About

I’m currently a Senior DevOps Engineer at Sii , where I design, maintain and troubleshoot AWS-based cloud infrastructure. I also support the development teams in creating CI/CD pipelines and improving processes to ship products quickly and safely.

Technical expertise

I’ve been doing system administration for over 10 years now, starting at helpdesk in a web hosting company, then supporting a software house as a one-man (sysadmin) army, subsequently growing to be a seasoned cloud administration expert. I tend to work closely with the development teams, embracing the DevOps methodology and enabling product teams build quickly, while keeping the underlying infrastructure operating safely and stable.
