The challenge

Money moves in three directions — businesses fund wallets, workers earn per task, and admins approve withdrawals. Every step had to be correct even if a browser closed mid-payment.

What I built

A Next.js App Router app with NextAuth sessions and role-based routing. Prisma models the wallets, ledger, tasks, submissions and payment orders on Neon PostgreSQL. Funding goes through Razorpay: the server creates the order, verifies the signature, and a webhook settles any payment the client missed — safely, because settlement is idempotent.

Result

A production-ready payments flow with an auditable ledger, live on Vercel.

Highlights

• Razorpay checkout with server-side signature checks and an idempotent webhook backup
• Atomic wallet credits with a ledger entry for every money movement
• Submissions, reviews, withdrawals and a treasury view for admins
