You will get a production-ready SaaS backend with Node.js and PostgreSQL
Project details
You will get a scalable SaaS backend built for production, not
just for demos.
I build multi-tenant backend systems with Node.js, TypeScript,
and PostgreSQL. I have shipped 3 production SaaS products used
daily by real users, including a complete billing platform with
locked workflows, PDF generation, and audit logs, and an
inventory system with real-time stock logic and monitoring.
You get clean DDD architecture, JWT authentication, Swagger
documentation, and a deployed, production-ready backend.
Stack: Node.js, TypeScript, Express, Prisma, PostgreSQL,
Next.js, Docker, Sentry.
