I had the pleasure of being tutored by Duc and I couldn't be more grateful. He went above and beyond to help me troubleshoot bugs and was incredibly patient throughout the entire session. His knowledge of SQL is exceptional, and he was able to guide me through challenges I had been struggling with. I would 100% reach out to him again in the future and highly recommend his tutoring to anyone in need of SQL expertise!

Duc Duy Bui was an excellent help with my project. He was outstanding at debugging code, understanding the instructions clearly, and knowing exactly what needed to be accomplished. He quickly analyzed the existing code, added the necessary classes, and debugged everything effectively. I definitely recommend his expert advice.
