PROFILE
I am a 3rd-year Software Engineering student with 2.5 year of professional experience as an ML Software Engineer and Classic
ML Engineer. My background combines Full-Stack development (.NET, React, SignalR) with a deep expertise in building end-to-end
ML pipelines - from intelligent data collection and preprocessing to deploying RAG systems and transformer-based models.

EXPERIENCE
E-signature platform Python, FastAPI, RAG, MInference
ML Software Engineer Jan 2025 - Dec 2025
• Architected a scalable REST API using FastAPI with Dependency Injection patterns and strict data validation through Pydantic
• Implemented a Hybrid Search architecture in Elasticsearch, combining vector embeddings with structured metadata for deter-
ministic filtering
• Optimized document processing by implementing a recursive chunking strategy with overlap, significantly improving context
retrieval quality for semantic search
• Used MInference to optimize the calculation of attention matrices in documents with long context, which resulted in reduced
memory consumption and latency.

UKRSIBTECH (Outstaff Project) Python, XGBoost, Random Fores, Scikit-learn, SMOTE
Classic ML Engineer July 2023 - Nov 2024
• Implemented a fraud detection system (Anti-Fraud), achieving a high Precision indicator with a low proportion of the target class
(Imbalanced Classes)
• Automating the analysis of customer sentiment in social networks and chats, achieving a high F1-score
• Developed a full lifecycle of ML models to prepare data for deployment, which reduced the time to release updates

Internet Messenger .NET Core, React, SignalR, PostgreSQL
Full-Stack Developer (pet project) Feb 2022 - Apr 2022
• Developed REST APIs using ASP.NET Core and designed database schemas for CRUD operations.
• Implemented real-time messaging, chat features, and user statuses using SignalR.
• Managed application state with Redux Toolkit and local data storage with IndexedDB.
