Summary
👤
Senior🎓
Top SchoolDuvan Castillo is a seasoned Software Technical Leader based in Bucaramanga, Colombia, with 12 years of experience designing and delivering web and mobile applications and over 8 years focused on hands-on development. He currently leads engineering efforts at Mercado Libre after progressing from Senior Software Engineer, bringing strong expertise in full-stack architectures, cloud deployments (AWS, Docker), and CI/CD pipelines. Previously he guided technical teams at Conexia where he combined hands-on coding (Java, Node.js, Angular/Ionic, TypeScript) with people management, architecture definition, and technology selection. Duvan pairs a formal background—Magister en Ingeniería del Software and Systems Engineering—with a persistent autodidactic drive to evaluate and adopt emerging technologies. He’s equally comfortable improving developer workflows (Git, Git-Flow, migrations) and implementing QA/testing practices (SonarQube, Cypress, JUnit), which helps him reduce delivery risk while scaling teams. Colleagues describe him as a pragmatic architect who turns complex legacy stacks into maintainable, product-focused platforms.
