Full Stack & AI Engineer
about me
I'm a full-stack & AI engineer with over 2 years of experience working across Python, TypeScript and React. I specialize in connecting backend logic to intelligent systems, with UX in mind. I build GenAI agent workflows in LangChain, LangGraph, Google Cloud, Azure, and more. I'm great at designing APIs and building automations.
I'm framework agnostic, with my focus being on writing clear, testable code built for function over form. I'm fascinated by graphs and genetic algorithms, and I love reading fiction and research papers in my free time. I also teach computer science to secondary school students on weekends and make videos about it too.
