Summary
🤩
Rockstar🎓
Top SchoolAndrew Garrett is a senior software and platform engineer with 13 years building resilient, self-service cloud platforms—most recently owning core parts of Braintree’s AWS/Kubernetes-based deploy ecosystem. A prolific reviewer and Kubernetes contributor, he blends deep systems knowledge (Linux, container CPU throttling, Calico CNI) with hands-on automation in Python, Go, Terraform, Ansible and bash. He has production experience doing Kubernetes The Hard Way on-prem and in AWS, and has contributed robustness fixes to widely used open-source projects like aws-cli and moto. At PayPal he designed and maintained a Cassandra-backed key-value REST service and led its Docker/OpenStack lifecycle, showing a pattern of shipping and operating critical infra. Quirky extras: he maintains dual-level docs for users and engineers, runs a home recording studio so he sounds great on calls, and still insists on correcting Python default-argument misconceptions.
