RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Built a realtime collaborative interface with presence, optimistic synchronization and resilient reconnect behavior.
Use this as a starting structure, then replace it with your real implementation details, metrics and constraints. Do not claim outcomes you did not measure.
STRETCH GOALS
Go deeper if the core is already solid.
CRDTs
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Offline mode
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Presence cursors
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
