Unrivaled Excellence: Richard Mantik, the Pinnacle of Tutoring
There is no amount of gratitude that one would say goes to show truly how grateful I am for the outstanding help and support that Richard Mantik has given me in this journey toward becoming a software engineer. His explanation and the way he teaches SQL, JavaScript, HTML 5, and CSS are superb.
Richard is a "perfect blend" of motivation, inspiration, and, of course, technical expertise. He is an enthusiastic teacher, having helped many students understand the classwork as a tutor and lab demonstrator at the University of New South Wales. His real-world experience applies so much value to the lessons and he is always able to make even the most intricate concepts seem doable.
Many thanks to Richard, who really helped me to fine-tune my technical skills, and I could come out with a fresh, confident face to struggle with tiredness from projects and assignments. His love and passion for Mathematics, Algorithms, AI, and Software Engineering are bound to pass on to the students so that he loves to see them successfully placed in their careers.
I recommend Richard Mantik very highly to anyone who would seek a mentor or tutor for their professional work or studies in any area of software development. He is not a teacher, but in fact, he is a mentor who really cares for the growth and success of his students.

Tutoring
Richard Mantik was SO AMAZING. He helped my son with his Web database (PHP, MySQL, HTML/CSS/Java script) development course and made everything so clear. He knew his stuff inside out and always explained things in a way that my son could understand. Plus, he was super friendly and always there to help, which was a lifesaver when dead lines are looming. Thanks to him, my son’s grades shout up,and he actually started enjoying the subject. If you need a top-notch tutor who really cares about tutor child’s success, Richard is the one to go for!

Tutor is very friendly and is knowledgable
The tutor is extremely friendly and goes an extra mile to make sure you understand the code as well as to ensure the code is as efficient as possible. He does your projects right away with the mindset to achieve the best possible outcome and not just for the sake of finishing it. I recommend him 100% with no hesitation if you want the best and caring tutor who is brilliant as well!

An emphatic tutor who cares about teaching and learning.
Richard is an exceptionally dedicated and proficient tutor. He demonstrated remarkable responsiveness and ensured that I could understand the subject and grasp the program or code. All of this happened even before starting the session, and before concluding the session he made sure that I could work independently in the near future. He is engaging and shows empathy while working with you, which reflects his extensive expertise in other subject areas such as span software, coding, and programming, enriching the learning experience.
I will highly recommend Richard if you want to have an engaging experience and learn with someone ready to share without thinking of anything else.

Data Structure Tutoring
Richard’s a good data structures and algorithms tutor. He supported my learning of leetcode problems where I learnt a few techniques to optimise my code, for an interview. I would recommend

Explains algorithms and data structure concepts in understandable way
I have had a session with Richard and he had patience to explain to me about efficiency algorithms and walked me through their implementation in Python; He was not afraid to debug when things went wrong and is a competent programmer;
