Hassan J.

Data Analyst who turns messy data into clear dashboards and decisions you can act on. I help businesses and startups make sense of their data using Excel, SQL, Python, and Power BI. Whether you have scattered spreadsheets, a raw database, or reports nobody trusts, I'll clean it, analyze it, and present it in a way your team can use right away. What I can do for you: • Build interactive Power BI dashboards and KPI reports (DAX, data modeling, Power Query) • Create advanced Excel reports and dashboards (Pivot Tables, Power Query, XLOOKUP/INDEX-MATCH, complex formulas, charts, macros/VBA) • Write and optimize SQL queries for extraction, joins, and reporting • Clean, transform, and analyze data with Python (Pandas, NumPy, Matplotlib/Seaborn) • Automate recurring reports so you stop rebuilding them by hand • Run exploratory data analysis (EDA) to find trends, patterns, and problems • Turn complex numbers into simple summaries for non-technical stakeholders How I work: 1. Understand your business question and goals 2. Audit and clean your data 3. Analyze and build the dashboard or report 4. Deliver clear insights, with revisions until you're happy Why work with me: • Clear communication and fast replies • Deadlines respected, with no surprises • Clean, well-documented work you can maintain or hand off • A Software Engineering background, so I write solid, maintainable code
