I’m Miles, a senior software engineer at The LEGO Group, in the Brick Experience team on LEGO.com. I’ve been in the retail and e-commerce space for 5 years, with the last 2.5 years spent at The LEGO Group and in that time I’ve learnt a lot about GraphQL and the wider development ecosystem. I’m passionate about improving the performance and developer experience for anyone working on or with our GraphQL API, and have made great strides in improvements with the help of all my talented colleagues here at The LEGO Group. Outside of work, I’m keen to build and display some of the amazing LEGO sets produced today, as well as my Bionicle collection from days gone by. I’m also an avid gamer and Dungeons and Dragons player (and sometimes DM), often combining the two passions!

Show Notes: In the latest episode of GraphQL Radio, we take you behind the curtains at Stellate to discuss how their recent "Cache Like I'm 5" project came together. The wide-ranging discussion is led by Stellate's very own Engineering Manager Andreas Heiberg. Join us on this episode as we dive into the world of cache optimization! It all started during an engineering offsite in Mexico City, where the Stellate team had a breakthrough idea about Maximum Cache Hit Rate (Max CHR) and how it can help users optimize their services. The Stellate team discusses the challenges they faced, the metrics they defined, and the tools they built to provide actionable insights into cache performance. Learn how Max CHR, Uncached Bandwidth, and CHR Impact can revolutionize your caching decisions. Tune in to discover how you can take control of cache optimization with these latest features and improvements.
