Profile: https://flows.cv/chastina

With over 7 years in cloud infrastructure automation and DevOps, I've deeply embedded myself in the tech industry, particularly with public Cloud platforms like Google Cloud and Amazon Web Services. 

My tenure at Twitter allowed me to lead the design and implementation of a critical identity and resource lifecycle management platform on GCP. 

My role as a Sr. AWS Infrastructure Engineer at Bill, coupled with my experiences at Capital One, has equipped me with a unique perspective on infrastructure automation. 

From orchestrating workflows with tools like Terraform and GitLab to being at the forefront of cloud technologies, I've consistently sought to push the boundaries in every role I've held. I take pride in my achievements, and I'm continually inspired by the challenges and innovations that the tech world brings.
