOL programs and JCL scripts. I also support deployment and implementation activities, ensuring changes move smoothly from development through validation.

I’m hands-on with unit testing, debugging, and integration testing to keep systems stable and business-critical. I’ve worked across z/OS environments, handling incident management and ensuring application functionality is verified with clear test documentation.

I’ve delivered impactful enhancements such as updating vendor file naming functionality, creating accurate CICS services, and improving batch automation and file handling. I’m now seeking new opportunities to leverage my technical expertise and problem-solving skills in a dynamic environment.
