Hey, I'm Zen πŸ‘‹

Full-stack developer working in React, TypeScript and Node, based in DasmariΓ±as, Cavite, Philippines. I build multi-tenant platforms end to end, from the data model to the last hover state, across HR, inventory, education and IoT.

🟒 Open to work.


🧱 What I've Built

Two years at Uzaro Solutions (Nov 2024 – Sept 2026), delivering sprints on 6+ concurrent platform builds and joining client meetings from kickoff to go-live, handover and training.

Project What it is
🏒 HRIS Multi-tenant HR system for Bandai Namco: employee lifecycle, recruitment, payroll, timekeeping with biometric devices, and role/department/organization-scoped access. Deployed to Cloud Run and on-prem Kubernetes with Argo CD.
πŸ“¦ OSPAR GS1-standard inventory system tracking item movement across organizations and departments, from internal transfers to patient usage, with billing and reporting.
πŸ“š ALMA Multi-tenant LMS with tenant isolation, an assessment engine, attendance and gradebook: 3 tenants, 200+ students, 15+ instructors.
πŸ”Œ IoT dashboard Smart door locks, relays and gateways in one React dashboard: real-time control of 50+ endpoints at under 500 ms latency.

Also shipped: hotel reservations, order management, supply chain and project management systems.

🚧 In Development

  • 🏍️ Odoko is an offline-first Android app for Filipino motorcycle riders: a fuel, service and spending logbook with an AI mascot that runs a Gemma 3 1B model entirely on the phone, so nothing leaves the device. Built with Expo, React Native and Kotlin native modules, with the model fine-tuned using Unsloth.
  • 🐀 Peck is a job application tracker and AI resume builder for Philippine job seekers, built as a mobile-first PWA. An LLM fills fixed slots from facts the user confirmed, and a custom validator rejects any line it can't trace back to one.
