Message

At Stefanini on the CitiBanamex project, I maintain mission-critical banking systems through COBOL code changes, root cause analysis, and bug fixes. I also coordinate and implement production releases through ServiceNow.

Previously, as a COBOL Developer Divestiture at Stefanini, I modified COBOL components and control scripts, implemented functional changes, and supported SIT and UAT testing.

At CENIDET, I designed and implemented hard and fuzzy clustering algorithms in C#, using parallel computing to optimize massive data processing. My work also included experimental testing and computational model analysis.
