Senior Java Engineer at Globant who designed Banamex’s GraphQL architecture and increased sprint delivery by 30% with AI-assisted development.

Colombia
Message

At Globant, I designed the end-to-end GraphQL architecture for Banamex balance and transaction use cases, using Java 21, Spring Boot, and WebFlux. I defined SDL standards and DataLoader patterns, and integrated Apache Pinot through REST clients.

I used GitHub Copilot and Globant’s NEO AI to support code generation and observability, increasing story points delivered per sprint by 30%. I also produced organization-wide Copilot best-practice reports and code-review examples.

Before Globant, I defined Java EE development standards as Software Architect at Datatools S.A. At Jaime Torres C. y Cía S.A., I optimized a bank log-reconciliation process from two hours to 15 minutes; today, I’m developing a personal finance and reminder platform with a Java/Spring Boot backend and a React front end.
