Work
I present each project according to its real status: commercial product, controlled demonstration, public architecture showcase, or historical production work.
Founder and commercial products
Founder-led commercial product
A governed engineering-to-turnover readiness platform that connects issued revisions, package impact, evidence, blockers, independent review, and durable Release, Hold, or Escalate decisions.
Climate and public-sector SaaS
A multi-tenant planning workspace for organizing Local Climate Change Action Plan sections, evidence, actions, monitoring, revision history, accountability records, GeoJSON layers, and export-ready draft packages.
Private commercial SaaS
A private multi-tenant campaign-operations platform for Philippine campaign geography, field coordination, lawful operational contacts, volunteers, events, incidents, area-level sentiment, election-day aggregates, dashboards, imports, and governed exports.
Technical demonstrations and earlier systems
Industrial data diagnostic
A read-only diagnostic that reconciles archived logical-line records with live Plant 3D P&ID-linked pipeline objects and exposes drill-down evidence, drawing traceability, and bounded review queues.
Distributed systems showcase
A bilingual healthcare information-system showcase demonstrating an appointment-to-invoice event flow across Next.js, Node.js, Spring Boot, PostgreSQL, MongoDB, Redis, Kafka-compatible messaging, GraphQL, and Docker.
Historical public-sector platform
An integrated platform developed for the Philippine Department of Transportation's Public Utility Vehicle Modernization Program, covering transport cooperatives, HR, payroll, procurement, inventory, franchises, communications, and reporting.
Historical enterprise application
An enterprise human-resource information system covering employee lifecycle, payroll, attendance, assets, disciplinary actions, benefits, government contributions, and reporting.
Turnover Ledger predecessor
The earlier engineering-platform foundation that evolved into Turnover Ledger, demonstrating dynamic datasheets, asset lifecycle information, estimation, inventory, verification, multi-tenancy, permissions, auditing, and exports.
