Leonid Afanasenko

💼 Web Developer & DevOps Engineer at Synergeticon I specialize in responsive web development, Linux environments, Docker, and surveillance systems. My experience spans computer vision (OpenCV, FFmpeg), video stream processing, and data preparation for neural networks — including large language models (LLMs). I design and assemble IT/video hardware systems, including camera setup and robotic components used in advanced automation solutions. In addition to system integration, I build intelligent workflows in platforms like n8n, enabling API integration, logic-driven automation, and service orchestration — vital for modern process automation. I also develop custom AI agents and fine-tune LLMs, contributing to intelligent system design and data-driven solutions. My work includes building Retrieval-Augmented Generation (RAG) pipelines using tools like LangChain and FAISS, implementing vector databases, and leveraging embeddings to enhance contextual data retrieval and generation capabilities. I work with graph databases like Neo4j and data orchestration tools such as Dagster to manage complex, interlinked data systems efficiently. Additionally, I implement and maintain CI/CD pipelines to ensure fast, reliable, and automated deployment workflows across development and production environments.
