Data Science, ML, Big Data Engineer, Python, Data Warehouses

Experienced, team player, good communicator. Effective problem solver. Data scientist and machine learning programmer and engineer. Mathematics degree and MBA. Experience building predictive models and doing regression analysis and clustering. Knows how to install, configure, and load data into different Big Data and SQL databases. Experienced with data warehouses. Knowledge of UNIX systems administration. Some projects: ✔ Sales Forecasting with Keras Developed a deep neural network in Keras to predict monthly sales for a retail chain using historical sales, promotions, and economic indicators. Implemented feature engineering and regularization techniques to improve model robustness. Achieved significant improvements in forecasting accuracy, supporting better inventory planning. ✔ Equipment Failure Prediction with PyTorch Built a PyTorch-based neural network to predict equipment failures in a manufacturing plant using sensor data and maintenance logs. ✔ Invoice Document Classification using Transformers Fine-tuned a transformer-based model (using Hugging Face Transformers) to automatically classify scanned invoice documents by vendor and type. ✔ Image-Based Defect Detection with Neural Networks Engineered and trained a convolutional neural network to detect surface defects in industrial products from high-resolution images. Leveraged both Keras and PyTorch frameworks to compare model performance and optimize for speed and accuracy. ✔ Machine Learning Textbook Authored Machine Learning programmer’s guide, explaining algorithms for linear/logistic regression, probability distributions, and neural networks using Keras and scikit-learn. Included practical examples for K-means clustering and classification, tailored for developers transitioning into data science. ✔ Teach Python, Keras, PyTorch, Statistics For two years I have been teaching Ukrainian university and college students neural networks, matplotlib, Pandas, Numpy, Keras, statistics, and PyTorch. I do this 2 hours per week, free.
