In short
DevAndCloud designs and builds custom websites and web applications: corporate sites, e-commerce, SaaS platforms and business tools. We use Next.js, React and TypeScript to deliver fast, secure, search-friendly websites, and you keep full ownership of the code and data.
A website or web app is more than a shop window: it is often your first contact with customers and the core of your operations. We start from your goals (generating leads, selling online, streamlining an internal process) to choose the right architecture and technologies, without over-engineering.
We build in from day one what makes the difference over time: performance, SEO, accessibility, security and automated tests. Your product can include AI features and runs on monitored cloud infrastructure.
You want to…
- Launch a professional website that reflects your brand and generates leads
- Build a web app or a SaaS product from scratch
- Replace an ageing internal tool or spreadsheets that got out of hand
- Improve the performance, SEO or security of an existing site

Frequently asked questions
Yes. We start with a technical audit to assess the codebase, then propose a takeover plan: fixes, gradual modernisation or a rebuild, depending on the case.
Technical SEO fundamentals are built in from the start: performance, server rendering, markup, sitemap, structured data and multilingual versions.
Yes — if you wish, we integrate an admin interface or a CMS suited to your needs.
Next.js, React and TypeScript for the front end; Node.js, NestJS or Symfony on the server; PostgreSQL for data. Standard, widely used technologies, so you never depend on a single provider.
For a simple content site, a CMS may be enough and we will tell you so. Custom development makes sense as soon as you need high performance, specific features, user accounts or integrations with your tools.
Yes. Each language gets its own URLs, SEO tags and copy, so it can rank well in each country.
We set up hosting on your own accounts (cloud or dedicated server), so you keep control of the domain name, access and data.
Both. Fixed price suits a well-defined scope; time and materials suits a product that keeps evolving. We recommend the right option in our first conversation.
