Hi, I'm Anna

Junior Data Analyst | Reporting & MI Analyst | Power BI, SQL, Excel | Business-focused Analytics & Decision Support

About Me

I’m a Junior Business / Data Analyst with a background in education, psychology, and financial services.

Over the years, I’ve worked closely with clients and stakeholders, often in fully remote settings. This has helped me understand not just data, but how people use information to make decisions.

I focus on turning data into clear, actionable insights that support real business needs - particularly in areas such as performance tracking, revenue analysis, and operational efficiency.

I work with Power BI, SQL, and Excel to build reporting solutions, analyse KPIs, and identify patterns such as revenue loss, cancellations, and demand fluctuations.

I’m comfortable working independently in remote environments and collaborating with distributed teams. I’m looking for a junior Business Analyst or Data Analyst role where I can contribute from day one while continuing to grow professionally.
