From there, they turn to performance at Tinder today: crash rates are strong (99.5 to 99.7% crash-free), but app hangs and ANRs are the bigger challenge. Aaron breaks down how his team attributes regressions to the right team and experiment.\nAaron also shares how he's built leadership trust on long-term infrastructure bets, and what he learned managing up during a CI consolidation debate with the backend team. He passes along a rule of thumb for using AI without losing the learning: write something once with AI to move fast, once yourself to actually understand it, and a third time to get the architecture right.","thumbnail_url":"https://img.transistorcdn.com/YI0Unx6Qb9KLViuYiPEmdR6Iz3pDcmFiJ4_Mhk4teL0/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9kNzIw/MTRiOTUwM2NmNGNl/NzkyYzM4NzM3OTFm/NjUyMi5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
