What I'm looking for

I'm looking to apply data analysis and predictive-modeling skills to meaningful datasets, build clear dashboards and reports, and grow through collaborative work with technical and non-technical teams.

I've collected and processed real-world lead-acid battery data at the National Institute of Technology, Tiruchirappalli, identifying degradation trends before model-building.

I built and statistically validated a hybrid CNN and XGBoost predictive model against baseline methods, then documented the methodology and findings for a research team. I also maintain accurate facility-data trackers and reports as an Operations Executive Intern at Smartworks Coworking Spaces.

My projects span federated battery thermal classification, thermal-aware battery management, battery state-of-health prediction with LSTM, and reinforcement-learning optimization for EV battery packs.

I use Python, pandas, NumPy, scikit-learn, PyTorch, XGBoost, MATLAB/Simulink, Excel, and Chart.js to turn datasets into models, dashboards, and accessible technical summaries.
