AI Engineer at 2021.AI developing YOLO object detection models and optimizing computer vision inference pipelines.

At 2021.AI, I develop and evaluate YOLO-based object detection models, preparing datasets for training and validation. I also optimize computer vision inference pipelines and analyze false positives and false negatives.

As a Data Scientist at NDACompanyExperience, I designed an LTV prediction model that reduced marketing costs by up to 15% and automated LTV prediction and anti-fraud processes. At AltexSoft, I led a full-stack insurance project using microservices and a Flask-based backend, increasing policy purchase conversion rates by up to 25%.
