    // The problem

    Whale Together needed automated limit-orders for NFTs — secure wallet handling, real-time event processing, and flexible trait filtering.

    // The process
    1. 01

      Built a CRUD API for limit-order resources with encrypted wallet data.

    2. 02

      Integrated an event processor to execute orders as tokens were listed on OpenSea.

    3. 03

      Added customisable trait filtering, gas presets, and expiry management.

    // The result

    A working automated-trading system that monitored listings and executed limit-orders in real time.

    // Takeaway

    Early proof of the automation and event-driven engineering we now apply to business workflows — the same patterns, pointed at operations instead of NFTs.
