What I'm looking for

I seek roles where I can modernize legacy systems, lead cross-team technical projects, and build integrations bridging mainframe and cloud-native services.

I am a senior mainframe developer with extensive experience designing, implementing, and maintaining core banking systems. I lead cross-system development projects, build developer tools, and create integrations that modernize legacy infrastructure while ensuring operational stability.

At Bank Leumi I spearheaded key initiatives including an Eclipse-based IDE rollout for Natural developers, Git integration for Natural libraries, automated mainframe-to-Git synchronization, and migrations from Adabas to DB2/Oracle/ODS using CDC. I also develop RESTful microservices and utilities in COBOL, REXX, Natural, Python, and Node.js to bridge mainframe data and modern services.

I bring a background in full-stack and front-end development, hands-on NOC support experience, and formal education in business administration and information systems, which helps me align technical solutions with business needs and lead complex, cross-functional efforts effectively.
