Fixing Critical Cloud & DevOps Engineers Bottlenecks
Root Cause: Oversized EC2 instances, forgotten EBS volumes, and unnecessary enterprise NAT gateways draining startup and scaleup budgets.
Root Cause: Manual SSH script deployments without canary testing, rollback strategies, or database migration lock management.
Root Cause: Hardcoded API secrets in repositories, unsegmented VPCs, and non-compliance with strict German/Swiss data protection standards.
