Hi,
I have checked your post in which you required front-end developer for your progressive web app and I have extensive experience with front end development
which include the following skill: -- Front-end (HTML5, CSS3, Bootstrap, JavaScript, Angular.js, vue, Ajax)
To get start kindly share the existing web app link and list of adjustment and tweak that need to be done.
I have desired skills and expertise to carry on this project and have accomplished many such Challenger projects with custom work and complex features. Hence there would not be an issue for me.
Looking forward for your response
