Web applications
Portals, dashboards, internal tools and SaaS products: applications with users, permissions, data and workflows, built on Next.js and Node.js and connected to the systems behind them. If you need a marketing site instead, that's Website Development.

Businesses that run on what we built
What we build
Accounts, self-service, documents, orders, subscriptions, on top of Odoo or a custom backend. Freiburger Bund's member portal serves physicians in four languages.
Operational and management views over live data (profitability, workload, order status) with role-based access.
The admin and operations screens that replace spreadsheets: approvals, planning, catalog and content management.
Multi-tenant applications with subscriptions and billing. WaveContact's digital business card platform runs on Odoo with Stripe.
Next.js storefronts on Odoo, Shopify or WooCommerce backends.
Distributor onboarding, quotation self-service, certificates and order tracking, as at Hi-Tech Alloys and LittleQ.
Technical expertise
Website or web application?
The most common point of confusion, answered in one table.
| Website | Web application | |
|---|---|---|
| Purpose | Explain, persuade, be found | Do work: transactions, data, workflows |
| Users | Anonymous visitors | Logged-in users with roles |
| Content | Pages, articles, editable by marketing | Records, documents, live data |
| Business logic | Minimal (forms) | Central |
| Integration | Analytics, forms, CRM lead capture | ERP, payments, APIs, other systems |
| Typical stack | Astro + headless CMS | Next.js + Node.js/Odoo + PostgreSQL |
| Page | Website development | This page |
Many businesses need both, and they can share a design system, but they're different builds with different economics.
Delivery
Users and roles, the workflows the application must carry, the data it owns and the systems it must talk to.
Data model, permissions, API shapes and integration points, written before the first screen.
Components, auth, environments and CI, so every feature after is built on rails.
Usable slices each sprint on staging with real data. Feedback from the people who will use it.
End-to-end tests, load testing, security review, accessibility pass.
Production with monitoring. Continuous delivery under an ongoing engagement.
Evidence
A four-language member portal with real-time chat, a subscription SaaS, and Odoo-backed customer and support portals.
Healthcare association & career portal
A medical association platform where Odoo 18 Enterprise is the business backend behind a Next.js 15 web portal, React Native (Expo) iOS/Android apps, a Socket.IO messaging server and MeiliSearch: in German, English, French and Arabic.
SaaS: digital business cards
Digital profile and contact-sharing platform where Odoo runs subscriptions, orders and the store behind a web frontend and a Flutter mobile app, with Stripe recurring payments, Google integrations and vCard export.
Cloud managed services
Accounting, HR and payroll, projects and timesheets, subscriptions, helpdesk and CRM on Odoo 18 Enterprise, with custom modules migrated from earlier versions and financial reporting built for a recurring-services business.

A website explains and persuades people who have not logged in. A web application does work for people who have: transactions, data, workflows, permissions. So if people need accounts and the system changes data, you need a web application, and if you need to be found and to publish content, you need a website.
Yes: that is most of our portal work. Odoo stays the system of record. The portal reads and writes through an API layer we build, with Odoo's own permissions respected.
Both. An MVP is built on the same foundations so it grows into the product rather than being rewritten: that is the point of the architecture-first approach.
Next.js and React with TypeScript on the frontend. Node.js (and Python/Odoo where it's the backend) with PostgreSQL behind GraphQL or REST APIs.
Yes. Freiburger Bund runs in German, English, French and Arabic with real-time messaging and presence on Socket.IO and Redis.
Yes, on the same API: the web application and the mobile app share one backend contract.
Next step
Tell us who uses it, what it must do and what it connects to. We'll propose the architecture and a first release you can put in front of users.
