Bharatiya Jyotihshastra (History of Indian Astronomy), translated by R. V. Vaidya v2.c12.s2.t57: Kṛpārāma

v2.c12.s2.t57.1

He has written commentaries with illustrative examples on Bījagaṇita, Makaranda and yantra Cintāmaṇi. He has also written commentaries on the Sarvārtha Cintāmaṇi, the Pañca Pakṣī and the Muhūrtatatva, and there is also a work, Vāstu Candrikā, written by him. This information has been collected from the Aufrecht’s catalogue. The date of Muhūrtatatva by Keśava is about Śaka 1420. So the date of Kṛpārāma must be some year later than Śaka 1420.
