Performance engineering

Optimising performance for speed and scale. 

Here you can edit the background of the section

We believe that everyone should experience good performance, whether you're on a low powered device or live in an area with slower internet speeds.

Performance Engineering is a culmination of skills and techniques we can bring to ensure that any applications you deliver can scale to meet the demands of your customers, but also deliver the user experience they expect.

By getting involved early we can help to design solutions that are built for speed and scale. We align to continuous development principles through Agile and DevOps to ensure any issues are addressed as early as possible. We know some issues are only ever found ‘in live’, so with targeted monitoring and a continual feedback loop, we can ensure your platform is always running optimally.

Our Services

We offer 3 key services as part of our Performance Engineering framework

Performance Assurance

At every step of their development pipeline we’ll measure the performance of your application changes so they can be shipped to your customers.

Page Speed Optimisation

We’ll work with you to identify what content you want your customers to see first, and how to deliver that efficiently. We’ll also ensure you can assess the impact of your changes, good or bad and identify the impact third parties are having on your page speed.

Application Optimisation

We’ll help you design your systems with performance up front. We'll also profile your code to identify the slow bits and tune your infrastructure and config so it's fully aligned with the workloads your application needs to meet. We’ll always measure what's happening ‘in live’, and feedback recommendations to your delivery teams.
