Data Scientist & Data Engineer | Python, SQL, Power BI, Machine Learning | Building Production Pipelines & AI Automation Workflows | Ex-Data Intern @ OBLYTECH INDIA | Turning Raw Data into Deployed Models & Insights

About

Most data initiatives fail not because algorithms are lacking, but because the underlying pipelines are fragile and the business metrics are poorly framed. I build end-to-end data systems: transforming raw database tables with SQL and Python, engineering predictive machine learning models, and building automated data workflows that stakeholders can trust. During my internship at OBLYTECH INDIA PRIVATE LIMITED, I experienced real-world data at scale: navigating messy schemas, writing automated Python cleaning scripts, and building self-serve Power BI reporting that reduced manual reporting overhead. Here is how I structure my technical capabilities: • Data Engineering & Ingestion: Python (Pandas, NumPy, OOP scripts), Advanced SQL (Window functions, CTEs, indexing, query optimization), Relational Database Design (PostgreSQL/MySQL), ETL pipeline automation. • Machine Learning & Data Science: Predictive Modeling, Feature Engineering, Scikit-Learn, Supervised Learning (Regression, Classification, Tree Ensembles), Cross-validation, and Model Evaluation (Precision/Recall/F1-score over raw accuracy). • Analytics & Business Intelligence: Power BI (Star Schema dimensional modeling, DAX measures, automated refresh workflows), Exploratory Data Analysis (EDA), Seaborn, Matplotlib. • AI Automation: Automating manual data workflows, API integrations, scheduled ingestion scripts, and LLM-assisted data pipelines. Outside the code editor, you'll find me breaking down open-source machine learning repositories on GitHub and participating in data community discussions. Actively exploring full-time opportunities in Data Science, Data Engineering, and AI Automation. Want to review my code or discuss an open role?
