Nemanja took our Webflow site from failing performance to genuinely fast. Mobile Total Blocking Time dropped from around 30 seconds to under 50 milliseconds, and desktop cleared Core Web Vitals. What stood out just as much as the numbers is his honesty: he tells you what actually moves the needle versus what's just chasing a lab score, and flags trade-offs upfront instead of overselling. Deeply knowledgeable on performance and easy to work with over the long haul.
Nemanja is a fantastic developer. He does what he says, he moves fast, gets the big picture, and — he's an absolute pleasure to work with.
