About Me

I’m an AI Engineer based in Toronto, ON, focused on building intelligent, agentic systems and scalable data-driven applications. I work primarily with Generative AI and large language models, with a strong interest in pushing Agentic AI toward more autonomous, real-world software. My experience spans designing and deploying multi-agent systems and production-grade AI applications using tools like Python, LangChain, and OpenAI. I enjoy working at the intersection of machine learning and web development, translating models and ideas into reliable, user-facing systems.
