Last-Message Delivery App

Avocado Technology
Full-Stack Lead
Team 5

A messaging app that delivers pre-written content (text, video, documents) to chosen recipients when the user stops checking in, reachable even by recipients who never installed the app. Reliability over arbitrary time windows was the whole product.

From-scratch build of a dead-man's-switch messaging app: sends pre-written personal messages (text, video, documents) to chosen recipients when the user stops checking in. Recipients without the app open the delivery on a web view via a one-time token in the notification, SMS, or email. Led the team through the full lifecycle and owned the architecture end-to-end.

Outcomes

  • Recipient web view for people who never installed the app
  • Led the team through the full build lifecycle
  • Multi-channel delivery: push to app users, plus one-time-token SMS/email links to a recipient web view for everyone else
  • Architecture owned end-to-end across mobile, web, backend, and AWS
