What I Build

Reliable systems for work that cannot stay vague.

  1. Multi-Tenant SaaS and Workflow Platforms

    Backend systems that coordinate organizations, users, roles, operational workflows, notifications, reporting, and shared web/mobile clients.

  2. APIs and Third-Party Integrations

    REST APIs and integration layers for external services, identity, payments, KYC, AI-assisted workflows, property data, storage, and enterprise systems.

  3. Legacy Modernization

    Incremental framework upgrades, architecture improvements, workflow refactoring, and safer migration of mature systems without discarding proven business behavior.

  4. Quality and Delivery

    Automated tests, contract documentation, focused regression coverage, debugging, and practical collaboration with distributed engineering, product, QA, and operations teams.

Selected Case Studies

About Me

Backend depth, full-stack range, and a long view of the work.

I am a software developer from Davao City, Philippines, with more than 10 years of professional experience across PHP, Laravel, JavaScript, and .NET projects.

My strongest work is on the backend: shaping APIs, modernizing legacy applications, improving complex workflows, integrating external services, and making systems easier to test and maintain. I also work across React, Vue, and server-rendered interfaces when a project requires full-stack delivery.

I currently work with Scopic Software in distributed international teams and am exploring senior remote opportunities where I can contribute to long-lived products, backend architecture, and reliable delivery.
