What I'm looking for

I'm seeking an entry-level Data Analyst or Data Entry role where I can use my analytical and organizational skills to support data-driven decision-making.

At Decodelabs, I cleaned and prepared a 1,200-row e-commerce and sales dataset using Python, SQL, and Microsoft Excel. I resolved missing values, duplicates, invalid formats, negative values, and calculation inconsistencies to prepare the data for analysis.

In my Sales Data Analysis project, I documented data-cleaning procedures and developed business questions using Excel, SQL, and Power BI. I also built an interactive Power BI sales dashboard with revenue, profit, cost, and customer KPIs, drawing on my experience with data validation and analysis.
