ENGINEERING EXPERIENCE

Lead AI & Systems Engineer — R&D Lab & Production AI Projects 2021 – Present
Architected and deployed an autonomous local RAG & Agentic System (hopeok.com.ua) utilizing Python,
LangChain/LangGraph, and vector databases for dynamic document analysis.
Engineered autonomous agent tool-calling capabilities allowing LLM agents to interface with external APIs, execute
Python scripts, and process structured JSON datasets.
Integrated multi-agent collaboration patterns (supervisor and worker agent setups) to break down complex tasks into
executable sub-steps.
Optimized vector retrieval pipelines using hybrid keyword + semantic embeddings, decreasing retrieval latency by
40% while preserving context accuracy.
Designed REST APIs and modular wrapper libraries to seamlessly integrate AI components into existing software
systems and third-party frameworks.

Software Engineer (Python & Systems Integration) — R&D Projects 2018 – 2021
Developed modular Python microservices for automated data ingestion, API integration, and background task
execution.
Implemented async data connectors, memory management protocols, and comprehensive unit/integration testing
suites.

PROOF OF WORK & PRACTICAL IMPLEMENTATION

Live Production Agentic System: Designed and maintains hopeok.com.ua — a fully operational autonomous RAG
system proving real-world experience with tool integration, API design, vector databases, and stateful agent
execution in Python.

EDUCATION & CREDENTIALS
Specialist Degree in Computer Engineering Ukraine
Languages: Ukrainian (Native), English (Upper-Intermediate — technical design, API specifications, and
international remote collaboration).
