I'm leading end-to-end quality assurance for LIBRA ERP and INVO at Integrated Digital Systems, testing across web, desktop, iOS, and Android.
I've designed high-coverage test matrices that reduced post-release defects by over 30%, while using SQL Server and SQLite to diagnose complex enterprise bugs. I validate RESTful APIs in Postman and combine Ranorex with AI tools to expand edge-case coverage quickly.
Before QA, I managed 10 IT engineers supporting 42 nationwide branches, 1,000+ PCs, and 800+ active users. I also built and maintained 163 high-availability examination lab workstations and network infrastructure at SABIS.
