About Me

Senior Software Engineer who does front-end and back-end web development and with 5 years of experience building iOS and Android applications. Has been awarded the 2022 Outstanding Rookie Award by the current employer for being an outstanding performer, and for making immediate impacts on projects and deliverables, going above and beyond what was expected, despite being a fresh graduate at the time. Former Google Developer Student Club Lead, a position given by Google to outstanding students with excellent leadership skills once a year. Founded a student organization, Google Developer Student Club PHINMA UPang, that successfully organized multiple events that teach Google developer technologies. Been the resource speaker at tech events. Proficient in implementing Modular Domain Driven Design (Modular Architecture + Clean Architecture + Domain-Driven Design) and best development practices. Diligent, committed, and can work independently but works best with a team where ideas are shared and tested.

On July 23, 2020, I was one of the 24 students in the Philippines selected by Google to be the Google Developer Student Club Lead for our respective campuses. I joined an amazing community of student leads who will be representing hundreds of colleges and universities across the globe. I believe that technology can do extraordinary things for the world, and I have taken on the responsibility to help students grow as developers and empower these students to impact their communities with technology. Through this experience, not only did I leave a legacy of impact, but also grew as an individual and contributed in a meaningful way to the greater developer ecosystem.

On August 29, 2020, I founded Google Developer Student Club PHINMA UPang. Powered by Google Developers, it is a group of students from PHINMA University of Pangasinan whose aim is to bridge the gap between theory and practical application for student developers. Together with the 1,266+ other GDSC chapters in 106 countries around the world, it is part of a global community that is supported by Google Developers. GDSC PHINMA UPang is also the only university-wide organization in PHINMA UPang that is officially recognized by Google. This community that I started successfully organized multiple events that helped aspiring developers get to know and learn the different Google developer technologies available to them.
