His primary patron (and customer) was King Stanisław August Poniatowski. After 1787, he served as a chamberlain at the court.[1] By 1804, he was sufficiently well-off to settle on his own small property near Kozery.
He was renowned for his ability to create small watercolors or gouaches on ivory, using a pointillistic style that created the effect of smoothness.
In addition to portraits of the King, he painted portraits of other European monarchs, national heroes, artists, scholars, and aristocratic families and their friends. He also made miniature copies of the works of Bacciarelli, Josef Grassi and Jan Chrzciciel Lampi.[1]
