Hello

About Us

Welcome to my fascinating world of taxes, sailing, and fast cars! I am a fearless sailor who isn’t intimidated by the turbulent waters of the Polish tax legislation. My professional path is an adventurous journey filled with challenges, and at its core lies my passion for taxes.
I have worked in an international automotive corporation, where I had the pleasure of coordinating the integration between SAP sales system and accounting. However, what truly delights me is eliminating unnecessary and time-consuming processes in my clients’ businesses. I find joy in helping them achieve greater efficiency and simplifying their tax obligations.
I am a lifelong learner, constantly seeking growth opportunities. I have completed two degrees – psychology and law – and pursued postgraduate studies in business management. Currently, I am working on my PhD thesis in international tax law, specifically focusing on the taxation of AI labor. Additionally, I am in the process of taking examinations to become a certified tax advisor.
Life, to me, is a grand adventure that combines my passions for sailing, fast cars, and the intricacies of taxation. I am always ready to face any challenges that come my way on this journey. If you are in search of an expert who can help you navigate the complex world of tax regulations and introduce innovative solutions, I am here to assist you.

Together, we can embark on this exciting tax expedition and achieve success!

Taxes are an interesting and challenging career path. I love the sea, sailing and fast cars, I am not afraid of the turbulent waters of Polish tax legislation. I have worked in an international automotive corporation for 12 years , where I coordinated, among others, CRM systems implementation, which is my another hobby. I enjoy nothing more than the elimination of unnecessary and time-consuming processes in my clients’ companies. I like to learn more, and graduated in both psychology and financial law as well as postgraduate studies in enterprise management. Now I am working on a PhD in international tax law (taxation of robots) and I am currently examining a tax advisor. I treat life as a great adventure.
