Jeffer Barragán

Senior full-stack engineer and tech lead with 8+ years building high-scale web products alongside world-class engineering teams. I set clear, measurable goals, grow the engineers around me, and ship technical work that moves the business — combining engineering depth with a designer's eye for UI decisions that actually work for users. Currently leading frontend for a suite of crypto applications at Mercado Pago, Mercado Libre's fintech arm.
