UNRIVALED EXPERTISE

Our Talent Has Worked With Top Companies

Having previously worked with these leading global companies, our talent brings valuable insights and expertise to deliver world-class outcomes.

Why organizations choose us

Toptal in Action

Discover the cutting-edge benefits our clients enjoy from the global Toptal network.

Toptal helps Calm achieve better production stability with EKS on AWS.

Challenge: Calm’s existing Kubernetes infrastructure became a source of operational risk as the company scaled. Following a significant outage, the company needed a more reliable platform that could support ongoing growth without compromising stability.

Solution: Toptal was able to immediately help Calm’s team build a new, fully automated cluster to be managed by Amazon Web Services (AWS), running under AWS’s new Elastic Kubernetes Services (EKS).

Outcome: Calm benefited from improved stability, reliable networking, and elimination of costly outages. In the months since, the company has been able to easily absorb significant revenue growth without performance issues.

Toptal’s work was a crucial milestone that enabled us to scale our engineering teams and systems in step with our rapid growth.
