The problem
What slows you down, and what we change
Today
- Weeks of development (accounts, multi-tenant, security) before a first result: every week of delay costs you.
- Trusting your customer data to a technology and a profile you can't verify is a risk that's hard to size.
- A badly designed database costs you in expensive rewrites and slowness as you grow.
With Buildoto
- The structural building blocks are already built and in production: you only pay for their adaptation, at a fixed price, no subscription.
- I design, code and deploy single-handedly, as on beforbuild.com: one point of contact, proof in production, and a 6-month warranty in the package.
- Architecture built to last: tested RLS, clean migrations, controlled operating costs. Your investment doesn't vanish into maintenance.
Freelance Supabase developer, I design and deploy PostgreSQL backends, multi-tenant authentication systems and RAG pipelines on Supabase. Stack already in production on beforbuild.com, delivered at a firm fixed price on a signed scope, from €440 excl. tax.
What I build with Supabase:
- Complete web/SaaS application backend: PostgreSQL database, API, file storage.
- Authentication and multi-tenant RLS: each client isolated, structural GDPR.
- RAG / semantic search with pgvector.
- Firebase → Supabase migration: data, auth and storage, without breaking what exists.
Why Supabase: everything lives in a single PostgreSQL database (data, vectors, access rules), you keep SQL and avoid proprietary lock-in. It's my default when application data is central.
The packaged offer, at a fixed price
No daily rate: a signed scope, a fixed price, a production delivery. The structural building blocks (auth, multi-tenant RLS, pgvector RAG, Stripe payments) are already built and proven on beforbuild.com: you only pay for their adaptation to your business.
- Complete SaaS MVP from €6,600 excl. tax: PostgreSQL database, accounts and auth, multi-tenant, one business feature, deployed. 4 to 6 weeks.
- Feature to integrate from €440 excl. tax: RAG on your documents, PDF generation, signature, automation. 2 to 4 weeks.
- Firebase → Supabase migration: quote after an audit of what exists, dual write for zero downtime.

Who I am
A single point of contact, from audit to handover
I design, develop and run my own features in production: BeForBuild.com, the B2B SaaS I manage single-handedly, is the proof. These proven building blocks, I deploy them in your environment, at a fixed price, and you own them.
You talk directly to the person who delivers: no subcontracting, no agency layer. The one who designs is the one who codes, deploys and hands over.
