Write some Software

Hi, I am looking for someone to develop a system that does the following: 1. Monitors a specific mailbox for calendar invitations. 1.1 The invitation must have in the description the following text (but CAN have more than that - so need to parse): callfrom:+1925xxxxxxx callto:+1924xxxxxxx 1.2 The phone number can be any phone number in international format 2. On every new invitation, it creates a task that will be triggered at the time and date of the invitation. 3. On task trigger it will call the "callfrom" phone number. 4. If answered, it will call the "callto" number and connect the call (like a conference). If not answered - hang up. A few important things - 1. There might be more than 1 "callto" number (for example - conference call) 2. The system MUST work on GoogleAppEngine. If needed, you will need to set it up for us. 3. The system MUST have a small admin (or even use a google sheets) with the following: email | approved phone numbers (comma separated) For exmple: | +1974xxxxxx,+1756xxxxxxx This will be used to make sure that if someone send the invitation, asking to call some number, he is allowed to call that number! (I invite, and it is my number) I prefer the system to use Google Voice (you may see here for an open source project that is very close to this [login to view URL] Or use twilio ([login to view URL]). The person who will work on this will be getting a chance to continue the development of this tool with us.
