Top SchoolRafael López is a backend developer with 13 years of experience building scalable, maintainable systems in Java and Python, currently contributing at DEKRA Digital & Product Solutions. He has strong microservices and API-first expertise—designing BFFs, event-driven integrations with Kafka, gRPC and REST, and production observability—alongside hands-on persistence work with MongoDB and thorough testing practices. Rafael also experiments beyond backend boundaries, developing multi-agent LLM systems in Python and mobile apps with Flutter, and has contributed to the computer-vision open-source library DBoW3 by integrating it with OpenCV. Based in Córdoba, he combines industry work with community leadership as GDG Córdoba coordinator and long-term organizer of developer events, bringing a research-minded curiosity from his ties to the University of Córdoba. Notably, he values iterative learning through personal projects where he intentionally “fails and tries again,” which drives both his technical depth and collaborative approach.
