LitStream Pro.
LitStream Pro lets anyone open a branded ebook store on its own subdomain or custom domain and resell a curated catalog while keeping 100% of each sale. We built the platform end to end, from Stripe Connect payouts and a protected reader to five role consoles, and later reworked it into a books-first curated store.

The challenge
Independent sellers who want to sell ebooks direct need a storefront, payments, a way to deliver books without leaving files wide open, and someone to help them launch. Stitching that together from separate tools is slow, and most platforms take a cut of every sale. The client wanted a turnkey store business with no commission on book sales.
What we did
- Built a pnpm monorepo: a Next.js front end with subdomain-based multi-tenancy, and an Express, Prisma and PostgreSQL API with Redis and BullMQ for queued jobs.
- Wired Stripe Connect so customer payments land directly in each seller's account, and added custom domains through Cloudflare for SaaS.
- Developed a protected in-browser reader with per-buyer email watermarking, copy and print blocking, audio narration, interactive widgets, and an installable PWA.
- Shipped five role-based consoles (super admin, staff admin, onboarding specialist, seller and book buyer), an AI support chat that hands off to a human, and refund and chargeback evidence tracking.
- Ran every change through a pull request with CI type checks, tests, a production build and gitleaks secret scanning, then restructured the main domain into a books-first curated store.
