🟢 Open to Engineering Manager / Senior EM opportunities — SaaS/PaaS product companies (fintech, marketing tech, health tech, hospitality tech), México / Remote


Sobre mí · About Me

ES | Ingeniero de software y líder técnico con 16+ años construyendo plataformas financieras que procesan cientos de millones de operaciones al día. Mi enfoque está en hacer equipos más efectivos: combinando liderazgo humano con automatización inteligente para eliminar fricción, acelerar entregas y mantener sistemas críticos funcionando sin interrupción.

"Engineering leadership no es solo escribir mejor código — es hacer que el equipo entero sea más efectivo."

EN | Engineering leader with 16+ years building financial platforms processing hundreds of millions of operations daily. My focus is making teams more effective: combining human-centered leadership with intelligent automation to remove friction, accelerate delivery, and keep critical systems running without interruption.

"Engineering leadership isn't just about writing better code — it's about making the entire team more effective."

ES | Actualmente en búsqueda de mi siguiente rol como Engineering Manager / Senior Engineering Manager en una empresa de producto (SaaS/PaaS) — fintech, marketing tech, health tech o hospitality tech — con people management real. Basado entre CDMX y Querétaro, abierto a remoto.

EN | Currently looking for my next role as Engineering Manager / Senior Engineering Manager at a product company (SaaS/PaaS) — fintech, marketing tech, health tech, or hospitality tech — with real people management scope. Based between Mexico City and Querétaro, open to remote.

Mi enfoque de liderazgo · My Leadership Approach

ES | Lidero con claridad, confianza y sin miedo a preguntar. Mi trabajo no es tener todas las respuestas — es construir un entorno donde el equipo las encuentre más rápido juntos. Diagnostico los problemas preguntando: ¿proceso, personas o tecnología? Casi siempre son los primeros dos — por eso invierto en DevEx, no por la automatización, sino para liberar a la gente buena. Me mido por si mi equipo crece, entrega y duerme bien.

EN | I lead with clarity, trust, and a low bar for asking questions. My job isn't to have all the answers — it's to build an environment where the team finds them faster together. I debug by asking: process, people, or technology? Most of the time it's the first two — so I invest in DevEx not for automation's sake, but to unblock good people. I measure myself by whether my team is growing, shipping, and sleeping well.
