We first create detail document of client requirement. We sure make sure that client and our team will be on same page.
Then we design whole project on PSD/Figma and get it approved from our clients.
After confirming about design, our development team works on web/mobile app.
We test each and every module and make sures that web/mobile app is bug free. We also do code review for product quality.
Finally we debug and deploy on our server.
