Biography

My professional passion lies in bridging the gap between cutting-edge Deep Learning and robust, production-grade systems. Currently, I am focused on deploying autonomous LLM agents using frameworks like LangGraph. Additionally, I am working on standardizing communication via protocols like MCP. I thrive on tackling complex orchestration challenges and transforming theoretical models into reliable, high-performing decision-making platforms that drive real-world efficiency. Beyond production systems, I enjoy researching diverse machine learning paradigms, including Federated Learning, Reinforcement Learning, and beyond.

My research focuses on applying machine learning and AI to solve complex problems in 6G networks and smart systems, with emphasis on deep learning for network optimization and energy efficiency.
