About Me

I'm Simón Escobar, a senior full-stack developer with years of experience designing and shipping production-ready web applications. I specialise in the JavaScript/TypeScript ecosystem — from pixel-perfect React frontends to robust Node.js backends and real-time APIs. I care deeply about clean code, performance, and developer experience.

Based in Cali, Colombia, I work exclusively with US-based clients in their timezones, delivering at 40–60% less than US agency rates — without compromise on quality.
