About me
I'm a Data Analyst with an MSc in Data Science from Goldsmiths, University of London (Pass with Merit), built on a decade of hands-on work with university digital systems, examination and result platforms, SQL-based data verification and web application development.
My path moved from software and database engineering into analytics: data extraction, cleaning and validation, SQL querying, reporting automation, dashboard design, stakeholder support and operational problem-solving. I work day to day with Python, SQL, Power BI, DAX, Power Query, Excel and Tableau, and hold four Microsoft certifications across Power BI, Fabric, Azure Data Science and Azure Fundamentals.
I care about numbers that hold up to scrutiny — documented lineage, reconciled totals, data quality rules and reporting people can actually trust.
