Senior🎓
Top SchoolAntonio Espinosa is an industry consultant and senior software engineer based in Barcelona with a decade of hands-on experience building secure, scalable web and back-office systems. He combines deep expertise in IAM, OAuth/OIDC, SAML and JWT with full‑stack proficiency across Node.js, Java, Angular/React, PostgreSQL/MySQL and Elastic stack, often acting as architect and tech lead. His background spans fintech, fraud detection, e-commerce and GIS platforms, where he has designed production-grade architectures, led integrations and delivered L2/L3 support for critical incidents. Antonio also brings a strong security operations pedigree—implementing ISO 27001/GDPR controls, automation scripts and hardened network services early in his career. He is a pragmatic communicator who produces technical documentation, training and product roadmaps to align cross-functional teams. Fluent in turning complex security and integration requirements into maintainable, auditable systems, he now applies that blend of architecture and delivery at MongoDB.
