Over deze dienst

Are you a founder ready to launch your SaaS but stuck on the complex plumbing of payments and user authentication? Don't let bad security or broken webhooks ruin your launch.


As a Level 1 Seller and Software Engineer with over 7 years of industry experience, I build secure, robust, and production-ready payment systems that scale. I will handle the backend heavy lifting so you can focus entirely on your product and your marketing.


What I can build for you:

  • Secure Authentication: JWT, Firebase, Auth0, or NextAuth (Login, Signup, Social Auth).
  • Stripe Subscriptions: Monthly/yearly multi-tier pricing setups.
  • Stripe Webhooks: Flawless handling of successful payments, failed invoices, and cancellations.
  • Customer Billing Portal: Allow users to securely manage, upgrade, or cancel their plans.
  • Clean Code Architecture: Easy-to-maintain code delivered straight to your repository.


Lets stop wasting time troubleshooting API docs. Send me a message with your tech stack, and lets launch your SaaS billing securely this week!
