Olena Sawenko – Founder and CEO of Trans‑Lex

In 2000, I moved to Warsaw, where I began my education and professional career, focusing on building bridges between Poland and Ukraine.
From 2004 to 2012, alongside my studies, I actively supported Polish companies in establishing branches in Ukraine and helped Ukrainian businesses start operations on the Polish market. Thanks to my commitment, both sides could successfully develop their initiatives, drawing on my knowledge and experience in international economic relations.
Education
I am a graduate of the University of Warsaw, where in 2007 I obtained a Master’s degree in Ukrainian Philology at the Faculty of Applied Linguistics and East Slavic Philology. In 2009, I also completed journalism studies at the Melchior Wańkowicz School of Journalism. My passion for supporting international cooperation led me to further education – in 2010, I completed postgraduate studies in European Law at the University of Warsaw, and in 2012, management studies at the Warsaw School of Economics.
Driven by my passion for international cooperation, in 2009 I took part in a series of trainings on the legal aspects of running a business in Ukraine, organized by the Polish‑Ukrainian Chamber of Commerce.
Experience
From 2013 to the present, I have been actively supporting foreigners in Poland, particularly Ukrainian citizens in adapting to a new environment, including representing them before a wide range of public administration authorities and ensuring respect for their statutory rights when handling formalities, especially those concerning legalization of stay, employment, running a business, and education in Poland.
Taking the oath as a sworn translator
A key moment in my career was being sworn in as a sworn translator of the Ukrainian language in 2016, which enabled me to broaden my competencies in supporting Polish–Ukrainian cooperation. I was entered on the list of sworn translators maintained by the Minister of Justice under number TP/3/16
Passion
My passion for supporting the development and integration of individuals and businesses from Eastern Europe in Poland has accompanied me throughout my career. I believe Poland and Ukraine complement each other, and I intend to actively promote this cooperation by helping to build lasting and valuable relationships between our countries.
I also engage in Pro Bono work by providing free services to victims who cannot afford service costs and who clearly need such assistance.
