[02 November, 2024] Zengqi is very experienced in AI Machine Learning, model mapping and training. He pays special attention to detail and completes projects on time and within budget. A true professional freelancer.
Yu Zengqiy was the worst Freelancer I have ever dealt with. His sole focus was on releasing milestones rather than delivering quality work. He repeatedly pressured both me and my staff to release payments within hours of starting, despite failing to meet any professional standards. His promises were mere falsehoods, and his conduct was unreliable, untrustworthy, and a colossal waste of time. I do not recommend him to anyone, as he lacks both ethical and professional skills.
I recently had the pleasure of working with Zengqi. From start to finish, he demonstrated professionalism and expertise that made the entire process smooth and efficient.
He was available during U.S. hours, both in the mornings and evenings. This made it incredibly convenient for me to communicate my needs and ask questions without any scheduling conflicts.
Zengqi executed the project on time, adhering to the timeline we discussed at the outset.
