Jorrit Steetskamp

Senior full-stack developer of applications and databases
from data to information designs and develops webapplications and databases.
Translation from complex data to readable inforation is the key.
This can be done with ingredients like:
Dashboards with understandable charts
Users with specific access
Create and save reports
User-friendly forms
Data from your systems is a "one man software house".  What does this mean?

  • Management of the full project. My primary task is to finish your project successfully. After 19 years of experience I know what is needed to achieve this. I guarantee a complete end product.
  • More than programming. Let me help you with business analysis and the functional design. Your plan does not need to be crisp and clear before our cooperation can start. The analysis of your request is part of my expertise.
  • No managers and no overhead. You will have one contact during the full process. Even in my role as programmmer communication will have priority.
  • No outsourcing. I will do everything solo. In the unique situation that I will be out of scope, a relation of mine is ready to take over.
  • Always custom-made and developed from scratch. No use of CMS-systems or other templates, and also no licensing or fees.
  • Fixed pricing is possible of course. Advance payments are not needed.
  • Durable cooperation. Clients and I remain partners after delivery.

These considerations will help getting things done:

  • Your project can be fulfilled for a fixed price, as soon as there is a functional design.
  • I also can support your project continiously. With every assignment you will get a meaningful indication of needed hours in advance.
  • I work for multiple clients simultaneously, so our cooperation will be according to Dutch law.
  • Assigments will be planned on a digital scrum board, showing both pre- and post-calculation of hours.
  • Mostly you will become intellectual owner of the source code.
  • Conditions written in the "NLdigital Voorwaarden 2020" apply to my services. You can download them here.

  • Now you read this far, you might be interested in me as a person. My fascination is there where engineering and free expression meet. Think of architecture, electronic music, photography, language or user experience. And I love ice skating, camping, USA cars and last but not least my family.
