Backend & Integration Developer

Deivid Vanegas

I connect systems that were never designed to talk to each other.

I build backend services and enterprise integrations focused on maintainability, traceability, data transformation and reliable API communication.

01 / About

Built around integration. Grounded in backend.

I'm a software developer with more than three years of experience building and maintaining applications, APIs and data integration processes.

My professional work has focused on MuleSoft, REST APIs, ETL, Oracle, SQL, DataWeave, RAML, JSON and XML. Today I build Java backend services on APX for BBVA at Novatec, and I keep sharpening Spring Boot through production-style projects.

I'm currently in the ninth semester of Systems Engineering, combining academic foundations with hands-on experience solving integration and backend challenges.
