Hello, I'm
Harmanpreet Singh
Software Engineer - Specialized in Machine Learning & AI
I am a passionate engineer with expertise in software development, machine learning, LLMs, and cloud technologies. Dedicated to delivering exceptional results through innovation, data-driven insights, and creative problem-solving.
About Me
I've always enjoyed building things — from scribbling logic in notebooks to shipping code that powers real products. Somewhere along the way, I got curious about the patterns behind the data. That curiosity led me into machine learning, and eventually into designing systems that don't just run, but learn.
These days, I work at the intersection of software engineering and intelligence. I build backend services, search systems, and ML pipelines — and lately, I've been deep into semantic search and autonomous agents. I'm especially into LLMs, cloud-native workflows, and anything that turns raw data into real insights.
I'm currently based in the NYC metro area, working on projects that blend practical engineering with AI that actually works in production. Outside of work, you'll usually find me hacking on side ideas or chasing good light with my camera. If you're curious or want to collaborate, feel free to reach out.
