Start by imagining what problems particular to you that you’d like to solve. Make an information dashboard — command line, desktop, or web. No frameworks. Code it simply and logically. Grab the latest Bitcoin exchange rate from an API. Ask your locally-running node for the latest block height, or balance from your favourite wallet address. Query a nostr relay and do stats on your posting history. Generate alerts based on triggers that you set. Send those alerts to yourself via nostr.

There’s all kinds of data out there to play with. Have fun, hone your skills, and good luck! 😀👍
