Summary
Mainframe Developer at Tietoevry Banking in Master Data Management, with a diverse background in sales, marketing, and healthcare. Skills include COBOL, SQL, PL/SQL, Easytrieve, CICS, VSAM, DB2, JCL, TSO/ISPF, agile, and Scrum. As well as coordination across banking value chains (web services, frontend, customer teams) to deliver functional value, optimize processes, and drive business outcomes. Highlight includes building a banking feature for expanded business code reporting, which I helped design, code and launch on time after full testing to improve regulatory compliance to open new revenue streams. I am passionate about large-scale impact projects, currently optimizing Tietoevry's core banking platform with CPU/MIPS-conscious development to minimize costs.
