Summary
👤
Senior🎓
Top SchoolCesar D is a Senior Software Engineer based in Madrid with over a decade of professional experience and a 20+ year history of building backend systems across Java, PHP/LAMP and modern stacks like MERN, Kotlin and Spring. He has repeatedly led architecture, design and team coaching efforts—teaching Git and Docker and championing test-driven development—at companies from Telefónica to ASSIA and currently at Expenti. Comfortable working across microservices, REST APIs, container orchestration (Docker/Kubernetes) and both relational and NoSQL datastores, he blends deep backend craftsmanship with front-end and DevOps fluency. Notable for moving between legacy enterprise stacks and greenfield cloud-native projects, he often serves as the bridge that modernizes monoliths into resilient services. A Master in Software Engineering from Universidad Politécnica de Madrid, he pairs pragmatic engineering with mentoring instincts and a curiosity for cross-platform solutions that span mobile, web and infrastructure.
