Rodjean Verzosa

Fullstack Developer · Remote

I design and build reliable web applications end to end — from data models to pixel-perfect interfaces.

About

I'm a fullstack developer with 3+ years of experience shipping production web applications, from early-stage MVPs to systems serving millions of requests a day.

I care most about the seams: clean API contracts, predictable data flow, and interfaces that feel instant. I've spent equal time in React component trees and in database query plans, and I like it that way.

Outside of client work, I contribute to open source, mentor junior engineers, and write about the tradeoffs behind the tools I use.
