At Coopemédicos, I supported internal financial systems end to end, from user-reported incidents and root-cause analysis through fixes and documentation. I migrated core reconciliation procedures from legacy Oracle Forms code into stored PL/SQL packages, reducing monthly bank reconciliation time from about 60 seconds to about one second.
I also built the cooperative’s Statement of Financial Position in Excel to replace manual consolidation of system reports, and re-engineered source reports to run in seconds within PL/SQL-only constraints. I developed automated Oracle data pipelines and repaired and extended an ASP.NET system that generated XML files for SUGEF.
As a Freelance Developer, I currently handle client incidents and deliver database solutions using Oracle PL/SQL, Oracle Forms and Oracle Reports. I’ve also migrated electronic invoicing for a client and implemented invoicing for a Guatemalan company; personal projects include an Oracle production-style home lab and AWS demos.
