Why new Date() parsing is a trap, why UTC in the database and local on the screen is the only rule that scales, and the classic bugs – a report short by a day, a deadline that arrives early.

One 3000px JPEG for every visitor is the most common performance bug on Indian sites. How srcset and sizes actually work, when to use picture, and what WebP and AVIF are really worth.

GitFlow was built for shipping versioned desktop software, not for four people deploying every week. A simpler branching model, and the written rules that settle merge versus rebase for good.

Measure first, then fix in the order that actually moves the number: images, render-blocking code, fonts, caching, plugins. With real before and after figures from a six-hour rescue.
