The problem The Afterparty solves

The Problem

Event organizers spend months building experiences, sponsors invest thousands to reach their audience, and attendees travel far for valuable connections – but the moment the event ends, organizers lose their community, sponsors lose touch with prospects, and attendees can't continue the conversations that just sparked, wasting everyone's investment in a single moment.

Challenges I ran into

One of the key technical challenges I encountered was implementing image messaging within the XMTP protocol, which is text-based. I solved this by converting images to base64 encoding, allowing them to be transmitted and stored as text strings while maintaining image quality and compatibility across the decentralized messaging system.
