Do you have a challenging project? I can help you. All my Upwork projects for 9 years completed successfully! I architected and built successfully dozens of complex scientific and industrial projects and I support some of my long-term projects for years. Also, you’d find my open source projects on GitHub including someones which are used by Google Inc. and other corporations and universities.
I'm an Experienced Data Scientist with a demonstrative history of working in the science and research industry. Skilled in Big and Spatial Data processing, Data Exploration, Data Analysis and Machine Learning. Strong engineering professional with a Master's degree in radio physics and electronics focused on nonlinear real world processes modeling from well-known Russian National Research University (UNN), also known as Lobachevsky University.
20+ years of practice in data science and programming engineering in a wide range of projects: from science research in computational physics to complex software products for the real-world problem solutions.
Ask my clients about my data science and time management and communication skills:
"Alexey completed a very complex and difficult geostatistical analysis in a very condensed time frame and generated exactly what we needed. Would highly recommend!"
"Alexey completed this job effectively and very efficiently! His communication on coding plans and progress was fantastic, and he helped me to meet a tight deadline. I would be happy to work with him again in the future and I very highly recommend him to anyone considering hiring him!!"
"Alexey was able to solve mathematically technically difficult project involving implementation of an optimizing algorithm. Did own research and made many valuable suggestions. A great job."
"Alexey is a very talented resource. He was able to quickly understand our business problem and provide a working solution the FIRST time. There was no back and forth. He designed the solution to be future proof. Top notch guy!"
"Alexey is a super developer. Very responsive and diligent. I truly enjoyed working with him and will hire him again and again."
"Does what he says and does it on time. Very strong professional."
"Alexey is a contractor of the highest calibre. He completed a large, highly complex project that four other contractors were unable to; completed it on time; and improved the project's initial goals, surpassing our expectations. Alexey was also very communicative throughout the project, and delivered before the deadline. I recommend Alexey without reservation, and look forward to working with him again."
