FAQ

Quick answers for Data Analyst

Focused answers for this role page. Open only what you need.

What kind of reporting work do you focus on?

I focus on KPI systems, budget reporting, retention views, cohort logic, and reporting routines that help teams decide what to change next.

Which tools do you use for analytics?

My practical stack includes Excel, Power BI, SQL, Python, GA4, GTM, Looker Studio, and source exports from business platforms.

How do you make dashboards useful for business decisions?

I start from the decision, not the chart. A good report should show what changed, why it matters, and which action the team should consider.

Do you automate reporting work?

Yes. I use automation when repeated manual reporting creates delays, errors, or unnecessary dependency on one person.
