Hi,
After reading over your job application It looks like a perfect fit for my skill sets. I am a nodejs, angularjs, vue.js, android and ios expert. We have built more than 7 chat app.
As a next step, I request you to please initiate by replying so that we can discuss on the requirements and finalize the project scope with the exact feature list and then will be able to suggest you a final cost/timeline.
Looking forward to your reply.
