About Me

I build real-world business systems, modern full-stack applications, and search-focused websites that solve practical operational problems and create measurable value.

My work blends:

  • full-stack development
  • SEO-focused website strategy and implementation
  • internal workflow and business systems
  • infrastructure and technical operations
  • security-minded engineering
  • e-commerce systems and reporting

I work across practical production environments like PHP, MySQL, cPanel, XAMPP, IIS, Apache, and hosted internal systems, while also building on modern stacks like Next.js, TypeScript, Prisma, PostgreSQL, Tailwind CSS, Redis, BullMQ, and Vercel.


What I Work On

  • Build internal systems for approvals, workflows, inventory, quotations, reporting, and daily operations
  • Ship full-stack apps with strong UX, real data workflows, and production-minded architecture
  • Create SEO-focused websites with stronger content structure, technical improvements, and search visibility thinking
  • Handle backend logic, deployment, hosting, integrations, maintenance, and troubleshooting
  • Turn messy business requirements into usable systems teams can actually rely on

Project Highlights

Instead of relying on third-party GitHub stat cards that break randomly, here’s a cleaner snapshot of the kind of work I am actively building:

  • Building flagship full-stack systems with production-minded architecture
  • Shipping internal business software with role controls, reporting, workflow logic, and operational depth
  • Growing deeper across web development, infrastructure, security, and technical operations
  • Expanding into SEO-focused web builds and search visibility work through practical projects
  • Continuously improving repositories so they look and feel closer to real products, not just student demos

Featured Repositories

Featured Projects

CrickInPhSEO

A search-focused cricket website project built to improve discoverability for cricket-related searches in the Philippines. This repo reflects hands-on SEO work around structure, keyword targeting, on-page optimization, technical cleanup, and building a cleaner search presence through a real shipped website.

Repo: CrickInPhSEO

Vertex-POS

A production-minded point-of-sale system designed around real business workflows instead of student-demo features. It pushes into inventory movement, operational controls, receipts, analytics, reporting, permissions, and retail logic that make it feel closer to an actual product.

Repo: Vertex-POS

VitaVault

A health-tech full-stack platform for personal health records, secure data organization, caregiver-aware workflows, and modular product growth. One of my strongest product-focused repos, built to reflect deeper backend ambition and real-world platform thinking.

Repo: VitaVault

TrailPulse

A full-stack hiking trail discovery and planning platform with authentication, calendar integration, background jobs, saved planning workflows, and a modern product-minded architecture.

Repo: TrailPulse
