Next.js App Full-Stack Developer

We need a full-stack developer to complete three product gaps in an existing Next.js app built with TypeScript, Tailwind, Prisma/SQLite, and local Hardhat + wagmi/viem. The work includes filling the “Shared With Me” tab by fetching and rendering shared records, adding a date-range filter to the dashboard with validated ISO date parameters, and enabling “Register on Blockchain” from the record detail page for drafts. Deliverables must work in the running app in a browser, not just via API or unit tests.
