What I'm looking for

I'm looking for hybrid, on-site, or remote opportunities where I can lead applications, IT operations, systems integration, and technology projects while connecting business needs with reliable technical solutions.

I've supported 100+ critical applications at Santander Mexico, resolving 1,500+ incidents and service requests while improving production stability, availability, and operational processes.

Most recently, I managed IT at Hacienda El Campanario, coordinating enterprise applications, infrastructure, vendors, and technology projects. I designed a custom access-control solution using Python, Tkinter, SQLite, PDF generation, and QR codes, while supporting SAP Business One and infrastructure migration stabilization.

Across software development, application support, and IT operations roles, I bridge business requirements with technical delivery—from solution design and integration through testing, release validation, production support, and continuous improvement.
