Things I've
Built.
// 4 projects — production apps, not tutorials
PulseCheck
Full-stack uptime monitoring platform that continuously checks the health of web services and APIs. When a service goes down or responds too slowly, PulseCheck detects the issue immediately, opens an incident, and notifies your team via email — built for developers who need reliable visibility without enterprise-grade overhead.
CodeSnap
Modern web app that lets developers save, organize, and share code snippets with beautiful syntax-highlighted screenshots. Think of it as a personal snippet library that generates social media-ready code images using the same engine that powers VS Code.
Juvelink
Full-stack case management system for juvenile justice workflows with role-based access control and secure session authentication. Integrated an RFID hardware system (ESP32 + RC522) to track equipment location and assign staff maintenance responsibility — built for government facility deployment.
FigurineZ
Centralized platform for buying, selling, and trading figurine collections with real-time bidding. Built with WebSockets for live auction updates so collectors can bid and transact without page refreshes.
“Four apps shipped.
Zero tutorials.
This is what self-taught looks like.”
Hey, I'm
Rainier.
// Self-taught fullstack developer from the Philippines — started with CS50x and CS50P, fell deep into code, and never came back up.
// I care about the full stack: the logic underneath, the interface on top, and the tiny details most people scroll past.
// When I'm not building, I'm learning. When I'm not learning, I'm breaking things on purpose to understand why they work.

Let's build
together.
Open to full-time roles, freelance, and meaningful collabs.
If you're building something interesting — I'd like to hear about it.
