We have a web app and mobile app on React and React Native. You have to make a form for both web and mobile and add a share button in a list, add country code with mobile number input field, and remove a required option. If you can finish this within 4-6 hours then bid other wise don't waste my time please. Also you have to start right now and I will show you the changes. *******Don't bid if you can't able to start right now. Also please start your bidding message with "I can start right now".
