What I'm looking for

I’m looking for a role where I can support and modernize IBM i applications (RPGLE/SQL) and interfaces, handle SDLC work, and help with migration and maintenance—available immediately.

I build and maintain IBM i (AS/400) applications using RPGLE, RPG Free, CL, SQL, and DB2—supporting homebuilding and manufacturing platforms while handling ongoing maintenance, interface work, and ad hoc reporting.

At Newmark Homes, I developed custom programs using RPGLE, CLP, JSON/XML, and SQL, and used change control to promote code to production. I also supported interfaces like CRM and Appwright/ERP solutions to retrieve and export data, while creating and maintaining technical documentation for systems configuration and troubleshooting.

I’ve also led migration and modernization efforts—translating iSeries Cobol/RPG to Snowflake in remote engagements—and supported enterprise insurance/claims applications through code review, integration, regression testing, and UAT-to-production deployments.
