Services

What I can do for you

Three areas, one standard: solutions that hold up in everyday use – explained in plain language, with no hidden dependencies.

Programming

Data, code and web – from a single source

Off-the-shelf programs force you into their workflows. I build tools that adapt to you – no complicated setup, no forced subscriptions, and a direct line to the developer. A selection of my own projects:

Data analysis

Scientific precision for your data

Measurement data is only as good as its analysis. As a physicist with a doctorate and more than 15 years of experience in image processing and metrology, I get out of your data what's really in it – documented so you can follow every step, and delivered as a tool you can keep using yourself.

Web administration

Your website in good hands

A website is never finished: content goes stale, dates change, updates are due. I take care of the ongoing maintenance of your site – reliable, reachable and at predictable rates. On request with a fresh design and support for your social media channels.

About me

Physics meets practice

Behind kornelius data is me: Dr. rer. nat. Jonas Kornelius Haunschild, a physicist with a doctorate, based in Vörstetten near Freiburg, Germany. Since 2008 I have been working at the Fraunhofer Institute for Solar Energy Systems ISE. There, I earned my doctorate on novel quality-control methods for solar cell production. Today I lead a research group for inline analytics and production control and am responsible for quality assurance on the PV-TEC pilot production line for solar cells. Image processing, measurement data analysis and software that has to hold up in everyday use have been my craft for more than 15 years – documented in more than 20 scientific publications and three patents around luminescence imaging.

With kornelius data I bring this experience to smaller projects: for small businesses, research teams, communities and clubs for whom big agencies are too much and off-the-shelf solutions too little.

Transparency matters to me: My main occupation is as a scientist at Fraunhofer ISE – kornelius data is a registered secondary occupation. I only take on projects that do not conflict with my work at the institute.
