About Me

About Me

My Journey

I'm an AI Engineer with 7 years of experience building intelligent systems for startups and e-commerce platforms. My work focuses on applying LLMs, automation, and NLP using tools like OpenAI, LangChain, and Pinecone. I'm passionate about building AI assistants, product recommenders, and NLP pipelines that drive measurable business value.

I specialize in front-end development with React and TypeScript, but I'm also proficient with back-end technologies like Node.js, databases and cloud infrastructure like AWS. I believe in writing clean, maintainable code and creating intuitive user experiences.
