“Building digital products that bridge the gap between human needs and AI potential.”

Kita Tracker
What started as a simple tool to help my sister manage her small food business has grown into Kita Tracker - a modern inventory management and business analytics platform built specifically for small food businesses in the Philippines. This is my personal startup project that I'm passionate about because I've seen firsthand how Filipino entrepreneurs struggle with tracking inventory, sales, and expenses. The platform combines a full POS system, real-time inventory tracking, and business analytics - all completely free because I believe every sari-sari store, carinderia, and small food business deserves access to professional tools. I'm on a mission to help more Filipino entrepreneurs succeed.

Anaya Care
I am the full-stack developer for Anaya Care, an enterprise-grade care management platform built as a comprehensive monorepo with three interconnected applications: a NestJS backend API with extensive feature modules and dual Socket.IO gateways, a React Native/Expo mobile app with role-based interfaces, and a Next.js web application with comprehensive dashboard pages. The platform features real-time communication, AI-powered care planning with specialized OpenAI services, HIPAA-compliant document management, advanced shift scheduling with GPS tracking, and comprehensive health monitoring to streamline elderly care services.

Build My Wealth: Personal Finance App
As the Lead Mobile Developer & Co-Founder, I built Build My Wealth, a personal finance app featuring a sophisticated offline-first architecture with RxDB and bi-directional CouchDB synchronization. The app uses CRDT-based conflict resolution for eventual consistency, reactive data layer with observables for automatic UI updates, and fully offline-capable financial transaction workflows.

Geriatric Care Solution
I am the full-stack web developer for Geriatric Care Solution, an enterprise-grade geriatric care platform featuring extensive React components, MongoDB models, and custom hooks. This sophisticated application combines cognitive health activities including AI-generated crosswords, sudoku, and paint-by-numbers, family collaboration tools through Family Circles, an AI-powered e-book creation wizard, and comprehensive care management features. The platform integrates dual AI systems (OpenAI GPT-4 + Google Generative AI) for personalized content generation, real-time communication via Socket.IO, and a multi-tier subscription system with Stripe. With extensive admin management capabilities and specialized features for dementia support, it serves as a complete digital care ecosystem for seniors, caregivers, and healthcare professionals.
