Excited for this! Could you please unify the non-facilitator entries into one and pick a category that best describes what you do? In future we might allow using multiple tags for one submission and I understand you provide more than one solution but for now please limit the submission two: 1. your facilitator entry. 2. one of the three entries (Infrastructure & Tooling, Services/Endpoints, Client-Side Integrations)

Thanks!
