I am a Senior Frontend Engineer with a decade of experience building scalable, cross-platform applications. Currently at Security Bank Corporation, I drive the development of the bank's Retail Application across Web, Android, and iOS. Specializing in a modern tech stack that includes ReactJS, NextJS, React Native, and TypeScript, my focus is on delivering unified user experiences and highly optimized codebases. As a dedicated problem solver, I recently engineered critical performance enhancements that successfully reduced application load times from 10-15 seconds down to just 2 seconds. Throughout my career, I have seamlessly bridged the gap between complex technical execution and team collaboration. I actively coordinate end-to-end release schedules, ensure deployment compliance, and accelerate team momentum by creating structured onboarding programs for new developers. Before entering the fintech space, I served as a Senior Front-End Web Developer at Ntersol OPC, where I built interactive streaming platforms and complex, data-driven component libraries. My extensive portfolio also features progressive web apps for international identity services and high-traffic e-commerce systems for top-tier brands like Domino’s Pizza PH and Goldilocks. Beyond my daily engineering work, I am a passionate educator and mentor. I have spent years shaping the next generation of technologists as an instructor, workshop speaker, and robotics coach at Dr. Yanga’s Colleges, Inc., regularly training students for national and international competitions. Whether I am architecting robust frontend solutions, mentoring junior developers, or speaking at regional tech summits, I bring a strong blend of technical mastery and collaborative energy to every project I tackle.
