System / Devops / Linux engineer and administrator

Martin Konicek

Who am I

I am a self-learner who was always interested in electronics and computers. Currently I switch my focus from Site Reliability Engineer to more of DevOps role which is AWS related. I am helping my company to develop Serverless aplications in Python and create complex cloudformation templates and whole environment. I am very proficient in infrastructure development. I use GIT, CI/CD pipelines and other developer support tools often. Currently I am learning to be AWS Cloud Architect Asociate – I have already finished practitioner exam.
