Redesigned the FDIC's online deposit insurance calculator to be 100% client side just before WAMU fell over and the crash that followed. Before the three-step one pager it was a UX that only a mother could love on payday. The bigger problem was every time it would end up on somewhere like Yahoo finance (don't laugh, this was 2007 and earlier) it would fall over like this database. The key to scaling it seems pretty obvious today, write all the searchable data out to a single JSON file and have the browser poll that. It was doing multiple millions of user sessions a day I was told and couldn't have been deployed at a better time. Some projects you get lucky with I suppose. I check it out every once in a while and the UX is basically still the same. |
