Data Structures

Hello everyone!



I'm Dmitry, an analyst with a passion for data analysis that dates back to my university days when I studied economic cybernetics.



Following my graduation, I delved into the analytical realm, gaining diverse experience in sectors such as retail, direct sales, and e-commerce. I've worn multiple hats during my career journey, serving as a sales analyst, marketing analyst, data analyst, product analyst, and currently, leading a team of analysts in an international IT company.



My analytical journey began in 2014, allowing me to accumulate and organize a wealth of practical skills in this field, which I'm eager to share.



No more time to waste—let's embark on the journey to enhance your skills!

I have over three years of experience in IT, primarily as a Software Engineer and working as a SysAdm at present. My professional background spans various projects in computer vision, machine learning, recommendation systems, system administration and monitoring, and automation.



I hold a Bachelor's as well as a Master's degree in Computer Science.



In university and at work like to help others to learn and understand things deeper as it always leads to more cooperation and opportunities to grow together. In teaching, I prioritize clarity and conciseness. My aim is to provide straightforward explanations backed by practical examples as I believe that simplifying complex topics leads to better understanding.

Throughout my career, I have worked in various environments ranging from outsourcing companies to startups, where my role involved managing complex development tasks and systematization. I have successfully maintained a balance between technical and managerial responsibilities. I have progressed from a regular teacher to the head of the Programming and Applied Mathematics departments.



Over the past 7 years, I have applied my skills and experience in the field of IT. I possess a wide range of technologies. Leveraging my PhD degree in engineering and technical sciences, I adeptly translate complex mathematical models into code. My technical expertise includes programming languages such as JavaScript, Python, as well as development on Node.js, database utilization, and other technologies. I am constantly driven to learn and develop, allowing me to stay at the forefront of the IT industry.



With over 25 years of teaching experience in universities and IT schools, I have developed and implemented teaching methodologies that have helped thousands of students learn programming. This teaching experience has allowed me to refine my skills in planning, growth strategies, building effective teams and business processes, as well as quality control.

I have approximately 5 years of experience in the IT industry. During this time, I've been involved in various projects, including computer vision, recommender systems, big data processing, marketing analysis, and other related fields.



I hold a master's degree in applied mathematics and participated in the All-Ukrainian Student Olympiad in Mathematics, reaching the final stage.



My teaching experience spans over 5 years. It began with teaching in a programming club at a school and continued at the university, where I established and led a mathematics and data science club. I like to try simplify complex concepts and explain them in an approachable manner. I take pride in the fact that some of my students have secured positions as data scientists even before completing their bachelor's degrees.

I hold a PhD in Physical and Mathematical Sciences and have a deep passion for mathematics, Data Science, and Python. With an impressive track record of over 30 scholarly publications, some of which are indexed in Scopus, I bring extensive expertise to the table.



My teaching style focuses on delivering complex concepts in a clear and accessible manner, with meticulous attention to detail.
