Prajakta Bandgar

BITS Pilani, Goa

Mapping the invisible with code.

An engineering student focused on ML/AI engineering and full-stack product development. I build products where AI has a job to do — turning messy real-world data into clear, usable systems.

My work spans AI finance tools, neuromorphic image processing, biomedical signal prototypes, and LLM evaluation.

About me

I'm Prajakta, an engineering student at BITS Pilani, Goa, interested in ML/AI engineering and product-minded software development.

Most of my work starts with messy data: PDF statements, model responses, biomedical signals, image datasets, or sensor readings. I enjoy turning that ambiguity into something structured — a dashboard, a model, an evaluation pipeline, or a product feature that helps someone make a better decision.

I'm especially interested in AI systems that are useful beyond the demo: tools with clear interfaces, grounded outputs, and a reason to exist.

“I like systems that make hidden patterns visible.”
