What I'm looking for

I’m looking for global remote opportunities where I can build SQL-driven analytics and machine-learning solutions, optimize large-scale queries, and translate model results into clear business recommendations for stakeholders.

I’m a Data Scientist with 1.5+ years of experience (internship plus full-time) at Infogain, delivering machine learning and analytics solutions on large-scale datasets. I’m strong in SQL (Hive, Presto) and Python, and I focus on feature engineering and rigorous model evaluation to drive measurable gains.

In my role, I analyzed multi-million-row datasets, built classification and segmentation models (Logistic Regression, Random Forest, Gradient-based models), and improved key metrics by 8–12% over baseline. I also optimized complex SQL queries to reduce execution time by 20–30% and worked with cross-functional teams to translate findings into actionable business recommendations.
