SaaS Starter KitKrzysztof Bednarczuk
I deliver a production-ready SaaS starter kit that includes secure authentication, Stripe subscriptions, and an admin dashboard—so you can launch fast with a clean, scalable foundation. It’s built with real-world reliability in mind (idempotent webhooks, role-based access, migrations, and solid defaults) and comes with clear documentation and deploy-ready setup. My edge is shipping backend systems that are fast, secure, and maintainable—not just demos.
What's included
SaaS Starter Kit
Authentication & Accounts: Email/password signup/login, email verification, password reset, session/JWT, optional Google OAuth.
User & Role Management: Admin-created roles (admin/member), org/workspace support (optional), user invitations, access control.
Billing (Stripe): Subscription plans, checkout + customer portal, trials/coupons (optional), webhook handling, entitlement/plan status syncing.
Admin Dashboard: Manage users, roles, subscriptions, invoices, and basic usage/metrics view.
Core API & Docs: REST API with OpenAPI/Swagger docs, request validation, standardized error handling.
Security & Reliability: Rate limiting, CSRF/CORS (as needed), password hashing, idempotency keys for billing/webhooks, audit logs.
Database & Migrations: Postgres schema, migrations, seed data, and environment-based configuration.
Testing: Key unit/integration tests for auth and billing flows.
Deployment Package: Dockerized setup, CI basics, production-ready env templates, and a deploy guide (AWS/Vercel/Render/Fly.io).
Handoff: Clean repo, setup instructions, and a short walkthrough of architecture + how to extend features.
