Message

At Globe Telecom, I introduced reusable AI harnesses for the full software development lifecycle, from specification analysis and story creation through development and testing.

At Samsung Research Philippines, I architected and developed a distributed automated testing web application that saved KRW 48B in hardware and licensing costs in 2024. I also led a team of five building its Python/Django backend and ReactJS/Next.js frontend.

Earlier, I built a Java Spring Boot training management application at WeServe Systems International, Inc. and developed C software for embedded and telecom systems. My work has included AI-integrated development workflows, API standards, and CI/CD automation.
