What I'm looking for

I'm looking to continue developing and maintaining mainframe applications, contributing to program enhancements, testing, code analysis, and reliable delivery in collaborative development environments.

I've developed and maintained COBOL mainframe applications for Bankinter and Santander through LCG XAD, using JCL, CICS, DB2, and Endevor. My work includes new program development, application enhancements, deployment packages, and analysing batch programs in LIVE environments.

I've created JCL, performed functional testing in PRE and DEV environments, and supported the evolution of existing banking programs. I use Jira, ServiceNow, Remedy, Confluence, and SourceTree to manage development, requests, and version-control activities.

Earlier, I investigated bugs and delivered new features in mainframe applications, while also building a web application with JavaScript, HTML, CSS/Sass, and React.
