Demo profile

DevOps & Infrastructure Engineer

Rosario, Argentina·5+ years·Spanish / English

Bio

I keep services running and deployments smooth. 5 years managing cloud infrastructure, Docker containers, and monitoring systems. I believe in infrastructure as code, automated testing for infrastructure, and postmortems without blame. Studied networking and Linux administration, evolved into modern DevOps practices. I write runbooks, set up proper alerting, and make sure 2am pages are rare. Very async, very thorough with documentation.
