SaaS Platforms & Web Apps
Multi-tenant web platforms with auth, billing, and dashboards.
Full-stack SaaS builds — auth, roles, billing, admin, dashboards — on TanStack Start/Next.js with Supabase or Postgres. MVP to production.
Problems I solve
- MVP stuck between prototype and production
- No auth, roles, or billing wired up
- Data model won't scale past first 100 users
- Admin & internal tools built in spreadsheets
What you get
- Multi-tenant architecture with proper RLS
- Auth, roles, invitations, and org switching
- Stripe billing (subscriptions, usage, seats)
- Admin dashboards + customer-facing product UI
Use cases
MVP → production hardening
Take a prototype and add auth, RLS, billing, and observability without a rewrite.
Multi-tenant SaaS from scratch
Org model, invitations, roles, and per-tenant data isolation on day one.
Internal ops platform
Replace spreadsheets and Retool with a purpose-built admin your team owns.
Customer-facing dashboards
Charts, tables, filters, exports — fast, accessible, and mobile-friendly.
Examples I've shipped

Outcome — MVP → paying customers in 8 weeks with orgs, roles, and metered billing.
Healthcare ops platform
Outcome — HIPAA-aware multi-tenant admin replacing 5 spreadsheets.
Marketplace back-office
Outcome — Vendor onboarding, KYC, and payouts in a single admin.

Frequently asked questions
Can you extend our existing codebase?+
Yes — I ship PRs into your repo and follow your review process. I can also run standalone if you're pre-team.
Do you use Supabase or roll our own?+
Both. Supabase for speed and standard shapes; hand-rolled Postgres + Auth.js when you need custom infra or on-prem.
Who owns the code?+
You do — 100%. No proprietary framework, no vendor lock. It's your repo and your infra.
