What I'm looking for

I seek a senior mainframe development or production-support role where I can apply COBOL/DB2 expertise, improve processes, work in collaborative Agile teams, ensure production stability, and grow into technical leadership.

I am a Mainframe developer with over 10 years' experience building and supporting enterprise mainframe applications using COBOL, JCL, DB2, IMS, UNIX and related tools. I work across the full SDLC (Waterfall and Scaled Agile/Scrum) and focus on reliable, production-ready delivery.

I have provided production support, root-cause analysis, and software development for multiple clients, creating and maintaining WDI maps, scheduling with Tivoli/OPC and CONTROL-M, and using tools such as SPUFI, QMF, ENDEVOR, Changeman and OMEGAMON. I write and review BRDs and TRDs, design and execute unit/UAT test plans, and manage package promotions between environments.

I collaborate closely with stakeholders, SMEs and architects to prioritize requirements, drive process improvements, and ensure quality releases. I am results-oriented, experienced in monitoring and incident resolution, and focused on mentoring team members while delivering measurable improvements to production stability.
