Top SchoolYun Guo is a Senior Software Engineer with a decade of hands-on experience designing and operating large-scale database and cloud-native systems across MSSQL, Postgres, MySQL, MongoDB and modern AWS infrastructures. Currently at Datadog after a multi-year tenure at Cvent and a stint at GitLab, Yun blends deep database tuning, automation (PowerShell, Bash, Python), and DevOps practices—having built tooling for automated T-SQL generation, Chef cookbooks, CD pipelines, and ECS migrations.

Comfortable across stacks from .NET and Ruby to Node and Python, Yun is equally at home optimizing queries as building service provisioning and deployment automation that reduce toil at scale. An avid AI enthusiast who favors Python on GitHub, he brings research-minded problem solving to production reliability and performance challenges.
