• As configuration tree owner, I'm responsible for building a site entirely from scratch periodically for finding and fixing any configuration issues. I also work on analyzing and resolving functionality issues reported by regression team.
• Helped client teams to adopt this new configuration management process.
• As backup for the team lead, I manage day to day activities of the team as needed.
