01. about me

I build and ship production systems. Right now I'm running a live CS exam-prep platform serving 10,000+ students, and studying Data Science. I've placed top 1% and top 20% in a few ML competitions — classification, regression, semantic segmentation. End-to-end: PyTorch to sklearn.

06. a few things i built

01 · Heavy Equipment Price Prediction

IIT Madras ML project on Kaggle. Ranked 587 / 2,593 (top 23%), scored on RMSLE. Deep EDA plus engineered features on high-cardinality operational data (usage hours, model year, equipment type) to cut resale-price prediction error.

pandas · scikit-learn · regression
