Senior Software Engineer (Open Source & Go Language Platform) at Datadog

Terrassa, Catalonia, Spain
Report

I am a Senior Software Engineer at Datadog, where I create and maintain APM Data Collection and Storage Language Platform in Go. With 20+ years of experience in full-stack development, DevOps, cloud computing, and software architecture, I have the skills and knowledge to deliver high-quality, scalable, and secure solutions for complex problems.

I am also passionate about free software, open source, and civil rights, and I actively contribute to various libraries and projects, such as Mergo, a small library to merge Go structs that is used by 60K repositories on GitHub, including Docker and Kubernetes. As a public speaker on topics related to politics and technology, I aim to empower people and organizations to build and use software that is ethical, reliable, and respectful of human dignity.
