About

I am a dynamic and innovative programmer with a strong foundation in C++ and Java, and a proven track record of identifying and resolving performance issues in complex systems. With a decade of experience, I have honed my skills in requirement gathering, analysis, design, development, implementation, testing, integration deployment, documentation, and maintenance of applications, with a particular focus on automation.

I am a versatile problem solver with extensive experience in IBM Mainframe environments and banking systems, specializing in performance analysis. Recently I developed a web-based monitoring application for a banking system, showcasing my programming prowess and commitment to driving automation initiatives. I thrive in challenging environments and enjoy tackling unprecedented issues while collaborating with teams.
