From blank repo to a live, billed SaaS

I take your subscription product from an empty repo to paying customers — auth, billing, and multi-tenancy done right the first time.

You have a SaaS idea and need someone who can ship the whole thing — not just a pretty front end. I build the full product in Go, React, Stripe, Postgres and Auth: sign-up, org isolation, subscriptions with feature gating, and the admin tools you'll actually run the business on. I've shipped this exact category before, including a fintech SaaS and my own product, so the hard parts aren't a guess.

What you get

  • A live product real users can sign up for, log into, and pay you through
  • Stripe subscriptions with feature gating, proration, and dunning when cards fail
  • Multi-tenant architecture with clean org isolation and role-based access
  • Secure auth: sign-up, login, password reset, and team invites
  • Postgres schema and Go APIs built to scale without rewrites
  • An admin panel to manage tenants, plans, and billing — plus a deploy you fully own

Proof

  • FinHOABuilt a fintech SaaS for homeowner associations — dues collection, accounting, and multi-tenant resident portals with each HOA's financial data cleanly isolated.
  • NixblyFounded and built my own SaaS live on React, Go and AI — so I've shipped the billing, auth, and multi-tenancy on a product I own, not just for clients.

FAQ

What does a SaaS build cost?
A standard B2B SaaS with Stripe subscriptions, roles, and an admin panel runs $30K–$60K; once you add full multi-tenancy and team-level billing it's $55K–$85K. That's US-market value for the work — building it nearshore from Mexico is where you save versus a US agency. I give you a fixed quote after discovery, so the number doesn't move on you.
How long until I can charge customers?
A standard billed, multi-tenant MVP is 3–5 months from kickoff to live and collecting payments. A simpler single-tier product can be 4–8 weeks. The biggest lever on timeline is a tight discovery phase deciding exactly what's in v1.
How do we work together?
We start with a discovery call and a written plan — scope, timeline, fixed quote. Then a clickable prototype of the core screens before code starts, weekly previews of tested real code, and a final deploy with handover and a support window. You always know what's shipping next.
Why work with you instead of an agency?
You get one senior engineer who's shipped this category end to end — billing, multi-tenancy, and all — not a junior team handing work up a chain. I'm in Puebla, Mexico, working in your timezone, at a fraction of US-agency pricing.
