Spain

Message

At RAKETECH, I worked on the AWS platform behind hundreds of live advertising sites. I cut cloud spend by a fifth, consolidated the AWS estate, and replaced multiple ways of building services with one.

At JOURNEE LABS, I developed the backend that provisioned Unreal servers on demand, using Node.js and AWS CDK. At PATHWIRE, I ran infrastructure across GCP and AWS and worked with developers to address PostgreSQL, Redis, and Kafka processing issues.

As an independent contractor, I worked on infrastructure and backend projects for companies in Spain, the United States, and Europe. I’ve also moved between operations and development, including building automation, backend systems, and cloud platforms.
