Worked on the panther-labs/panther-analysis repository to deliver an environment upgrade focused on maintaining runtime and telemetry consistency. Upgraded the Python version in the Dockerfile from 3.11.9 to 3.11.11, ensuring compatibility with downstream dependencies and reducing security risk. Updated CloudTrail user-agent strings to reflect the new Python version, supporting accurate telemetry and smoother deployments. Leveraged skills in CI/CD, DevOps, and environment management, using Dockerfile and YAML to implement and document the changes. This work reduced environment drift, improved stability, and ensured auditability through formal commit and changelog entries, contributing to ongoing maintenance and operational reliability.
