Biography

I moved from Kyiv to the United States at 17 due to the war, an experience that accelerated my independence and discipline. Over the past several years I have focused on building a stable foundation through mathematics, engineering, and structured self-improvement. I am currently an Applied Mathematics student with interests in statistical and stochastic modeling, computational systems, and practical software engineering. I am drawn to problems that require both analytical reasoning and implementation discipline. Outside academics, I train regularly, compete in collegiate chess, and spend time repairing or building physical systems. I prefer understanding how things work at a structural level rather than treating them as black boxes. Family, sport, and long-term personal development are central priorities in my life.

My Approach

Professional Philosophy

“I value reliability, clarity, and control in any system I build. A solution is not complete unless it can be debugged, extended, and trusted under stress. I prefer correct structure over short-term shortcuts. Efficiency matters, but only after a system is understandable and stable. My approach is test-driven and model-oriented: identify structure, remove weak points, and iterate until behavior is predictable. Pressure does not disrupt good systems — it reveals them.”

Academic & Technical Focus

Statistical Modeling

Regression, classification, inference, predictive analytics, and probabilistic reasoning.

Stochastic Systems

Random processes, simulation modeling, uncertainty quantification, and probabilistic dynamics.

Machine Learning

Supervised learning, feature engineering, evaluation pipelines, and optimization.

Computational Engineering

Numerical methods, algorithm design, and performance-aware software systems.

Selected Work

Product-level engineering and research systems designed for reliability and scale.

Founder & Full-Stack Engineer

EECAA Platform

Founded EECAA and engineered a full-stack platform supporting 50+ active members. Built custom content management features, role-based access control, event/media workflows, and backend logic for organization operations.

Supervised Machine Learning

Chess Outcome Prediction

Built a supervised learning pipeline to predict chess game outcomes from early-game features extracted from Lichess PGN games. Focused on feature engineering, model comparison, class imbalance, and interpretation.

Unsupervised Learning

Chess Structure Clustering

Explored whether chess games naturally form structural clusters using engineered early-game features. Compared PCA, K-Means, GMM, Agglomerative Clustering, and DBSCAN to study tactical, structural, and opening-family patterns.

Deep Learning & XAI

Chess CNN Explainability

Analyzed a chess-position CNN using Saliency Maps, Integrated Gradients, Grad-CAM, occlusion testing, and stability checks to compare explanation faithfulness and model behavior.

Counterfactual Explainability

Chess Counterfactual XAI

Studied counterfactual explanations for a chess-position CNN by testing how one-piece board interventions change model predictions. Used saliency as baseline and counterfactual search to expose decision-boundary fragility.

Numerical Linear Algebra

PageRank Numerical Linear Algebra

Implemented PageRank as a sparse numerical linear algebra project in MATLAB, using transition matrices, dangling-node correction, damping-factor comparison, and power iteration/direct-solve validation.
