About

I am a Mainframe Modernization Engineer currently working at NTT DATA, with experience in COBOL, JCL, DB2, CICS, VSAM, and Unikix rehosting projects. I completed my engineering education with a strong interest in enterprise systems, backend technologies, and large-scale application modernization. My passion lies in solving complex technical challenges and continuously learning new technologies in the banking and legacy transformation domain. At NTT DATA, I have been involved in mainframe rehosting and migration projects, helping move legacy applications from traditional mainframe environments to Linux/Unix platforms using Unikix. I work on analyzing, modifying, and troubleshooting COBOL programs, JCL procedures, DB2 queries, and CICS components to improve application stability and performance. I have collaborated with cross-functional teams in agile environments, strengthening my communication, problem-solving, and teamwork skills while ensuring smooth delivery with minimal downtime. I am currently focused on growing my expertise in Mainframe Modernization, Cloud Migration, and Enterprise Application Transformation. My goal is to build a strong career in large-scale modernization projects while continuously enhancing my technical and leadership capabilities. I am open to networking and opportunities in Mainframe, Legacy Transformation, and Modernization technologies.
