What I'm looking for

I'm looking for a data-focused role where I can use SQL, Python, predictive modeling, and dashboards to turn business requirements into reliable, actionable insights.

At Cognizant, I write and optimize SQL queries across 50+ production banking backend services, extracting, cleaning, and validating data for accurate reporting.

I work with business analysts, developers, and QA teams to translate requirements into functional data outcomes, diagnose defects, and document data flows through Swagger. I also built secured REST APIs and responsive applications during my Java Full Stack Developer internship.

I've built Python predictive models using Pandas and NumPy, applying feature engineering, cross-validation, and hyperparameter tuning to improve model accuracy by 15%.

My IEEE-published financial insights platform analyzes income, expense, and user-behavior data to produce AI-driven forecasts, personalized recommendations, and Angular dashboard visualizations; it improved forecasting accuracy by 20%.
