Sebastian Andrei Roman
DevOps|SRE Engineer
Bucharest
Summary
I like to define myself as an engineer, with DevOps mindset, with experience on every layer of an application deployment, starting from architecting infrastructure to fully deployment pipeline.My experience was developed on deploying and administrating microservices apps on public or private clouds, developing fully automated pipelines for different projects on different industries, starting from telecom to public sector. On all my steps I'm trying to have eyes on monitoring, logging and security part also, to avoid incidents that can impact clients and end users. My goal is to improve myself by improving the environment where I'm 'deployed'.
