What I'm looking for

I’m looking for a data-focused role where I can clean data, build interactive Power BI dashboards, and turn findings into executive-ready reports that support better decisions through strong data integrity.

I’m a data analyst with a B.Tech in Physiology and hands-on experience in data cleaning, exploratory analysis, dashboard development, and business reporting. I’m driven by turning complex datasets into structured, evidence-backed insights that support real decisions.

At Decodelabs, I cleaned and prepared a 1,200-row sales dataset in Excel and Python, resolving missing values, duplicate records, and formatting inconsistencies. I conducted EDA to detect outliers using the IQR method and uncovered a critical fulfillment gap—only 19.2% of orders were delivered successfully—and translated findings into a stakeholder-ready report.

I also built an interactive Power BI dashboard with KPI cards, slicers, and cross-page filtering, tracking $1.26M in total revenue across 7 product categories. In the same work, I identified Instagram as the top acquisition channel with 259 referrals and isolated June as the peak revenue month, linking performance spikes to delivery reliability.

Beyond sales analytics, my HR analytics capstone used a 1,470-row dataset to answer 15 structured questions and produced a 3-page Power BI dashboard with DAX measures and executive-ready reporting. I combined that with clinical data research experience where I achieved 100% accuracy and completeness, and I bring that same data integrity mindset to every project.
