I will build your saas mvp with authentication and a billing system


About this gig
If you're a founder validating a product idea, this gig is built specifically for that. I develop SaaS MVPs using Next.js and React, with proper multi-user authentication, a production-grade database, and a structure that's ready for billing when you need it, so you're not rebuilding the foundation once you get your first paying customers.
Deployment goes through GitHub to Vercel with a clean CI/CD setup, and every project includes proper secrets management from day one rather than hardcoded credentials that become a liability later. I also bring a cybersecurity background to these builds, meaning basic vulnerability checks happen before delivery rather than after your first user complains.
This gig is for an actual product you intend to launch and iterate on, not a single internal tool or a marketing site. If what you need is closer to an internal dashboard, check my WebApp gig, and if it's a business website, check my Website gig.
Message me with your product idea and core features before ordering. I'll tell you honestly what fits in a package versus what needs custom scoping.

FAQ
Do you sign NDAs?
Yes, always happy to before discussing product details.
Can you add payments/billing?
The Premium package sets up a billing-ready structure. Full Stripe integration and live payment flows can be added as an extra or custom quote.
Can you help scope my idea if I'm not sure what's realistic for an MVP?
Yes, message me with your idea and I'll help you figure out what's actually needed for a first version versus what can wait.
What happens after the MVP if I want to keep building?
I'm available for ongoing development after delivery, either hourly or as a follow-up project.
