What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth in data analytics and business intelligence.

I am a dedicated Data Analyst and BI Engineer with over four years of experience in designing, building, and supporting effective business intelligence solutions. My expertise spans the entire BI lifecycle, from data validation and modeling to the development and maintenance of interactive dashboards. I have a proven track record of extracting actionable insights from complex datasets, which has significantly driven operational efficiency and informed strategic decision-making.

Throughout my career, I have developed a sales forecasting model for Walmart products using machine learning and statistical techniques, and I have successfully implemented time-series models to analyze large datasets. My role as an Associate Business Intelligence Engineer involved creating performance dashboards that serve as the single source of truth for departmental data, enhancing reporting processes through data transformation and validation techniques.

I am passionate about leveraging data-driven approaches and integrating Gen AI automation solutions to streamline workflows and enhance decision-making. I continuously seek opportunities to apply my skills in innovative ways, contributing to a culture of data-driven decision-making within organizations.
