A developer shared their experience building a chatbot named Pickup that utilizes Walrus mainnet for cross-device user memory. The primary engineering challenges involved ensuring smooth integration of decentralized storage with a real-time chatbot, rather than the storage itself. Key lessons learned include implementing timeouts for memory retrieval to avoid chatbot freezes, optimizing write operations by replying first and saving in the background, filtering unnecessary memories, designing around consistency issues where writes aren't immediately readable, queuing writes to prevent rate limits, and providing user visibility into what the chatbot remembers.
