What we built

A 600-account AWS organisation with no tagging discipline and runaway data-pipeline spend. We delivered a FinOps audit, rightsizing program, and ongoing anomaly detection.

Costtrail engaged on a fixed-scope SOW basis across 2 pillars — Cloud Engineering, DevOps & SRE. Delivered in 2-week sprints with weekly demos, eval-gated deploys, and quality checks at every milestone. Code, infrastructure, and operations were handed back to the client team at close, with optional 24/7 SRE support after launch.
