Senior Software Architect, Data Science, Machine Learning

My main skills are software architecture design and leading complex projects from start to successful implementation. It is my pleasure to solve complex tasks and build sophisticated automotive systems. During over 10 years in programming engineering I have gained a huge experience in different areas of computer science. At this moment I mostly focused on data science projects. So I will be happy to help you to bring to life your innovative ideas.

The aim of the work was the search and implementation of an effective algorithm for optimizing the composite material layup for obtaining a minimum weight aircraft structure under the strength constraints. A comparative analysis of several optimization algorithms was carried out. A variant of a modified simulated annealing algorithm was proposed and implemented. This approach significantly reduced the calculation time compared to the initially used branches and bounds method.
Composite material layup optimization
The aim was to find statistical effectiveness verification of the new methods of therapy of chronic pharyngitis according to the results of clinical analyzes. To obtain a quantitative assessment of the patient’s health status, a neural network based tool was developed and trained on historical archival data on the course of the disease in patients. Next, software that evaluates the statistical significance of the difference in the clinical analyzes results of several groups of patients using statistical criteria was written in Python. This helped to prove that indeed new treatment method has better outcomes and is not the result of the scatter of the test scores in different patients within the group.
