Hi. I am a developer of mobile applications for Android and iOS, but I also develop mobile applications for web, with PHP, JavaScript or Node.js. I have developed before projects that connect Android with Google spreadsheets, through Google Apps Script (GAS) so I know what is the purpose of the work. With GAS I have made data storage from Android to the spreadsheet, sending emails with Gmail, creation of files in Drive, among other functions. I wait for more details per message.
