My name is Bartek. I am a husband, father of three children, and a freelancer who loves to solve various problems using programming and data.

I have been a lover of mathematics (school competitions, Kangurki, Mathematical Olympiads) since I was a child, which is why I chose mathematics. In 2012 I graduated from the Faculty of Mathematics and Computer Science of the Jagiellonian University (Applied Mathematics). In mathematics, satisfaction with problem solving attracted me the most. In school times, these were mainly mathematical puzzles, but later more abstract issues appeared.

In 2011 I started working as a data analyst at HTA Consulting. When real data appeared, the passion for solving abstract problems shifted to real issues. In this position, I had the opportunity to develop my programming skills in VBA and R. After a few years, I became an independent specialist. I was involved in process improvement (writing tools accelerating data analysis and creating HTA reports). At that time, I got to know new tools such as Python, Git, and Docker, which I work with every day.

Since 2017, I have my own business (Data Scientist Bartosz Sękiewicz) focused on work automation and broadly defined data analysis. I devote most of my working time to the development and maintenance of the IKAR PRO platform. Also, I provide services to clients of such a portal as UPWORK, FIVERR, OFFER. You can find more about my professional experience on LinkedIn.

You can find information about my portfolio at this address. There is information about most of the projects that I realized. Due to “sensitive data”, write to me if you want to get the access password.

Privately, I am a lover of new technologies, and I’m also interested in survival. For several years I actively participated in creating the community of R enthusiasts in Krakow names eRka. I have been the vice-president of the Why R? Foundation since 2018.

If you are interested in cooperation or in any way I could help you, write to me or call (+48 721011501).
