 After a few years of teaching mathematics in Warsaw he was sent to Rome (Roman College) for further specialization in Architecture (1762–65).Back in Poland he was appointed to teach science at Polatsk (1765–68) but he made himself a name rather as architect of public and ecclesiastical building, including the construction of new premises for the Jesuit College of Polatsk (of which Stanislaus Czerniewicz was the Rector).After the Suppression of the Society of Jesus (1773) he became the right-hand man of the Vicar Czerniewicz, negotiating with him the survival of the Jesuits with Empress Catherina the II of Russia, all the while making sure that the standard of scientific education in Polatsk remained high.
