Product analyst, Data analyst

Kyiv · $1700 · 8 years of experience · Advanced/Fluent

For the past 8+ years I’ve been working as a business consultant at EY (Ernst & Young) in Kyiv, Frankfurt a.M., and Hamburg. Though my primary focus lied in the field of tax and reward advisory, I actively participated in cross-functional projects of different scale. Due to my fast learning skills I gained comprehensive knowledge in business performance improvement, process reengineering and organizational design, as well as due diligence and assurance matters. As a rule, my role combined continuous project management and direct delivery on scope and ad hoc tasks, and I was engaged in several simultaneous projects at a time. Research and analysis were always my biggest passions in work, and I excelled in data-driven tasks involving modelling and automation. Recently I realized I want to shift my professional focus from consulting to industry, and I am primarily focusing my effort on a challenging analytical product-oriented role. I’m highly confident that my proven track record of successful diversified analytical projects and extensive client-facing experience, as well as solid autodidactic mindset and exceptional attention to detail will make me a valuable team asset. My CV and reference letter provide additional details of my professional qualifications, and I really look forward to discussing mutually beneficial cooperation.

As a member of a data science team of 4 members I took part in the development of the OSINT system, which is widely used by military structures. I was responsible for creating modules for processing textual information: text summarization, keyword extraction, named entity recognition, sentiment analysis. I built a face recognition system, which is able to detect and recognize faces of 100+ people in both visible and infrared spectrum. NLP: text summarization, keyword extraction, topic modelling, sentiment analysis, named entity recognition, text classification. CV: optical character recognition, license plate recognition, face detection/recognition.

Data Scientist Engineer

Lviv · $1200 · 1 year of experience · Advanced/Fluent

I was working on Computer Vision team on such tasks: - Ball detection and tracking on videos of basketball matches. We are using YOLO v3 and SiamMask. - Action detection: shoot, pass detection. We are using RGB-based and optical flow action detection, with precision 82% and f1 score 72% for shots. Make visualizations using Altair. My English level is C1 on IELTS.

Python, Scrum, Pandas, Jira, Git, JSON, PyTorch, Jupyter Notebook, OOP, Linux, Statistics, Matplotlib, Machine Learning, Data Science, Data Visualisation, NumPy, scikit-learn, Tensorflow, Deep Learning, SQL, Keras, NLP, Computer Vision, English, Docker

I produce basketball analytics about players based on the videos. My part was the ball tracking, we get precision 50.4%, and f1 is 50.4%. It isn't a big score but on 10% - 15% of videos it can't be visible by the person, because sometimes the camera is moving too fast and the entire picture is blurry, on other frames the ball is too blurry. For improving we need better video quality. Then, we start working on action detection; we have precision 82% and f1 score 72% for shots. It happens that some passes that go through all basketball courts are predicted as shots. We are still working on improving this detector. I had more research experience when I was in Prague, working on TextTopicsNet related project. I found it interesting to split big, not understandable topic to smaller pieces and learn one by one. My math knowledge helps me a lot during the research journey.

Like to work in a team.
