PROFILE

Siddarthnachannagari

Madhav Nachan developed a robust analytics and machine learning pipeline for the PranayN23/NFLResourceAnalysis repository, focusing on NFL running back performance from 2018 to 2022. He engineered reproducible data processing tools in Python and Pandas to aggregate and analyze player and team data, then extended the platform with deep learning models using PyTorch and TensorFlow for predictive analytics and visualization. His work included implementing weighted sampling, integrating Time2Vec features into XGBoost ensembles, and producing clear documentation to support reproducibility. The depth of his contributions enabled reliable, auditable analytics and improved model accuracy, supporting data-driven decision-making for player valuation and strategy.

Nov 1, 2024

November 2024 — NFLResourceAnalysis: Delivered end-to-end, ML-powered prediction and visualization capabilities for NFL running backs and team-level correlations. The work supports data-driven decision-making for player valuation and strategic insights for teams. Key deliverables include R^2-based performance metrics, RNN/MLP visualizations, and robust graphs with reproducible notebooks. Resolved critical RNN graph KeyError and produced barplots comparing predicted vs actual outcomes (PFF, Net EPA). The initiatives strengthened data reliability, analytics speed, and stakeholder confidence in model-driven recommendations.

October 2024: Delivered foundational data engineering work for NFL running back performance analysis in PranayN23/NFLResourceAnalysis. Implemented data processing tooling and datasets for 2018–2022, enabling consistent, auditable analytics and trend assessment. Key deliverables include rb_combine.py for weighted averages and YoY changes, rb_combined_df.py to merge raw CSVs into a single DataFrame, and additional CSVs aggregating data by player and by team for the same period. Four commits completed to create and aggregate the dataset.
