Jeo

Software Developer — Graphic Designer

About Me

I'm a Full-stack software engineer based in Davao City, Philippines — building mobile and web apps with React Native, Flutter, Next.js, Svelte, and AstroJS on the frontend, powered by Node.js, Firebase, MongoDB, and cloud infra on AWS, GCP, and DigitalOcean. I ship faster and smarter by weaving AI tools like Claude, GitHub Copilot, and Gemini into my dev workflow — from code generation to debugging to architecture decisions. I move fast without breaking things: cutting feature rollout times, squashing auth bugs, and stabilizing codebases teams were afraid to touch.
