Hey, I'm
Sergio Saucedo
I build
Software Engineer currently contracting for enterprise clients in the automotive sector, leading legacy-to-modern platform migrations with Python, React, Azure, and Kubernetes. Also the founder of ClinicNet, a B2B SaaS serving 120+ dental clinics in Mexico. Previously at IBM, contributing to the Ansible for IBM Z ecosystem and delivering automation workshops to enterprise clients. I like building things that solve real problems — whether that’s a manufacturing system or a WhatsApp appointment reminder.
