Work Experience

Founding GenAI Engineer at Vega IT
April 30, 2025 - July 24, 2025
Led end-to-end development of production-ready Generative AI products combining React frontends, LLM inference, and vector memory systems. Designed LLM agents with tool use, memory, and chain-of-thought reasoning for document Q&A and intelligent assistants. Integrated semantic search (FAISS, pgvector) with LangChain pipelines for RAG-based user experiences. Directed multi-agent architecture, including stateful LLM flows using LangGraph. Drove cross-functional collaboration with designers, product owners, and backend teams.
Senior Machine Learning Engineer at PanonIT LLC
December 1, 2023 - July 24, 2025
Built and optimized Retrieval-Augmented Generation (RAG) pipelines for LLM applications across healthcare, agriculture, and enterprise data analysis. Developed LangGraph-based multi-agent systems and integrated OpenAI GPT APIs with third-party services. Deployed solutions to AWS with a focus on scalability and latency optimization. Contributed to internal tools for ETL processing, embedding management, and pipeline monitoring.
Artificial Intelligence Engineer at Zumoko
March 1, 2021 - July 24, 2025
Delivered real-time computer vision solutions for AR/VR platforms in industries like manufacturing, museums, and healthcare. Fine-tuned CNN-based pose estimation and object recognition models; integrated OpenCV and TensorFlow with Unity and custom engines. Participated in SLAM, visual localization, and edge deployment research. Designed tools for data annotation, preprocessing, and augmentation.
