Umar is a leading community authority on the Chrome DevTools. His productivity tips and bleeding-edge insights are consistently A+ and I've definitely learned some tips and tricks from him that I use in my daily workflow.
I've been following Umar's dev tools tips for the past 3 years and whenever I start to think I've got a handle on things, he reveals another hidden gem I had absolutely no idea about. Buy this course right now - you don't know what you are missing out on!
Umar has always been the most prominent figure in our industry when it comes to exposing the powers of the Chrome Devtools, and his collection of tips have been my single reference and “source of truth” when it comes to learning about how I can improve and speed up my workflow using the different devtool features. Since the first day I followed him, I’ve learned more about what I can do with devtools than I ever thought was even possible. He has been sharing literally the most extensive and most useful tips that I’d never seen anywhere before. It’s always been like getting insider access to features as soon as they landed. If you care the slightest bit about improving your everyday dev workflow and getting not only better but also faster and more efficient at what you do, then I highly recommend taking his course. I can’t think of anyone else I’d trust to have the latest and greatest on this topic than him. Don’t miss out on what he has to offer. It'll be 100% worth it.
Umar consistently manages to distill complex and powerful functionality into easy-to-understand examples — be it in video, GIF, or written tutorial form. His unique style of knowledge-spreading makes it possible to learn *a ton* in very little time. Everything he creates has my implicit stamp of approval. 💯
Being an excellent programmer is not only about writing, it's about adjusting, monitoring, and debugging. Developer tools help us understand what is happening in the browser so we can write well-functioning code. I trust Umar Hansa to not only have the most complete information about current devtools, but also devtools that are going to be released in the future. I've saved countless hours debugging and improved my benchmarks thanks to his extremely easy-to-understand explanations. I'm excited about his course because every minute I spend learning from Umar, pays back in dividends while I work.
If you care about better tooling, you want to watch this video series. Trust me on this. Umar is the real deal.
Umar is, without a doubt, one of the foremost experts on browser devtools. I've been at Chrome working on DevTools for years, and yet, the DevTools team, myself included, learn new things about our own product from Umar regularly. :) Don't hesitate on this page, improving your effectiveness with these tools will transform your productivity and enjoyment of building for the web.
