AWS Cost Optimization · About

AWS Cost Specialist, Not a Generalist

CloudCostDown is run by Adam Pavlát - an AWS engineer who spent 2.5 years optimizing cloud cost and performance at Disney+ Hotstar, one of the world's largest AWS-hosted streaming platforms. Now he applies that same rigour to Series A–C startups paying for infrastructure they don't need.

Why "AWS cost specialist" is different from "cloud consultant"

Most cloud consultants are generalists: they touch AWS, GCP, and Azure, handle migrations, security reviews, and architecture design - with cost optimization somewhere near the bottom of the list.

Adam's focus is narrow by design. AWS cost performance is what he did full-time at Disney+ Hotstar. It's what he does for clients now. Specialists see patterns across environments that generalists miss - because they've seen the same problem fifty times before.

The result: clients get faster time-to-savings and deeper findings than an internal engineer or generalist consultant typically surfaces.

Generalist consultant

  • Multi-cloud (AWS + GCP + Azure)
  • Architecture, security, migration, cost
  • Recommendations in a report
  • Broad but shallow cost knowledge

CloudCostDown (specialist)

  • AWS only
  • Cost performance as primary focus
  • IaC implementation (Terraform or CDK)
  • Pattern recognition from Fortune-500 scale
