At Kairos DS, I run and evolve Amanda, the distributed platform serving 100% of Inditex's global media delivery. I ship changes with unit, integration, and end-to-end tests, and built a distributed tracing layer using W3C Trace Context.

At Paradigma Digital, I designed and built Amanda from scratch as event-driven microservices using Pub/Sub and Kafka. I also built Node.js microservices for Prisa's audio streaming platform and cut BigQuery hits by over 90% with a Redis caching layer.

At Mediktiv, I built a multi-tenant health SaaS from zero, including about 15 NestJS microservices. I also built a travel aggregator for 200 agencies at Gestyde, and solo-built Kuibi, an AI voice interview coach.
