Geriatric Care Solution
Lead full-stack web and mobile developer for Geriatric Care Solution, building and maintaining 4 enterprise applications: the main GCS platform, Anaya Care, Care Prints, and For Little Readers. This role involves developing across Next.js web apps, React Native mobile apps, and NestJS backend services. The platforms feature AI-powered cognitive health activities (crosswords, sudoku, paint-by-numbers), real-time communication via Socket.IO, HIPAA-compliant document management, and multi-tier subscription systems with Stripe integration. Dual AI systems (OpenAI + Google AI) power personalized content generation and automated care planning across 9 health domains.
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
Built as part of my work at Geriatric Care Solution, Anaya Care is an enterprise-grade care management platform. I architected this comprehensive monorepo with three interconnected applications: a NestJS backend API (30+ modules, dual Socket.IO gateways), a React Native/Expo mobile app (72 screens with 6 role-based interfaces), and a Next.js web application (94+ dashboard pages). Features include real-time messaging, AI-powered care planning with 9 specialized OpenAI services, HIPAA-compliant document management, GPS-tracked time clock, and advanced shift scheduling with RRule patterns.
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.
