Message

At GDC Systems, I develop and deploy Azure Function Apps integrated with the VTEX e-commerce platform, and use Claude Code for development, testing, and engineering automation. I’m also developing AI agents with the OpenAI SDK in Python and Java.

At IBM / Kyndryl, I worked on mission-critical middleware platforms for Banorte, resolving major incidents and automating IT operations. I also contributed to architecture design, risk mitigation, and Agile squad leadership.

Across my work with IBM middleware, I’ve defined reference architectures and configuration standards, and worked on high availability, tuning, and troubleshooting. My experience also includes designing and deploying integration flows on Kubernetes and building cloud applications on IBM Cloud, AWS, Heroku, and GCP.
