Software Engineer
3+ years building production systems across enterprise SSO, real-time IoT pipelines, and offline-first mobile. I deliver end to end — domain modeling, Django and Node backends, React and Flutter clients, Linux deployment — with a focus on civic technology that improves government transparency in the Philippines.
About Me
I'm a Computer Engineer by training, based in the Philippines, building web, mobile, and IoT systems end to end — from domain modeling through to Linux deployment.
Since July 2026 I've been a full-stack developer at VirtualSpotter, building FitForms, an AI-assisted forms platform for fitness studios. Alongside it, I'm the sole engineer on Fireplace, a freelance build of a map-first condo marketplace for the Philippines on Next.js and Supabase.
Before that, at Komunidad, I developed and maintained production-grade web applications using Django, implemented secure enterprise authentication (SAML SSO), and architected real-time services using MQTT across Linux-based cloud environments.
Earlier, as a Science Research Analyst at MMSU, I built GIS-enabled data platforms mapping renewable energy assets across 100+ sites, and deployed containerized applications using Docker and Kubernetes to support research workflows.
On the side, I build civic technology tools — Bantay Gusali and Surbol PH — Flutter apps designed to improve government accountability and infrastructure transparency in the Philippines, along with Leanmetry, a local-first fitness app.
Experience
- Building FitForms, a multi-tenant SaaS forms platform where fitness studios and franchise groups create intake forms, waivers, and signups, match them to their brand, and embed them on their own sites.
- Built Claire, an AI assistant on the Vercel AI SDK and Convex Agent that creates and edits forms from chat; every change is a proposal the user approves inline, with a diff and single-change undo/redo.
- Built auto-theming from a studio's website, Facebook page, or YouTube channel via Brandfetch behind an SSRF-guarded fetch, plus a theme editor that lets a franchise HQ lock its brand across locations.
- Built the public-form embed system (popup loader, iframe events, frequency caps, deep links); merged 64 pull requests in three months with a 95% test coverage floor, axe-core checks, and five UI languages.
- Sole engineer on a map-first condo marketplace for the Philippines, taking it from a static client prototype to a Next.js 16 and Supabase platform with consumer, agent, broker, and admin portals.
- Made PostgreSQL Row Level Security the authorization boundary across 150+ additive migrations, with database functions owning listing moderation, broker approvals, and a full audit trail.
- Shipped Google Maps search with viewport re-query and URL-synced filters, a leads pipeline, realtime messaging, tour scheduling, and CSV/XLSX bulk listing import.
- Built a 400+ suite test harness (unit, live RLS, integration, and Playwright E2E with axe accessibility checks); resolved production latency caused by a Vercel/Supabase region mismatch.
- Built and maintained production Django applications; reduced API response times through query optimization and caching.
- Implemented SAML SSO across internal applications, consolidating authentication into a single identity provider; configured AWS IAM Identity Center for local and staging environments.
- Architected systemd-managed MQTT and SFTP services feeding a Django ingestion pipeline.
- Provisioned and managed Linux VMs across staging and production; delivered features on a weekly Agile sprint cadence.
- Built full-stack Django and React applications that improved data accessibility for research workflows.
- Designed and shipped a GIS web application (Node.js/Express, Leaflet, MySQL) mapping renewable energy assets across 100+ sites; live at arec.mmsu.edu.ph.
- Containerized and deployed applications with Docker and Kubernetes on on-premise Linux servers.
