Next.js + Supabase developer for creator link-in-bio startup

A year ago I started building a link-in-bio tool for creators, the kind where a musician or a coach gets one page that holds their links, a small shop, and a way for fans to send a tip. We've launched, a few hundred creators use it, and the money side is starting to matter. We're a team of four, two of us technical, and we're now looking for a developer to join long-term. The product is a Next.js app (App Router, TypeScript) on Vercel with Supabase behind it for database, auth and file storage. Payments run through Stripe Connect, so creators get paid straight to their own accounts. Most of the code is reasonably tidy, though some parts were written in a hurry and could use some love. Your days would be a mix of new features and fixing what users report. Right now on the list: a better analytics view for creators (clicks, tips, top links), custom domains for pages, email receipts after a tip, and some row level security cleanup in Supabase that has been sitting on the backlog for too long. Nothing exotic, but it needs someone who likes working directly with the product, not just tickets. We use GitHub with pull requests and review each other's code, tasks live in Linear, and we do a short standup three times a week on video. Everyone talks to everyone, there's no heavy process. You'd talk with me, the founder, about what to build and why, and with our other developer about how. We're happy to take someone earlier in their career if they're curious and write careful code. Tell us what you've built, even if it was a side project, and which part of it you're most proud of.
