Skills
I am an experienced engineer with over ten years in the DevOps, platform and software Engineering fields.
I specialise in infrastructure as code, cloud and container technologies and everything that revolves around them.
The projects I work on are usually a composition between infrastructure and software development. Examples include public cloud, platform or software as a service solutions.
Additionally, because I have a background in hands-on systems engineering and networking, I understand how cloud-native technologies relate to the hardware they actually run on.
I am as proficient in automating infrastructure as I am in creating services, platforms or automation tools themselves.
