Jorge Cortés · Software & DevOps Engineer

About me

Systems engineer with 15+ years of experience in backend development, cloud (AWS) and CI/CD. I help companies automate their delivery, move their infrastructure to code and build reliable backends and APIs.

Throughout my career I've worked with international clients and contributed to products that real users rely on: integration platforms, inventory systems, pharmacovigilance platforms and applications for the financial sector.

I believe great software starts with clear communication and honest expectations: when you work with me, you always know where things stand. Great software isn't built alone; it's built together, for everyone.
