I work with business and domain stakeholders to translate real problems into clear AI and machine learning objectives, then deliver end to end solutions from data preparation and feature engineering to model deployment and monitoring. I apply practical analytics and modeling workflows to build scalable, business aligned use cases and communicate results in a way that supports decision making. I also bring experience from my internships, where I performed targeted web scraping to consolidate business related data, built a retrieval augmented generation chatbot that combined internal data with real time web search, developed Power BI dashboards using Snowflake data to visualize operational insights, and applied topic modeling and sentiment analysis on customer feedback to surface key themes and trends.

I create high-quality mathematics learning materials for students, including lesson notes, worksheets, assessments, and detailed step-by-step solutions. I write clear questions across different difficulty levels, design structured activities, and produce accurate explanations that are easy to follow. I also proofread and refine existing content for correctness, clarity, and consistency, and format outputs cleanly in Word or Google Docs with tables, figures, and polished layouts.
