At Split → Harness, I build and operate Node.js and GraphQL services for feature management and experimentation. I developed identity and access capabilities including JWT propagation, service-to-service authentication, SAML, SCIM, and scoped API keys.
I also improved the GraphQL BFF’s reliability, added observability and on-call alerts, and owned a feature-flagged rollout across production clusters. With Product and Design, I delivered Large Segments, Vercel integrations, and a data-migration CLI.
I led the team rebuilding the product as a micro-frontend, defined its architecture, and wrote reusable AI agent skills to support consistent migrations. Earlier, I built Kafka pipelines at Tecnotree Corporation that processed around 300 million messages a day, and internal payment tools at Mercado Libre.
