The platform was being held back by performance
The platform wasn't broken, but it could have been better. There was a lot of traffic, new features were added all the time, and people were still highly interested. But behind the scenes, problems with performance were slowly making the user experience and scalability worse.
When there were a lot of people on the site, it took a long time for pages to load. There were times when new features made things worse. Developers spent more time fixing issues than making the product better. These problems weren't too severe, but they did slow things down.
This case study shows how we made a high-performance online platform by changing the way it was planned, improving the way it was delivered, and making performance a part of every stage of the process.
