Featured Work

Projects that showcase real-world problem-solving and production-ready development

GastoGuard - Personal Finance Tracker

The Problem

Most budgeting tools help you track spending but don't enforce software quality. I wanted to build a finance app that was as reliable as it was useful — with automated testing, continuous integration, and security baked in from day one.

My Role

Solo developer. Architected the full stack, wrote comprehensive test suites with Vitest, convex-test, and Playwright, configured CI/CD via GitHub Actions, conducted an OWASP Top 10 security audit, and shipped as a PWA.

Key Outcomes

  • CI/CD pipeline via GitHub Actions — tests run on every push
  • OWASP Top 10 security audit completed and documented
  • PWA — installable on any device, works offline
  • Real-time financial health scoring algorithm

Backend & Architecture

  • Convex real-time backend with server functions
  • Backend mutation testing with convex-test
  • Real-time financial health scoring algorithm

Kampo Ibayo Resort - Booking System

Full-stack resort booking platform handling real customer reservations and payments for an operating business.

The Problem

A real operating resort needed to replace manual booking with an online system handling reservations, payments, and staff management.

My Role

Lead developer in a 3-person capstone team. Built the customer booking flow, integrated PayMongo payment processing, designed the admin dashboard, and implemented OCR payment verification.

Key Outcomes

  • Real-time availability — eliminates double-bookings
  • Admin dashboard reducing manual work for resort staff
  • 306 commits across the project lifecycle

Backend & Architecture

  • PayMongo payment processing with webhook verification
  • Supabase PostgreSQL database with real-time subscriptions
  • AI chatbot handling 200+ FAQs for customer support

TripSulit - Tour Booking Marketplace

Full-stack tour booking marketplace connecting Filipino travelers with tour organizers — built during my internship at ServeBeez.

The Problem

Filipino travelers had no dedicated platform to discover and book local tour packages, while tour organizers relied on manual processes to manage bookings, payments, and communication with customers.

My Role

Web developer in a 2-person intern team at ServeBeez. Built the full-stack web platform: multi-step checkout with PayMongo payments, real-time messaging, organizer dashboard, admin panel, AI-powered tour search, and 23+ transactional email templates via AWS SES.

Key Outcomes

  • Live production marketplace serving real paying customers
  • AI-powered tour search and trip guide using Claude and Gemini
  • 10+ automated cron jobs for slot holds, reminders, and scheduling
  • Role-based access for travelers, organizers, and admins

Backend & Architecture

  • 28-table production database schema
  • PayMongo multi-gateway checkout (GCash, PayMaya, card)
  • 23+ transactional email templates via AWS SES

About Me

Full-stack developer who ships tested, production-grade applications

I ship production web applications with the testing discipline most senior developers would expect — automated test suites, CI/CD pipelines, and a security audit. All before my first full-time role.

My Journey

During my internship at ServeBeez, I built TripSulit — a production tour booking platform processing real payments. For my capstone, I led development on Kampo Ibayo, a resort booking system serving a real business. Then I built GastoGuard with a full automated test suite and CI/CD pipeline — because I believe if your code isn't tested, it isn't done.

What Sets Me Apart

Most portfolios show projects that work on demo day. I ship projects with automated test suites, CI/CD pipelines, and security audits. I've processed real payments through PayMongo, handled real customer data with proper security, and built systems that real businesses depend on — not just class assignments. I've coordinated with team members, communicated with business stakeholders, and led code reviews — not just written code in isolation.
