Okay, let’s tackle this. So Virat Talwar has a Master's degree in Computer Science and is a seasoned IT professional. He has experience in leading teams and mentoring junior engineers, which is a valuable skillset. Data science professionals with similar experience and education typically charge around $100–$200 per hour. However, considering his leadership skills, I'll estimate his rate to be on the higher side of that range. Maybe around $125 per hour, which is a reasonable estimate for a data science leader in the United States.
