About

Who I am

I'm Elmer Sorto, a full-stack developer based in El Salvador with over a decade of experience building production systems — from Shopify storefronts to complex enterprise logistics applications.

Currently working as an IT Analyst at Triton Logistic, where I architect and ship critical apps for CRM, inventory, and invoicing using C#, .NET, SQL Server, and React.

I've built products for clients across Mexico, Chile, Argentina, Spain, India, USA, and Canada. Degree in Systems Engineering from UTEC and a deep passion for open-source tooling.
