Hi i have read your job description and after reading that i am thinking that i can make your app As a PWA as you want it to be done but now currently your website is not live but once its running and i will make it PWA and if you want me to make it live then i can do that too for you .
I have 5 years of working experience in angular and i can develop and deploy a lot of angular and other web applications so i can do your app work too .
I am looking forward to work with you thanks .
Best wishes Abdul Mateen.
