Hi, I am Tiago Carreira

I am a Devops Engineer
I am a Developer
I am an Artist
I love Open-Source

Tiago Carreira (tcarreira)

Senior DevOps Engineer at Montblu

Having 10+ years of experience with DevOps, I’m experienced with modern technologies (eg: Docker), proficient with Linux systems and many DevOps tools (Kubernetes, CI/CD, IaC) and I’m a Python and Go developer.

Passionate about Linux, Open Source and productivity (I love scripting and automation). No person should be a single point of failure - procedures should be documented and/or automated.

I’m looking towards working with smart people, with whom I could learn and help learning; where autonomy is a valuable asset and improving is more important than finding who made a mistake.

Also president of the board of ANSOL - Portuguese Association for Open Source Software (ansol.org).
