From crafting beats as a musician and producer to building workflows in Airtable and no-code tools, my journey has been one of constant learning. Now I'm exploring fullstack development with Convex, curious to see how far I can push myself and picking up something new every day. This booking component is my first contribution to the open-source community — still a work in progress, so if you spot bugs or have ideas, I'd genuinely love to hear from you.
