## whoami

> Fullstack developer from the Philippines with 7 years of experience shipping web apps, APIs, and enterprise software. I've worked with international clients across satellite tracking, audit management, digital asset management, and fintech. Currently building software for internet service providers — customer portals, network monitoring, and automated alerting systems. I am open for freelance hire in the Philippines and globally.

## currently_building

> ISP management platform — building customer portals, real-time network health monitoring, automated billing, and alert systems for internet service providers.

## interests

> I gravitate toward projects at the intersection of finance, productivity, and developer experience — things like SelfOS, a personal dashboard I'm building that combines budgeting, journaling, and habit tracking into a single MCP-powered interface. Outside of that, I explore cybersecurity and electronics as side interests.
