As a freelance data scientist at Mql5.com, I develop and implement algorithms for trading in the Forex market, achieving profitable results and high customer satisfaction. I have mastered the art of customer engagement, delivering more than 70 successful orders in the past four years.I have also participated in various data science and machine learning projects, such as creating sophisticated models for image classification, securing a top 3% position in a Kaggle competition for machine failure prediction, and leveraging reinforcement learning for game development. I have a strong background in Physics, which contributes to my skills in data analysis and programming. I am currently pursuing my bachelor's degree in Physics at Belarusian State University, where I learn about the mysteries of the universe and apply my knowledge to solve real-world problems. My interests revolve around machine learning and data science, as well as unraveling the mysteries of the universe.

Python DeveloperDatainsight Aug 2023 - PresentKrakowski, Małopolskie, Poland -
Data ScientistSelf-Employed Jan 2021 - Jul 2023Minsk, BelarusPyTorch course ZeroToMastery• Created sophisticated models for food, clothing, and numerical image classifications, yielding accuracies ranging between 97-98.5%.• Increased overall accuracy by 8-9% through effective utilization of data augmentation techniques.• Acquired comprehensive knowledge of state-of-the-art machine learning algorithms.Machine Failure Prediction• Secured a position within the top 3% in a Kaggle competition• Developed a predictive model for machine failure based on parameters such as current CPU and air temperature, usage time, etc., achieving an AUC-ROC metric of 0.98.• Enhanced model performance by data preprocessing. To address the unbalanced dataset, I implemented oversampling, culminating in a total AUC-ROC metric improvement of +0.18.Reinforcement Learning Snake Game• Leveraged reinforcement learning principles to develop an autonomous Python-based snake game, achieving a minimum score of 20 points post-training.• Employed policy optimization techniques to enhance the game’s performance, resulting in a remarkable mean score increase of 10 points.Protein Dataset Analysis• Conducted a comprehensive analysis of a protein dataset to identify the most influential features. Leveraging this analysis, I successfully trained a model to predict protein types, achieving an impressive AUC-ROC score of 0.96.• Employed sklearn library to optimize the model’s hyperparameters. This resulted in a growth of AUC ROC score, with an improvement of +0.12. Additionally, the training time was significantly reduced by 56%.Python Game Development Expertise: Neon Square and Pixel Fight• Utilized Python’s OOP capabilities to program engaging games - Neon Square and Pixel Fight, available on Play Market. These games have amassed 1500+ downloads, full self-deployment from start to finish.• Implemented efficient code optimization techniques to ensure compatibility across various devices, boosting the mean frames per second by 40%.
