$ cat mission.txt

My professional career began in Colombia, where I gained foundational experience working with COBOL mainframes and AS400 migrations — developing a strong understanding of mission-critical systems that require the highest levels of reliability.

I subsequently transitioned into IBM middleware, spending nearly three years at IBM, where I designed integration architectures and mentored development teams.

Currently based in Atlanta, I am leveraging my extensive enterprise background to adopt cloud-native technologies — containerizing workloads with Docker and OpenShift, and implementing CI/CD pipelines to modernize the delivery of integration services.
