About

Engineer. Leader. Builder.

I don't just write code — I design systems, lead teams, and ship products that solve real operational problems.

I got into computer science because of a deep interest in technology and systems — not just how they work, but how they can transform the way businesses operate. What started as curiosity quickly evolved into a passion for building software that replaces outdated manual workflows with scalable digital solutions.

Over the past few years, I've moved well beyond academic projects. I've led cross-functional teams of 15+ developers, shipped production systems used by 30+ organizations, and built custom software for real clients managing operations across multiple locations. My internships at Symph and Orange & Bronze deepened my engineering discipline — from enterprise design patterns to agile workflows in production environments.

I enjoy the intersection of engineering and product thinking — designing architectures that scale, managing sprints and deliverables, mentoring developers, and ensuring that every system I build has measurable business impact. As a co-founder of BANSAG, I'm extending this mission — helping Filipino businesses build their digital identity and systems from the ground up.

Whether it's engineering a scalable backend, leading a sprint retrospective, or advising a client on their digital strategy, I bring the same mindset: build it right, build it to last, and build it with impact in mind.
