GODELIAN

Service — Node.js & backend development

Node.js backends that hold up under real load.

Node.js development means building the server side of your product in JavaScript/TypeScript — APIs, authentication, payments, background jobs, integrations, and the data layer everything depends on. Godelian builds backends on the TypeScript/Node ecosystem with Next.js API routes and Supabase (Postgres), with row-level security, idempotent webhook handling, and secure server-side handling of sensitive data. One language across the whole stack means no hand-off between frontend and backend. Shipped in weeks, typically $15–30k, by a founder-operator who owns the architecture end to end.

The backend is where products quietly live or die: the data model, the permissions, the payment logic, and the integrations that simply have to be correct. Get it right and everything above it is easy; get it wrong and no amount of frontend polish saves you. It's the part Godelian treats as the foundation, not an afterthought.

Building on Node/TypeScript with Next.js API routes and Supabase means the same language and types run from the database to the browser — fewer bugs at the seams, refactors you can trust, and no team hand-off where requirements get lost. Row-level security enforces permissions in Postgres itself, so access control doesn't depend on the UI hiding a button.

The hard-won details are built in: idempotent, event-driven webhook handling so a failed payment event is recoverable without double-charging; deterministic code for anything involving money; secure, server-side handling of secrets and sensitive data; and integrations (Stripe, e-signature, email, third-party APIs) done with proper error handling rather than a happy-path demo.

What clients say

We initially wanted to build our MVP with a no-code platform, but Andrew recommended a fully coded solution — and it made all the difference. The product runs fast, scales better, and we fully own the code.

Node.js development — questions

What backend do you build — Node.js, or something else?

TypeScript on the Node ecosystem, using Next.js API routes and serverless functions with Supabase (Postgres) for data, auth, and storage. It keeps one language across the whole stack, scales without server management, and enforces permissions at the database with row-level security.

How much does backend development cost?

A backend for a first-version product at Godelian typically fits within a $15–30k MVP, or is scoped on its own for adding to an existing app. Cost is driven by the number of integrations, the complexity of the data model and permissions, and any compliance requirements.

How do you handle security in the backend?

Permissions are enforced in Postgres with row-level security, sensitive data and secrets are handled server-side only, payment and webhook flows are idempotent so failures are recoverable, every consequential action is logged, and anything involving money runs as deterministic code rather than AI inference.

Can you build and integrate a REST or third-party API?

Yes — building your own APIs and integrating third-party ones (Stripe, e-signature, email, mapping, and more) is core backend work. Integrations are built with real error handling and reconciliation, not a happy-path demo that breaks the first time a call fails.
