@raulcoza
I build scalable Java platforms and cloud architectures for healthcare, banking, ecommerce, and global communications.
What I'm looking for
I've built distributed Java platforms used at national and global scale, including IBM's German electronic patient record platform serving over 60 million people.
At HTEC, I led cloud architecture and event-driven fulfillment systems for Ocado Smart Platform, supporting retail networks including Kroger, Aeon, and Auchan. I've also shaped transfer systems for Santander, payment services for Klarna, and financial-data ingestion for the London Stock Exchange.
I lead teams through architecture, API design, cloud deployment, delivery, and mentoring. My hands-on stack includes Java, Spring Boot, Kafka, Kubernetes, and multi-cloud platforms across AWS, IBM Cloud, GCP, and Azure.
