What I'm looking for

I’m looking for an opportunity where I can use SQL, Power BI, and data cleaning to build dashboards and reporting that drive actionable decisions—especially in analytics-focused teams like e-commerce—while growing my DAX/KPI reporting and visualization skills.

I’m a Data Analyst skilled in SQL, Power BI, and data visualization, focused on transforming raw datasets into clear, quantified results that support business decision-making.

I’ve delivered e-commerce analytics and reporting through hands-on work like my Zepto E-Commerce SQL Analysis, where I built relational schema for 3,500+ SKUs, cleaned and standardized datasets, and surfaced insights such as a 12% revenue variance across categories to inform a discount strategy.

I’m also Google Data Analytics certified, with a capstone experience covering data cleaning, analysis, visualization, SQL, Power BI, and dashboard reporting, and I continually build my KPI reporting skills in Power BI (DAX). Prior experience as a Language Instructor strengthened my ability to design structured performance tracking and communicate outcomes effectively to stakeholders.
