COVID Slack Bot
A Slack bot I built early in the pandemic to pull COVID-19 numbers straight into a workspace. Typing /covid-state-data CA or /covid-usa-data returned not just cumulative positives, negatives, and deaths but daily changes and 7-day moving averages, all formatted as Slack Block Kit messages. It read live figures from The COVID Tracking Project's API, verified every request with an HMAC signature, supported an OAuth install flow, and shipped as a Dockerized Rails service tested in CI. It wound down in 2021 when The COVID Tracking Project stopped collecting data.
