What I'm looking for

I'm seeking an opportunity to apply my data science, analytics, and full-stack development skills to build useful data-driven solutions and responsive applications that support organizational growth.

I've built practical web platforms including a Women's Voice Portal for anonymous grievance reporting, deployed for 200+ college students, and the Study Circle App, a collaborative learning platform used by 50+ active students. My work includes role-based access, automated quiz scoring, performance tracking, complaint prioritization, and responsive interfaces.

During my Data Science internship at SIIT Technologies, I cleaned 10,000+ row datasets, improved downstream model accuracy by about 12%, trained classification models, and created Power BI dashboards for sales and churn trends. I'm pursuing a B.Sc. in Data Science and enjoy applying Python, PHP, MySQL, and web technologies to build useful, data-driven solutions.
