👨‍💻 About Me

I am an aspiring Data Analyst with a strong foundation in Python, SQL, statistics, data visualization, Power BI, and machine learning.

I enjoy transforming raw data into clean datasets, meaningful visualizations, analytical insights, and data-driven recommendations.

My core workflow is:

Business Problem → Data Extraction → Data Cleaning → EDA → Statistical Analysis → Visualization → Insights → Decision Support

I also have hands-on experience developing Django and MySQL-based applications, giving me practical exposure to relational databases, structured data, backend systems, and data-driven applications.

🎓 Currently pursuing a Post-Graduate Program in Data Science, Analytics & GenAI at Imarticus Learning.

📍 Chennai, India

🚀 Featured Projects

01. 🏏 IPL Player Performance Analytics V2

Python · Django · MySQL · Scikit-Learn · TensorFlow/Keras · Machine Learning · Deep Learning

An integrated cricket analytics and player-performance prediction platform for exploring historical IPL data, analyzing player performance, comparing players, and generating batting and bowling estimates.

Key capabilities

  • Historical player profiles, search, and comparison
  • Match exploration and match details
  • Batting analytics, bowling analytics, and exploratory data analysis
  • Separate ML and DL inference workflows
  • Model comparison and prediction pages in a Django application

Machine learning artifacts

  • Batting production inference uses saved Joblib artifacts.
  • Bowling production inference uses a saved wickets model.
  • The exact algorithm and feature definitions should be taken from the training code, not inferred from artifact filenames.

Deep learning targets

Batting targets Bowling targets
Balls faced Economy rate
Dismissals Legal balls
Fours Runs conceded
Runs scored Wickets
Sixes
Strike rate

Ten saved TensorFlow/Keras target models are organized through a model registry, with preprocessing/scaling artifacts and inverse transformation during inference.

Evaluation concepts: MAE, RMSE, and R². Successful inference confirms that the workflow runs; it does not by itself establish predictive accuracy or generalization. Predictions are estimates, not guaranteed match outcomes.

My Principle

Good analytics starts with a good business question and reliable data.

I focus on understanding:

  • What problem are we solving?
  • What data is available?
  • Is the data reliable?
  • What patterns and anomalies exist?
  • Which analytical method is appropriate?
  • What does the result mean?
  • How can the insight support a decision?
