I work remotely as a freelance Frontend Engineer, while traveling through the world. If you are looking for an Angular expert, you have found it! I'm in love with Angular: I started using the version 1.x many years ago and switched to Angular 2 as soon as it was RC. I like to mentor other developers, helping them with coding issues, solving bugs and improving their code. I also recently started a blog with some Angular tips: http://blog.danieleghidoli.it/

I began building websites in the 90s, did freelancing in the 00s, and have been working as a salaried software engineer at small and large companies in and around NYC since the 2010s. Most of my experience is on the front-end but I've done a little of everything – frontend, backend, app development, infrastructure, cloud...
