Performance Engineering

Tackle performance challenges head-on and protect your users, revenue and reputation.


Our Performance Engineering services support the software development lifecycle with our unique methodology that enables us to identify and resolve risks early. Performance Engineering is carried out during design, build, testing and deployment of new systems and applications.

Performance Engineering is

  • Proactive, continuous, and end-to-end application performance testing and monitoring.
  • Allowing seamless collaboration between teams, tools, and processes through continuous feedback loops.

We combine our unique methodology with our powerful proprietary software to help you identify performance risks early through test automation – including performance testing, stress testing and load testing.


Results we have delivered to our clients

  • £12M increase in the Black Friday revenue of an e-commerce platform by eliminating critical system bottlenecks.
  • Scaled core Test & Trace systems to achieve 6M Covid-19 tests per day
  • 96% reduction in service-impacting incidents 
  • Over £1M p.a. efficiency saving through automated quality engineering 
  • £700K reduction in test tool costs by migrating to an open-source alternative

Our Approach

Free Diagnostic – Identify performance optimisation opportunities to improve user experience and system scalability. Similar to the Cloud Cost Optimisation this diagnostic is data-driven using your performance production data. We will identify opportunities to improve any of the 7 pillars of performance.

Discovery – First paid engagement. Setting the optimisation targets and putting an implementation plan in place to realise those performance optimisations. At this stage we also identify the risks across your people, processes, and technologies.

Realise – Working with your teams to deliver the implementation plan.

Transform – At this stage we help you build an enduring performance engineering capability within your teams in order to deliver an on-going engineering practice.

Support – Maintain capabilities in your teams ensuring they function smoothly no matter what is thrown at them.
