About our Founder
Jacek Aleksander (pronounced 'Yatzek Alexander') graduated from the University of Gdansk in 2009 with a Master in Computer Science. A member of the Quantum Information group at the Institute of Theoretical Physics and Astrophysics, he wrote his Masters dissertation under the supervision of Professor Marek Żukowski, the 2013 winner of the Foundation for Polish Science Prize. Jacek investigated topics in Bell nonlocality and defended a thesis entitled "Nonclassical Properties of Multiqubit States Applicable in Quantum Information Science." This work required lots of Scientific Computing and it is then that Jacek took his first steps as a Computational Scientist.
Following this experience, Jacek joined Kainos, an Irish software company, and then a Belarusian-American software services company called EPAM Systems. These were his core experiences in Software Development, where he took on numerous roles as a Software Engineer, Senior Software Engineer, Business Analyst, Scrum Master and Technical Support in Presales. His experience also involved short stints at Morgan Stanley, Citigroup and Bloomberg in London, where he worked for Infrastructure Departments on Financial Software.
Jacek founded Jagan Solutions in 2016. The company has since developed into an independent unit delivering solutions in AI, Machine Learning, Data Science and Analytics as well as Scientific Computing and Optimization. Jacek has recruited the best of the best in their trade, which typically revolves around Machine Learning, and makes sure that all projects are delivered up to the highest quality standards. It is his ambition to create a rewarding workplace for Jagan's employees, to provide innovative and reliable services for its clients, and to maintain a steady course on the state-of-the-art science applications in business.
Having worked on scientific problems in the Quantum Information department at University of Gdansk since graduating in 2009, Jacek returned to his alma mater to pursue a PhD in 2017. In September 2019, he successfully defended his dissertation, entitled "Solving Two-Level Optimization Problems Related to Bell's Theorem." He subsequently completed a postdoc at the University of Gdansk, also in the quantum space. Finally, on a year-long stay in the US from 2022 to 2023, he completed the Fulbright Senior Scholarship at Columbia University in the City of New York. His work embraced Computational Mathematics and Bell inequalities.
