Hello, I'm

Ervin Pangilinan

Full Stack Developer



About Me

I started coding in 2021, turning a hobby into a daily practice. I build reliable, accessible apps and have experience in both solo and team projects. During a full-stack developer job, I worked on different technologies, web architecture, databases, secure authentication, and automated releases. With a Computer science degree, I focus on clean, maintainable code backed by strong fundamentals and teamwork.

What I can do

  • Web Applications

    Web apps in different architectures: static, single‑page, server‑rendered, multi‑page, or hybrid built for speed, accessibility, and SEO.

  • Mobile Applications

    Smooth mobile apps with offline storage, native UI, and safe updates using React Native/Expo.

  • DevOps Basics

    Automated builds and releases (CI/CD), Docker containers, and cloud hosting with basic monitoring.

  • Game Development

    Small 2D games in Unity with simple controls, basic AI, and optimized UI/performance.
