“I had the pleasure of working with Sai while he helped us build an MVP for a real-time AI interviewer platform. He consistently demonstrated strong technical ability, resourcefulness, and a willingness to take ownership of complex challenges. Sai is proactive, thinks creatively, and works through problems until he finds solutions. He was a reliable and valuable contributor to our team, and I would confidently recommend him to any organization.”
