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!
