Throughout my career, I worked as a teammate, Team & Tech Lead, Chief Data Officer, and ML Solutions Architect. Several times I've gathered a team & department from scratch and mentored the participants. Over the years I've had data science projects which involved full-cycle ML/DL model development. I have successfully mentored and managed teams of data scientists & ML engineers (up to 25). Additionally, built and deployed different ensemble models using ML algorithms. My strength as an employee is not only in the model-building participation but in solving the business problem using an ML/DL model with applying full-cycle DS/ML project serving.

I worked in the following areas & with tasks: Computer Vision (Human Pose Estimation: Hourglass, HRNet, Custom, BlazePose, Open Pose, PoseNet, DensePose; Object Detection; Instance & Semantic Segmentation design PoC & MVP); FinTech; Banking (Churn prediction); Energy; Images & Video streaming; NLP (NER with transformers & Spacy, text classification, sentiment analysis, tokenization, lemmatization); image classification; image generation & augmentation, time series analyzing/forecasting (ARIMA, LSTM, FBProphet) classification, clustering, sentence classification; face detection & person identification; Anomaly/Fraud Detection; A/B testing. Have the experience to build projects from scratch: from PoC to MVP (deployment).

What I do at my last workplace:
- implementation of deep learning and classical machine learning approaches on tabular data;
- data wrangling, cleaning, imputting, transforming, scaling, ETL, EDA, anomaly detection, missing data handling, etc.;
- implemented statistical methods to identify trends and relationships between different features & targets;
- feature selection & engineering;
- trained models for insurance (automotive industry) claim  & profit prediction (regression task), claims binary / multiclass classification. time series forecasting;
- usage of the approaches: cluster analysis, pattern recognition, regularisation, dimension reduction, ensemble methods
- model's validation;
- (hyper)parameter’s  searching  &  optimization  (Grid, Random, Manual, Neptune, Autokeras, Optuna);
- planned and built new deployment architectures;
- trained and tuned neural networks (MLP);
- models explanations by different approaches (LIME, ELI5, build-in, SHAP, DALEX).
