Hello,
Deep is here from Ahmedabad.
I have experience with Arduino - WiFi Web page hosting, Server HTTP request handling, Button/Switch Detection, Web page configuration for required parameters and Serial communication.
I can help you to develop Arduino code that can send request to HTTP server on a particular button press and take action according to the response received from server. As well as Arduino will host a web page that can take configure server URL / API and Serial communication parameters like baud rate, Parity, Stop bit, etc.
