Work Experience
Teaching Assistant at IIT Madras
June 2024 - May 2025
- Collaborated with professors in various data science/operations research courses by incorporating real-world datasets and case studies.
- Delivered 10+ Hrs of Python/Machine Learning Lab sessions of Multivariate Statistics in class of B-Tech DD (Quant Finance), MS, PhD students
- Developed comprehensive data science scripts & exercises on topics like clustering, regression, PCA, decision tree, etc that improved students performance gradually by 20%
Graduate Engineer Trainee (GET) at Varroc Engineering
August 2021 - July 2022
- Implemented data-driven process optimization using Six Sigma (DMAIC) methodology that reduced changeover time by 77%, saving 33.09 hrs/mo and generating Rs 4.86 lakhs in annual savings.
- Designed and executed 120+ time and work studies, creating interactive data visualizations that identified critical bottlenecks in manufacturing processes.
- Built predictive models to forecast equipment failures, reducing unplanned downtime by 23% and improving overall equipment effectiveness.
- Recognized with SPACE Level Kaizen Competition award for innovative data-driven process improvement solutions.
My Projects
BLINKTO - Predicting Demand of a Food Delivery App [Forecasting]
- Conducted EDA, Data Viz., PACF, ACF, ADF test to infer about stationarity, and converting non-stationary time series using first order differencing.
- Predicted Demand forecast using state-of-the-art ARMA, ARIMA and LSTM model with extensive Hyperparameter tuning that improved model accuracy by 18%, optimizing for epochs, batch size, & lags.
- Demonstrated Proof-of-concept using Streamlit allowing users/stakeholders to get insights in a glance.
