Jan 2026 — Present- Multi-Project Full-Stack Development : Led feature development across three production platforms (Medilo, CourtHub, DokuVault) using Next.js, NestJS, and Supabase within an Nx Monorepo, delivering AI document intelligence, payment systems, government permit workflows, and offline-capable PWA features.

Projects
CourtHub PH
Mar 2026A sophisticated multi-tenant SaaS platform engineered to streamline sports facility management for Customers, Tenants, and Superadmins. I spearheaded the development of the Superadmin Dashboard and architected a secure, isolated data environment within an Nx Monorepo. To ensure production-grade reliability, I integrated Paymongo for automated payments and configured Resend as a custom SMTP provider for Supabase, guaranteeing 100% deliverability for transactional emails. I also optimized the Docker build pipelines to significantly reduce deployment overhead on GCP.
Green’s Compugadgets — Tech Hub
Feb 2026A high-performance e-commerce catalog and custom PC builder designed for a computer supply center. I built this using a headless architecture with Sanity CMS to allow for dynamic, real-time inventory management. The frontend features a responsive, sleek interface optimized for both gamers and office professionals, providing a seamless browsing-to-inquiry experience.
InternPal - Smart Internship Tracker & AI-Powered Journal
Dec 2025A smart internship tracker and AI-powered journal built to streamline the professional growth journey. Using React and Supabase, I developed a centralized platform for logging daily learning entries and tracking application statuses. The system focuses on organizational efficiency, helping students and interns maintain a structured record of their career milestones and interview feedback.
Chickify
Aug 2025A modern landing page and administrative dashboard developed for a local agricultural supplier in Bantayan, Cebu. I built a responsive, high-conversion interface designed to showcase fresh produce and manage local farm inventory. To ensure long-term scalability, I architected the frontend to be backend-agnostic, preparing the system for a seamless future integration with a Django REST API.
RemindCare+ Web
Mar 2025A comprehensive healthcare management dashboard designed as a companion to the RemindCare+ mobile ecosystem. I engineered this platform to allow medical professionals to efficiently manage patient records and schedule medication reminders in real-time. By leveraging Firebase for data synchronization and Node.js for the backend, I created a reliable bridge between clinical oversight and patient adherence.
E-Commerce
Nov 2023A modern e-commerce platform built to demonstrate a complete shopping lifecycle, from product discovery to secure checkout. I focused on robust relational database design using MySQL and PHP, implementing features for dynamic cart management, user authentication, and a clean, navigable UI that mimics industry-standard shopping experiences.
Photofolio
Jan 2023A minimalist, high-performance gallery platform built to showcase my professional street photography. I developed this project with a focus on optimized image delivery and a "content-first" UX, ensuring that high-resolution captures load quickly without compromising visual quality. It serves as both a technical portfolio and a creative archive for my photography work.
