"Manish has been Crossmint's first security engineer hire and played a pivotal role in strengthening our company's security posture from the ground up. His expertise in security testing, compliance, and internal operations significantly accelerated our journey toward SOC2 compliance. I highly recommend Manish for any team seeking a dedicated and skilled security professional."
"Manish was one of the pivotal members in the early days of the Synapse team and a highly skilled web security specialist. He receives my highest recommendation. I am very impressed with his work ethic and his passion for security engineering."
"He quickly came up with a detailed test plan and finished the audit in a couple of weeks without much input from our side. It greatly helped us in improving our security standards. I would really recommend Manish."
