Introduction
I’m a Mainframe System Engineer for keeping complex IBM Middleware environments running smoothly, securely, and at peak performance. Over the years, I’ve specialized in managing and optimizing systems built around IBM CICS Transaction Server, IBM MQ, and CICS Transaction Gateway (CTG). My work focuses on ensuring the reliability and scalability of core banking and enterprise platforms that run on z/OS Parallel Sysplex architectures. I excel in fast-paced, high-pressure environments where critical thinking, deep technical expertise, and effective problem-solving make all the difference.
