Web application development
We build MVPs, client portals, internal tools, and dashboards as custom software. We work remotely with founders and teams in Morocco, France, and the rest of the EU, in English or French. You get a written scope, a staging link from the first week, and full ownership of the code at the end.

Is this you?
If two of these sound familiar, a custom web app is worth a conversation.
What you get
Every package is scoped in writing before you pay anything. These parts appear in all of them.
Sign-in, password reset, and roles that control who sees what, built in from the start.
A back office designed around how your team works, so day-to-day changes don't need a developer.
We design the database before the screens: relational data on Supabase, with tracked migrations so future changes are safe to make.
APIs, webhooks, and imports that connect the app to the tools your business already uses, such as accounting, email, payments, or your own systems.
A staging link from the first week, every release tracked in Git, and a way to roll back. You see progress every week, well before launch day.
We transfer the repository, database, and hosting accounts to you, along with documentation written for whoever maintains the app next.
How we build it
The same four steps on every web app project, from a one-screen MVP to a multi-tenant platform.
A short call about your goals, users, and budget, followed by a written scope.
Wireframes, a technical plan, and a phased delivery schedule.
Weekly progress on a staging link, adjusted to your feedback.
Go-live, team training, and optional ongoing support.
Technology
Widely used and well documented, so another developer can take over the project later without rewriting it.
The application framework. Server rendering for speed and SEO, file-based routing, and one codebase for both your marketing pages and the product.
The interface layer. Screens built from reusable components, which keeps the code maintainable as the product grows.
APIs, background jobs, and business logic on the server, written in the same language as the front end.
Vercel for hosting and preview deployments, and Supabase for the database, authentication, and file storage. Both accounts are transferred to you at the end.

Client work
Two teams whose daily operations now run on software we built.
“Codinou built the platform our network of veterinarians relies on every day. Registrations, health records and pedigrees that were handled on paper are now centralized and instant. Clean work, delivered exactly to spec.”
“Codinou delivered exactly what our transport business needed: a fast, reliable platform our team and clients actually enjoy using. Clear communication from the first call through to launch.”

What founders ask before the first call.
Send us a paragraph or a full specification. Either is enough for a first answer on scope, price, and timeline.
