Ruslan Zhubanov was a successful student in Sharafatdin Yessirkepov's instrumentation courses at APEC in Kazakhstan. While Ruslan did not have extensive industry experience, he tried his best and was always looking to learn something new by discussing with other students and doing extra practice and work in the laboratory on weekends. Ruslan also worked to simplify complicated course material by discussing with Yessirkepov. Yessirkepov believes Ruslan is friendly, helpful, and can have a good career, and recommends him for opportunities.

Re: Ruslan Zhubanov
Letter of Recommendation
To whom it may concern,
I have written this Reference letter for the benefit of Ruslan Zhubanov. When I was teaching the
Instrumentation courses at APEC (Atyrau Petrotechnical Educational Centre ) in Kazakhstan, Ruslan
Zhubanov was studying in the class of SPT (Specialized Petroleum Technology) program. He studied the
DCS (Distributive Control System) and he was successful in my course.
Ruslan Zhubanov tries to do his best in APEC, even though he has not worked in the industry too much.
Every time he intends on learning something new and discussing with other students. Ruslan has
improved his knowledge by practicing a lot with process control system and doing extra works in the
laboratory, even on weekends.
The books of Instrumentation look complicated for the high School students, but Ruslan tries to simplify
them by discussing with me. He tries to work with the lab equipment to get the practical knowledge.
I think that Ruslan Zhubanov is friendly and helpful and he can make a good career. If you have any
questions, you are welcome to contact to my e-mail address.
