I'm a GTM Engineer. I build the outbound engines behind growth: sourcing and enriching leads, automating outreach with n8n and Clay, and turning the data into decisions.
Based in Bacolod, Philippines. Summa Cum Laude in Computer Science, freelance illustrator on the side.

ICP Content-Engagement Engine
Clients posting on LinkedIn needed to know which of the people engaging with their content match their ideal customer profile. I built a daily pipeline: per-client n8n workflows collect post likers and commenters, deduplicate them against run history, and hand each new engager to Clay for enrichment and LLM classification. A Google Apps Script layer then rebuilds the report tabs, syncs an all-clients master sheet and serves an internal leaderboard, with error alerts and scheduled jobs chained to stay within execution limits.

What if? | Hit Game Predictor
Developing video games is highly risky, making it difficult to predict if a specific combination of genre, console platform, and publisher will resonate with the market and achieve commercial success. As a solution, this project provides a full-stack machine learning web application powered by a Random Forest algorithm trained on historical video game sales data.

Sequencer Monitoring Dashboard
Cold-email campaigns and mailbox health were spread across two sequencing platforms, Smartlead and Instantly. I built a Next.js dashboard that pulls campaigns, warmup health and reply and deliverability stats from both APIs on a 30-minute Vercel Cron, stores snapshots in Supabase and charts them in one place behind company Google sign-in.

GuideU: Chatbot-Enabled Digitalized Student Handbook
The GuideU platform serves as a centralized digital resource for the University of St La Salle, enhancing access to institutional guidelines and student services. By transforming the Student Handbook into an interactive Wiki, coupled with an AI chatbot, it aims to simplify navigation and improve student engagement, ensuring that essential information is just a click away.

All posts →- Building Outside the Box: How a Web Developer Managed a Hardware PrototypeMar 2026I joined Green Module Systems as a web developer. The scope seemed straightforward — build interfaces, write frontend logic, maybe touch some backend APIs if the project called for it. What I didn't expect was being handed a Reverse Vending Machine prototype to build. Not a web simulation of one. An actual, physical machine with a camera, sensors, a thermal printer, and a computer vision model that had to work in the real world. Even less expected was the fact that I'd step up to manage it.
- From the Sidelines to the System: Building the Animolympics Live Results PlatformFeb 2026Photo by: University Student Government | Motivated by the friction of delayed event standings, I self-initiated the development of a real-time web leaderboard for the University of St. La Salle’s largest sports event. While the technical execution—a mobile-first system with a secure admin CRUD panel—was a success, the project's true value lay in the post-mortem. This reflection explores the gap between building a functional tool and achieving institutional adoption, offering an honest look at stakeholder alignment, "on-the-fly" live deployment fixes, and the evolution from a display tool to an operational backbone.
- More Than a Title: A Journey of BecomingFeb 2026Photos by Computer Science Society | From a quiet realization on a bus ride to leading the Computer Science Society through a year of "firsts," my term as Executive President was defined by unexpected growth. This is a reflection on navigating the resistance of leadership—from administrative hurdles to the success of our university’s first-ever Game Jam—and the lessons learned in cultivating a community rather than just managing an organization.
