Testimonials
What colleagues and collaborators say.
During Utshab’s tenure as a smartbook writer at 10 Minute School, he was frequently assigned responsibilities for writing and reviewing smartbooks. He was a quick learner, and there were numerous occasions where he proved his skill at both independent and collaborative work. His proactive and self-motivated nature made him a valuable asset to our team. He is a well-spoken and intellectual individual.
Utshab is a polite yet cheerful person with a passion for music and computer science. He is hard-working, keeping his programming fundamentals strong through competitive programming while also working on machine learning, Django, PyGame and more. As co-founder of the software startup Code Studio, he has proven his leadership and development skills. His skill set can be an asset to any company that makes the best use of him.
I have known Utshab for a long time. In those years, I have seen him excel not only at the core elements of data science and machine learning, but also at skills and tasks that extend well beyond the scope of his role. His sense of responsibility and his mastery of both can be critical to any team’s success. I have only optimistic predictions for his career trajectory.
Utshab is a hard-working person, enthusiastic about learning new things, with profound knowledge of machine learning and data science, which he shares with aspiring data scientists through his ML Bootcamp program. He works with me at Code Studio, where his leadership stands out. He is a good mentor, a creative person and, above all, a helpful friend.
