In 1591, he helped reconstruct the nave and apse of the church of Sant'Anna dei Lombardi. He also succeeded Francesco Grimaldi in the direction of the construction of San Paolo Maggiore.

From 1598 to 1599 he helped design the Cappella del Tesoro in the Basilica of the Santissima Annunziata Maggiore. In these years, he accused the foreign rival in Naples, Domenico Fontana, of selecting a poor site for construction the Royal Palace.
