Web development in Leiden.

Web development in Leiden means building websites, platforms and software for a city that runs on knowledge, life sciences and healthcare technology. The Leiden Bio Science Park is one of the largest life sciences clusters in Europe, and Leiden University produces a steady stream of spin-offs. Those organizations often work with sensitive research and patient data, which sets requirements for the software around it.

NedDev works as a The Hague studio for clients in Leiden, and Leiden is so close that we almost treat it as a home base. The travel time is under half an hour, so we are quickly on site for a conversation around the table, a design session or a go-live.

For organizations in Leiden we typically build:

• Platforms for life sciences and healthtech where data processing is demonstrably handled properly.
• SaaS products for spin-offs that turn their research into an earning product.
• Easily findable websites for knowledge-intensive service providers and institutions.

Leiden is a knowledge city with a pronounced profile. The Bio Science Park attracts life sciences companies, biotech and healthtech, and Leiden University feeds that with research and spin-offs. Anyone building software here is almost always building for an environment where data is sensitive and care is non-negotiable. That fits our way of working: in production we always have logging, error handling and clear agreements about access.

For life sciences and healthtech clients we build platforms on our multi-tenant SaaS architecture, so data from different projects or clients stays strictly separated. If an AI component is added, such as making research documents searchable, we build that through AI development with source attribution, so every answer can be traced back to its source.

How do you handle sensitive research or patient data? We build privacy and separated access in from the first line of code, with full logging so it is traceable who saw what. For sensitive data we advise, where needed, on storage and models that stay within the EU.

The City of Leiden positions itself emphatically as a city of knowledge, see leiden.nl. How we handle sensitive case files and strict permissions is shown by ClaimHandler, where every action is traceable and users only see what they are allowed to see.

Leiden is so close to our studio in The Hague that we almost see it as a home base. The travel time is under half an hour, so on-site work is not the exception but the norm when it helps. We can easily sit at the table for a kick-off, a design session or a go-live, and we can also drop by in between if a topic calls for it. That proximity makes the collaboration personal and nimble.

We build our websites and interfaces on Next.js, for fast and easily findable pages that also run smoothly on mobile. The backend runs on Laravel. That fixed stack keeps maintenance and further development manageable, even years after delivery, which matters for long-running research projects.

This is how we approach a Leiden project:

1. Kick-off on site to sharpen the problem, the goals and the data requirements.
2. A working design you can see and test, not just read.
3. Building in sprints with a demo each week, so adjusting stays easy.
4. Going live and watching real usage closely in the first weeks.

Around the Bio Science Park new spin-offs keep emerging that register their first company at the Chamber of Commerce. For such young companies a well-defined first platform is the smartest start, and the short distance makes intensive guidance easy.
