Hello,
Interested in the job.
I am a Software Engineer specializing in end-to-end Web Development.
I have expertise with Google's Cloud Platform and I am quite adept with Google Apps Script (GAS) and its GSuite APIs (Sheets, Docs, Calendar, Form, Slides, Gmail etc.). Slack's APIs requires OAuth 2 authentication and I know how to effectively leverage Google Apps Script to authenticate against 3rd party APIs using OAuth2 authentication flows. I have years of experience working with Google Sheets at the script level and updating a sheet based on results from an API query is a common task for me. Google Apps script also support cron-like operations meaning its possible to automate data capture and have a sheet update itself periodically, a feature your application may benefit from if implemented correctly.
I believe I've covered the primary requirements of your project and offered some insight into how it may be further improved should you desire to explore those options.
Thank you for taking the time to review my application and I look forward to discussing your project in greater detail.
Regards,
Damion Murray
