What I'm looking for

I'm looking for a fully remote role where I can build scalable cloud applications, modernize systems, automate infrastructure and CI/CD, and collaborate with distributed international teams.

I've delivered cloud migrations, middleware, and production applications for Sofka Technologies, GFT Technologies, Bancolombia, and government-facing platforms. Most recently, I migrated API Connect flows into Spring-based applications, built real-time IBM Data Bus middleware, and automated AWS deployments with CloudFormation.

At GFT, I migrated 100% of AWS accounts to infrastructure as code, containerized microservices with Docker and Kubernetes, and delivered Bancolombia's mobile package recharge service through production. I also build secure Java and Angular applications using Spring Boot, REST APIs, OAuth 2, Keycloak, and relational databases.

I'm an AWS-certified backend and cloud developer who works effectively with distributed teams across LatAm, Europe, and India. I bring hands-on experience in CI/CD, Azure DevOps, testing, modernization, and AI-assisted development, and I'm open to fully remote roles.
