What I do now

Architecture that still respects the interface.

Most of my work lives between frontend architecture, product delivery, and developer experience. I like untangling messy systems and turning them into calmer, faster teams.

How I lead

I stay close to the code. I help teams set standards, reduce rework, and make better decisions earlier, especially when performance, accessibility, or architecture are on the line.

Outside the sprint

I co-organize ReactJS Colombia, write about DX and frontend workflows, and keep learning while working remotely from Medellin and on the road.

Writing

Practical writing for developers building real products.

I mostly write about developer experience, React, TypeScript, testing, and the workflows that help teams ship cleanly. Some posts are published in Towards Dev, others on Medium.
