About Me

Senior Fullstack Developer with 20+ years of experience in software development, leading frontend and backend initiatives with a strong focus on architecture. At Santander/PagoNxt, led a 10-member frontend squad and built a unified Design System with Storybook and CSS modules, driving consistent UI development across multiple global projects. At South System, architected a real-time remote device monitoring platform using C#, Node.js, and AWS serverless services. Most recently at Fanatics (via Avenue Code), implemented new API features with Go, Temporal, and Kafka, and refactored legacy Go and React codebases, boosting backend performance and reliability across event-driven systems.
