Developer

A developer who turns data work into software.

A developer builds the software around data: internal tools, connections, modules and applications that take over or speed up the work of teams.

You deploy a developer when a spreadsheet or a manual process has outgrown what it must do, or when an idea has to become a working application.

This is what our developers build: Custom software, with its own product page on what you get and what it costs.

Through NewData you hire a developer temporarily from € 70 per hour excluding VAT, dropping to € 60 for larger assignments (scale of August 2026) through secondment, take one over through DetaVast or recruit one permanently through recruitment and selection.

The work

What does a developer do?

A developer writes software that keeps working when the builder leaves: tested, documented and transferable. That can be a connection between two systems, an internal tool or a full module.

At DoubleSmart, NewData built a working module in which client data and AI flag marketing bottlenecks and translate them into usable advice.

Do you work as a developer yourself? The rates on this page are what the client pays, not what you earn; what you earn is at for professionals.

Questions

Frequently asked question about this role

When do I hire a developer instead of a data engineer?

Choose a developer when the end product is software: an application, a connection or a module people work with. Choose a data engineer when the end product is the data flow itself: pipelines and platforms that deliver data reliably. In larger projects both roles work side by side, each on their own half.
