About Me

I'm Emmanuel Luján Ríos, a Software Developer and Consultant based in Guadalajara, México. I hold a degree in Computer Systems Engineering from Instituto Tecnológico Superior Zacatecas Sur.

My practice focuses on critical transactional infrastructure, decoupled enterprise e-commerce (SAP Commerce, MedusaJS, commercetools), and resilient full-stack systems where uptime, scalability, and consistency are non-negotiable.

My engineering philosophy is built on structural solidity and zero shortcuts: clean architecture, SOLID principles, API-first headless architectures, and modular code designed to handle high-concurrency workloads reliably.
