What I'm looking for

I'm looking for Senior Front-end or Senior Software Engineer roles, fully remote across LATAM, the US/Canada, and Europe, or local opportunities in Colombia. I'm especially interested in checkout, e-commerce, platform, or AI-tooling-forward teams.

At DEUNA, I ship new payment methods for the one-click checkout, including Apple Pay, and overhauled analytics tracking to support accurate funnel analysis. I also built Claude Code agents and shared workflows for repetitive engineering tasks.

At Mercado Libre, I co-led the MercadoShops v2 migration and owned key parts of its rearchitecture and rollout, including cross-frame integrations connecting the merchant editor and preview. Earlier, I built a delivery truck routing module for Muni Tienda, with order-grouping logic and printable warehouse PDFs.
