About
I'm a full-stack developer and freelance digital illustrator who thrives at the intersection of logic and creativity. I build intelligent systems that solve real problems — from computer vision automation in hardware-software integration to AI-powered educational platforms — while maintaining a sharp eye for design and user experience.
Beyond the code, my background in project management, data science, and machine learning allows me to architect systems that handle complexity: whether that's designing scalable data pipelines, training and deploying predictive models in production, or untangling patterns in large datasets. I'm equally comfortable translating business requirements into technical specifications as I am designing modular visual systems.

Tallyx: Blockchain-Verified Credit Ledger
Sari-sari store owners track customer credit (utang) in notebooks, so balances are easy to dispute and payments hard to prove. On the team building Tallyx, a mobile receivables ledger with optional Stellar/Soroban verification, I built the payments flow: payment-method support, mobile payment screens, a SecureStore wrapper, and backend payment routes and services with integration tests. It shows full-stack mobile work across Expo, an Express/Drizzle/PostgreSQL API and a blockchain-backed data model.
Treaty: Secure File Handover for Freelancers
Freelance creatives risk handing over final files before clients pay. On the team building Treaty, a secure file-handover platform, I built the project creation flow with multi-media upload, automated image and video watermarking, token-based share links, and asset and annotation retrieval. It shows backend feature work in a NestJS + Next.js monorepo with media processing.

Building Outside the Box: How a Web Developer Managed a Hardware Prototype
Mar 7, 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.
Project Management/LeadershipFrom the Sidelines to the System: Building the Animolympics Live Results Platform
Feb 17, 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.
Web/Mobile ApplicationMore Than a Title: A Journey of Becoming
Feb 17, 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.

Sagup Negros Website UI Concept
Food waste mitigation initiatives often struggle to communicate their impact and coordinate resources through fragmented digital channels. I designed a website UI concept for Sagup Negros to centralize their mission and streamline community engagement. This prototype focuses on an intuitive user journey that balances educational content with actionable ways for users to contribute to local food sustainability.

Cocotel Website Revamp
The original Cocotel website featured a dated interface that struggled to reflect the brand’s evolving identity and meet modern user expectations. I developed a modernized UI prototype that prioritizes intuitive navigation and sleek visual storytelling to enhance the digital guest experience. This project aligns the platform with current industry standards, ensuring a seamless and engaging interface for a broader audience.

PharmaFetch UI Design
Standard delivery interfaces can be overwhelming and difficult to navigate for users with diverse physical or cognitive needs. I designed PharmaFetch, a UI/UX prototype that prioritizes accessibility to simplify the process of ordering and delivering essential medicines. This project demonstrates how inclusive design can remove digital barriers, ensuring a seamless and reliable experience for all users.
