Hello, I'm
Amar Kumar
Engineer by training, data scientist by passion. I build intelligent systems that turn raw data into actionable insights — bridging the gap between complex analytics and real-world impact.
About Me
The Story So Far
I've always been the person who asks "why?" one too many times. That curiosity led me from an engineering classroom to the world of data science, where every dataset tells a story waiting to be uncovered.
My engineering background gave me the discipline of structured problem-solving. But it was my first encounter with a messy, real-world dataset that truly lit the spark — the thrill of cleaning noise into clarity, of finding the signal that drives a decision. Since then, I've been building models, wrangling data, and chasing that feeling every single day.
I believe great data science isn't just about algorithms — it's about asking the right questions and communicating answers that people can act on. Whether it's predicting customer behavior or visualizing trends that shift strategy, I'm driven to make data useful.

Beyond the obvious Pandas and NumPy — here are five lesser-known libraries that have saved me hours of work and made my analyses cleaner.
Read MoreMaking Sense of Confusion Matrices
Precision, recall, F1, specificity — it all made zero sense until I reframed it with a real example. Here's the explanation I wish I had when I started.
