We provide tailor-made software development and maintenance

For backend development, we use Python, frameworks, and libraries: Django, Wagtail, Oscar, and others. For frontend development, we use the latest tools: HTML5, SASS, Webpack, Babel, and React.

Quality assurance is a prominent part of our work. We write automated tests, review pull-requests, and apply continuous integration. We are ISO 9001, ISO 27001, and NEN 7510 certified.

We can develop software for you, or assist your development team.
