Dmitry Shashkov

Site Reliability Engineer

From the start in IT as QA Automation Engineer I was mainly focused on automating routine stuff and dealing with the infrastructure, so it was natural for me to transition into DevOps field after some time. Now I help to create CI-CD processes for cloud-native applications that make development experience easier, cut cost and ensure availability.
