Created a new SPA PWA frontend app for a big Java web application from scratch all by myself (lots of prototyping for the marketing department), then hired a couple of other FE developers to the team. Revenues skyrocketed after this was released. We hosted campaigns with huge traffic 'First commercial flight to space', and 'Hamilton'. I set up a very effective CDN and caching policy, and we hold up 100k+ concurrent users.
