About Me

I'm a software engineer with a passion for building AI-powered solutions and scalable systems. Currently working at SentientGeeks, I specialize in Generative AI, Computer Vision, and backend development.

My technical expertise spans from developing RAG chatbots using LangChain and OpenAI API to building computer vision solutions with YOLO models for document processing. I believe in writing clean, maintainable code that solves real-world problems efficiently.

When I'm not engineering AI solutions, you can find me exploring new technologies, optimizing system performance, or building production-ready applications.
