Alexandru Vl?du?u is a full-time JavaScript developer based in Bucharest, Romania. He started creating applications with PHP about 5 years ago, but after finding out about server-side JavaScript with Node.js, he has never had to switch technologies again. You may have seen him answering questions on Stack Overflow under the nickname alessioalex, where he is among the top three overall answerers for tags such as Node.js, Express, Mongoose, and Socket.IO. By day, he battles cross-browser compatibility issues, but by night, he brings together embedded databases, servers, and caching layers in single applications using the good parts of JavaScript. Apart from the geeky stuff, he enjoys spending time with his wife.
