I turn raw data into business insight through SQL-driven retail analysis and market-data visualization projects.

For a Walmart sales analytics project, I analyzed multi-store sales data, identified underperforming stores and seasonal demand patterns, and translated findings into concrete recommendations. I used MySQL, Python, Pandas, and Excel to build optimized queries, summary tables, and visual reports for non-technical audiences.

I also built a real-time market data and trading platform with React, Node.js, Express.js, and MongoDB, covering price watchlists, order flow, portfolio performance, charting, and P&L tracking. The project modeled order and portfolio data and exposed it through REST APIs for downstream analysis.

Alongside analytics work, I led backend development for a Teacher-Student Repository capstone and shipped a JavaScript background-removal tool during a remote internship at CodeClause. I enjoy independently delivering structured, data-first solutions to open-ended business questions.
