He has deep experience designing RESTful services, NoSQL/relational data models, large‑scale batch processing and search indexing (Solr/Lucene), and a strong test‑driven approach using JUnit, RSpec and BDD tools. Past roles include architecting Abril’s digital commerce platform and delivering mission‑critical internet banking systems for major banks, demonstrating both product and enterprise-grade reliability.
