Squiggle

Slack-integrated photo annotator. Quick markup, no context switch.

Problem

• Circling one thing in a screenshot meant leaving Slack, opening an editor, saving, and uploading again.

Approach

• A Slack app: upload, annotate, share, all in the flow.
• The work is mostly in the integration: interactive components, message updates, file permissions, OAuth scopes.

Outcome

• Shipping a real integration is a humbling exercise in reading other people's docs carefully.
