Recommendations
Recommendations come from relatives, friends and acquaintances of the tutor
I've known Esmaeil for several years, and he is extremely reliable and professional. He is kind, understanding, and very patient. He is an expert in computer science, and I highly recommend him to anyone looking for a skilled and supportive tutor.
I had the pleasure of teaching Esmaeil Zare in my Algorithms course during his undergraduate studies, where he demonstrated an exceptional aptitude for the subject. Esmaeil consistently ranked among the top students in the class, achieving the highest grade with his deep understanding of complex algorithms and his ability to apply them effectively to solve challenging problems.
Beyond excelling as a student, Esmaeil also worked with me as a teaching assistant for several semesters. During this time, he proved to be an invaluable member of my team. He not only supported students in understanding difficult concepts but also brought a level of enthusiasm and dedication that greatly enhanced the learning experience for everyone.
Esmaeil has a rare combination of technical expertise and the ability to communicate ideas clearly and effectively. Whether helping students during office hours or assisting with course materials, he consistently went above and beyond to ensure their success.
I have no doubt that Esmaeil’s passion for teaching and his mastery of programming and algorithms make him an outstanding tutor. I highly recommend him to anyone seeking guidance in these areas.
I’ve been learning from Esmaeil Zare for the past two years, and I can honestly say he’s been instrumental in my growth as a programmer. When I started, I was struggling to grasp some of the fundamentals of Python, algorithms, and databases. Esmaeil not only helped me build a solid foundation but also guided me through advanced concepts with incredible patience and clarity.
One of the things I appreciate most about Esmaeil is how much he tailors his teaching to your goals. When I began preparing for job interviews, he went above and beyond to help me practice coding problems, refine my understanding of algorithms, and tackle database design questions. His mentorship gave me the confidence and skills I needed to succeed.
Thanks to his guidance, I recently landed a software engineering role at Meta—something I never thought possible a couple of years ago. I owe a huge part of this achievement to Esmaeil and his exceptional teaching. If you’re serious about learning programming and want a tutor who truly cares about your success, Esmaeil is the person you need.I’ve known Esmaeil Zare since our time as classmates during our bachelor’s degree, where we often worked together on group projects. From the start, Esmaeil stood out for his sharp problem-solving skills, deep understanding of programming, and his ability to approach challenges creatively and logically.
Working with Esmaeil on projects was always a rewarding experience. He was not only incredibly skilled but also supportive and collaborative, making sure everyone on the team was on the same page. His explanations were always clear and thoughtful, and I learned a lot from him during those years.
Now, as someone working as a machine learning engineer in Canada, I often think back to those projects and how much Esmaeil contributed to my own growth. I have no doubt that he brings the same dedication and expertise to his teaching. If you’re looking for someone who knows programming inside and out and has a gift for teaching, I wholeheartedly recommend him.I had the pleasure of working with Esmaeil Zare at Atishar, and I can confidently say he’s one of the most knowledgeable and approachable professionals I’ve met. His expertise in programming, databases, and web development is top-notch, but what really stands out is his ability to break down complex concepts into simple, clear explanations.
Esmaeil was always the go-to person in the team whenever someone needed help or guidance. He has a natural talent for teaching and genuinely cares about helping others improve. I’ve seen him patiently walk team members through challenges and make sure they not only solved the problem but really understood the “why” behind it.
If you’re looking for a tutor who knows his stuff and makes learning enjoyable and rewarding, Esmaeil is your guy. I’m sure his students will learn a lot and feel inspired to tackle even the toughest programming challenges.Milad and I collaborated for a few months. Working on projects with him and learning from him was a fantastic experience for me. He's laid-back and teaches in such a way that everything sticks with you. Milad allows you to "get your hands dirty" while teaching you how to approach the challenge. He clearly has a lot of experience and, more importantly, he can effectively pass on his knowledge!
I've been working with Milad for over 4 years. He is a focused, well-organized educator who fosters positive relationships with his students. His ability to connect with his students, as well as his talent for teaching both basic and advanced concepts (in programming languages or other disciplines), is truly outstanding. I strongly recommend him to all Superprof members.
During my undergraduate studies, Milad tutored me in a Python course. He makes every effort to make what he explains as easy to understand as possible. He is passionate about his work, and it shows in his tutoring, where he will assist any of his pupils with their questions. He will work with you to ensure that you are assimilating the teachings as you progress, no matter what level you are at. In his classes, nobody gets left behind!
I've known Milad for over 8 years. He's excellent at explaining exactly what you need! He's not just a knowledgeable programmer. Milad listens to you carefully, understands where your questions come from, then dedicates time and effort to ensure you get your answer! It's almost impossible to get bored at his classes; he's very patient with students and has such uplifting energy. I would strongly recommend him as a Programming tutor!
