Custom back-end

APIs, databases and integrations built to last.

Back-end development billed hourly (110 CHF/h) or as a fixed package. Ideal for completing an existing project, integrating a third-party system, or building an API from scratch with Supabase, PostgreSQL and Node.js.

What you gain

Why this choice.

✦

Modern, maintained stack.

Supabase (PostgreSQL + Auth + RLS), Next.js API routes, Node.js. Technologies in production at thousands of teams — not exotic choices that become orphaned.

◎

Security by design.

Row Level Security (RLS) to isolate data by user. JWT authentication. Environment variables, never secrets in code. No security compromises.

⟳

Systematic documentation.

Every delivered API is documented (TypeScript types, README, comments). The next person to take over the code understands what was built and why.

Who it's for

This service is right for you if…

You have an existing front-end and need a back-end API.

You're using a costly SaaS tool you want to replace with your own solution.

You need to integrate a third-party system (ERP, CRM, payment, logistics).

Your database is growing and you need an architecture that can handle the load.

FAQ

What we're
often asked.

Direct answers to real questions.

Why Supabase rather than a custom back-end?

Supabase provides managed PostgreSQL, Auth, Storage and Edge Functions: everything most SMEs need, without managing infrastructure. For very specific needs, a custom Node.js back-end may be preferable. We choose based on the use case, not habit.

How does hourly work?

You describe the need, I give an hours estimate. If you approve, I start. A detailed hours report is provided at invoicing. No hours billed without prior agreement.

Can any third-party system be integrated?

Any third-party system with an API (REST or GraphQL) can be integrated. Stripe, Twilio, Mailgun, OneDoc, Shopify, SAP, Salesforce... if it's documented, it's integrable. For systems without a public API, a prior discussion is needed.
