Our team

Meet our team of awesome professionals

Krzysztof Antoniak

Junior Software Engineer

I work full-time on frontend and backend development. I’m always willing to pitch in wherever I’m needed, whether that means implementing a new feature, making improvements or just bugfixing.

How things work makes me curious, but I like when everything has its own place.

I adore movie scores (007 is my favourite movie series) and I play the guitar a bit. I also enjoy reading about ancient history.


Jarosław Błąd


Every day I apply my over fifteen years of experience in relational databases, internet application development and software teams management to make Vertabelo the best application of its kind.

I’m a big fan of the creativity of Stanisław Lem and Philip K. Dick.


Patrycja Dybka

Community Manager

I’m a growing blogger and tech lover. For Vertabelo, I provide support including writing technical blog posts and articles and handling Vertabelo’s social media profiles.

I’m passionate about Latin dances – I love to watch and put all of my energy into hours of dancing. I’m also having fun improving my climbing skills through bouldering.


Michał Kołodziejski

Chief Technology Officer

I’m coding new Vertabelo functionalities, repairing “unwanted features”, and investigating server and application logs when something unexpected happens.

In my spare time, I love playing pool-billiards and snooker.

Besides that, I like reading books by smart and wise people from all over the world and logging hundreds and thousands of kilometers on my motorbike.


Agnieszka Kozubek-Krycuń, PhD

Chief Scientist

As the editor-in-chief of Vertabelo blog, I collect ideas for new articles, look for new authors, and work with them on new articles.

I also prepare SQL courses for Vertabelo Academy, answer the questions asked by its users and explain the theory behind relational databases.

In my free time I teach programming courses at the University of Warsaw. After hours, I read way too many books and attend way too few yoga classes. To wind down, I go mountain hiking in Slovakia.


Łukasz Kubicki

Head of New Business

As a Head of New Business and an Executive Board Member I’m responsible for all the company’s activities concerning searching for and developing business opportunities including new partnerships.

I try to spend most of my spare time with my family. If there is some time left I usually spend it in my garage restoring an old (1962) Volkswagen T3 1500 Variant. In the summertime, I love to sail and during the winter I sneak out for snowboarding.


Adam Mościcki

Junior Software Engineer

I’ve been a member of the Vertabelo team since April 2015. As a junior software engineer I support the technical staff in developing our application and its new features. I’m also a co-author of Vertabelo Academy.

I am interested in modern technologies especially the ones connected with computer science. I am an avid Counter Strike Global Offensive player. In order to keep a balance between work and life I spend my spare time on cycling and running. I also love watching football and ski jumping.


Olaf Pietrewicz

Front End Developer

As a front end developer, I’m responsible for creating and implementing all of the visual elements that Vertabelo users see and interact with. To do this, I utilize my long experience in image editing, HTML, JavaScript, and CSS.

I’m a lover of science fiction, Giger’s Alien, Star Wars, The Prodigy, Daft Punk, vintage Hi-Fi, Lego bricks and definitely Star Wars Lego bricks :)


Paweł Poskrobko

Junior Software Engineer

I’m passionate about learning so I’m always keen to interact with new technologies, tools and techniques. I’m a functional programming and pragmatist software engineer advocate.

I constantly look for the new challenges and never consider giving up to be an option.

I’m curious about the world around me and try to understand it better and better. As an avid traveller, I’d like to set foot on every continent (Antarctica included!). In addition, I’m an Indian cuisine lover, cold wave music fan, civil aviation enthusiast and hobby researcher on Caucasus and Central Asia politics.


Rafał Strzaliński

Senior Software Engineer

I’m proud to be one of Vertabelo’s originators. Having over 15 years of experience in software development, I’ve been doing my best to make Vertabelo useful for a wide variety of people.

I love traveling with my family, riding a dirt bike, and talking with my friends for hours. I also like beef, making jokes, and not taking life quite so seriously...
