🚀 About Me

🇬🇧 EN — Senior Software Engineer with 25+ years of experience, leading distributed engineering teams at Claro El Salvador (América Móvil) and co-founder of Idear, where I build Gibbor — a multi-tenant SaaS ERP with full electronic invoicing (FEL/DTE) for Salvadoran SMBs. I believe in domain modeling first, the right tool for the context, and infrastructure built to professional standards — even when the team is two people and a dream.

🇸🇻 Versión en Español

Ingeniero de Software Senior con más de 25 años de experiencia, liderando equipos distribuidos en Claro El Salvador (América Móvil) y co-fundador de Kodear, donde construyo Gibbor — un ERP SaaS multi-tenant con facturación electrónica (FEL/DTE) completa para las PyMEs salvadoreñas. Creo en el modelado de dominio primero, en usar la herramienta correcta para el contexto, y en construir infraestructura con estándares profesionales — aunque el equipo sean dos personas y un sueño.
