What I'm looking for

I’m looking for a role where I can build and ship full-stack features, improve reliability with automated end-to-end testing, and contribute to migrations—working with a team that values performance, security, and clean design.

I’m a Software Engineer focused on building and maintaining enterprise systems that meet real client needs—especially across complex, multi-module codebases. I’ve worked on products including a PMS, EMR, ERP, and a pawnshop management system for a major Philippines pawnshop chain.

I use Next.js and MySQL to deliver reliable functionality, and I’m careful about code quality and security. Through code reviews and automated end-to-end testing with Cypress and Playwright, I identified and resolved bugs while keeping systems stable and performant.

I also completed a full-stack migration for a background check and HR compliance platform, moving from .NET Framework MVC to .NET Core and React. I contributed to frontend development and backend data processing across modules like identity verification, criminal records, drug testing, and ATS integrations.

Earlier, as an intern Software Developer, I supported the development and testing of a school ERP system across the full software development lifecycle. I continue to build outside work too—like Paldoo (POS and inventory management) and a 5S Audit Management System—because I enjoy turning requirements into practical, polished software.
