Hi everyone!
I’m Nurlan, Tech Lead and Backend Engineer at Monzo.
I’ve written wrote about how we built the Delightful Paymentswhich directly replaced our P2P (Monzo-to-Monzo) and FPS (bank transfers) payment flows.
It explains how we ended up iterating on product in-parallel to getting our designs ready and building stable foundations. And how we benefited from continuous feedback cycles to both polish the product and reduce risks of critical bugs making their way into production.
Hope you find it an interesting read and please let me know if you have any questions or feedback to share
