Consulting

Expert data help, personally delivered.

When your business needs more than a report — custom dashboards, SQL analysis, BI strategy, and hands-on data training from Shahin Khan.

Who I am

Data analyst & business strategist.

I'm Shahin Khan — a data analyst and business development manager based in Spain. I built Tenor Analytics because I saw too many SMEs drowning in spreadsheets with no way to make sense of their numbers. I combine technical depth (Python, SQL, Power BI, DAX) with real business context to deliver insights that actually change decisions.
