I keep cloud platforms fast, reliable and cheap to run.

15 years shipping software, the last five running AWS & Kubernetes in production. I also build CostGuard, which switches off idle AWS environments so you stop paying for them.

Projects

CostGuard — Stop paying for idle dev & staging on AWS

CostGuard shuts down tagged dev, staging and test resources outside working hours and brings them back on schedule. It covers EC2, RDS and Auto Scaling, leaves untagged (production) resources alone, logs every action, and lets anyone spin a stopped resource back up with a temporary override.
