Is your data telling you the full story?
I'm a Customer Insight & BI Analyst with 2+ years of experience turning messy, scattered data into decisions that actually move businesses forward.
Here's what that looks like in practice: ▶ Improved data accuracy by 20% through structured ETL and data cleaning processes
▶ Helped a business make decisions 15% faster with clearer dashboards and reports
▶ Reduced surgical scheduling inefficiency by 10% through performance analysis
▶ Uncovered customer behaviour patterns and revenue drivers for retail businesses
I work across the full data pipeline, from raw data cleaning in Power Query and SQL, to building interactive Power BI dashboards that executives and operations teams actually use.
My toolkit: Power BI | DAX | SQL (MySQL) | Excel | Power Query
I specialise in: ✦ Customer retention & behavioural segmentation ✦ eCommerce & retail analytics ✦ KPI dashboards & performance reporting ✦ Turning fragmented data into strategic insights
I'm currently open to Data Analyst, Customer Insight, BI, and Reporting Analyst roles particularly in tech and startups.
