Karan Singh

Lead AI Engineer

As a Lead AI Engineer with a foundation in Senior Full Stack Development, I specialize in architecting and scaling production-ready AI ecosystems. I bridge the gap between complex machine learning models and robust web applications, ensuring that AI is not just a feature, but a core driver of business value.

My expertise spans the end-to-end development lifecycle: from fine-tuning LLMs and architecting advanced RAG applications to building scalable infrastructures using the MERN stack, Python, and AWS. I am a hands-on leader dedicated to technical excellence, mentoring cross-functional teams, and delivering high-impact solutions that leverage SQL, Firebase, and cutting-edge AI integrations.
