What I'm looking for

I seek a collaborative team where I can build secure, scalable web applications, work on challenging backend/frontend problems, and grow into technical leadership.

I am a full-stack developer with over six years of experience building and maintaining scalable web applications, primarily using Ruby on Rails. I deliver reliable, well-tested features and adapt quickly to new technologies like ReactJS when needed.

At Safelink I contributed 800+ successful merge requests spanning features, bug fixes, and automated tests, directly improving product stability and user experience. I designed and implemented multi-factor authentication systems (SMS, authenticator app, email) to strengthen security and compliance.

I led implementations that improved client-facing configuration and flexibility, including site branding configuration, multi-group membership functionality, and enhanced Terms & Conditions application across the platform. I also built export capabilities for Chronology Events (PDF & DOCX) and developed ingestion for Expert Witness Format (EWF) files.

I graduated with a BS in Computer Science from the University of the Philippines Los Baños and have a track record as a collaborative team player focused on problem solving, performance optimization, and delivering high-quality product outcomes.
