If you are interested, we would love the opportunity to talk to you about Hacktoberfest and our API libraries.

Our agenda would be: Explore what you liked and is there anything we can do to improve?

You can grab a time on my calendar that works for you and we can have a chat on Google Hangout or Skype. If you prefer, you can email me using my GitHub username at my company’s domain.

Thank you so much,
