Hi,
I'm Jan.
Freelance Software Engineer
For the last five years I've been working as a developer,
and helped multiple
businesses launch and extend their ideas.
Data Processing
During my time at Adomik, I developed and implemented the core data processing pipeline that integrates data from over 50 different sources. This Data Engine noticeably reduced the number of reported problems, and improved confidence in the processed data.
Technologies: Scala, Spark, Ruby, PostgreSQL.
Full Stack
Web Development
While working for WIF Partner, I implemented a web app that presents their analysis of public buildings to municipalities. This web app makes the findings more visible, and helps WIF Partner to position themselves as a modern forward looking company.
Technologies: PHP, Laravel, Bootstrap, PostgreSQL.
Media Processing
At Storytile, I helped implementing the first version of their backend, helping them process, edit and display the multimedia files of several of the biggest german publishers.
Technologies: Scala, Play, PHP, Laravel, PostgreSQL, Azure.
