About

Sebastian advises clients navigating complex commercial relationships that span multiple countries and legal traditions. His practice encompasses cross-border litigation, international transport law, and ongoing corporate counsel for businesses with operations across Central and Eastern Europe. Fluency in four languages—German, English, Bulgarian, and Russian—removes communication barriers when coordinating with counterparties, regulators, or local teams. Clients benefit from an advisor who understands both Western European corporate standards and the practical realities of doing business in emerging markets.

His legal career began in Germany following state examinations at the University of Passau, with additional studies at the Federal Siberian University in Krasnoyarsk deepening his understanding of Eastern European legal frameworks. After admission to the German Bar in 2009, Sebastian focused on corporate law and M&A before relocating to Sofia to build LYNX’s Bulgarian presence. A decade of handling international transport matters—including complex EETS toll disputes—has sharpened his ability to resolve cross-border commercial conflicts efficiently. Whether structuring a transaction or steering a contentious proceeding, clients gain a partner who combines German legal precision with hands-on regional experience.
