I am a Data Analyst & AI Engineer with professional experience in building production ML systems—including real-time anomaly detection using clustering, association rules, and reinforcement learning. I hold a UK BSc in Data Science and MSc in Big Data Analytics.
I translate raw data into business impact: interactive Power BI/Tableau dashboards, predictive ML models (forecasting, churn, risk scoring), and executive reports. I've worked across sales, sentiment, and healthcare analytics, bridging advanced statistical modeling and real-world deployment to answer complex business questions.

FAQ
What data formats do you accept?
Excel, CSV, or direct SQL database connections. If your data lives somewhere else (e.g., Google Sheets, an API), message me first to confirm compatibility.
Which tool will you use — Power BI or Tableau?
Whichever you prefer, or I'll recommend based on your use case (Power BI for Microsoft-ecosystem businesses, Tableau for more advanced visual customization).
How many pages or views can the dashboard have?
1 page on Basic, 3 pages on Standard, 4-5 pages on Premium. Need more? Message me for a custom quote.
Can the dashboard be interactive?
Yes — filters and drill-downs are included from the Standard tier up. Basic includes simple static filters.
Do you include KPIs and insights?
Both — every dashboard is built around the specific business questions you need answered, with relevant KPIs front and center, not just generic charts.
Can you follow my company branding or color scheme?
Yes, on the Standard and Premium tiers. Send your brand colors/logo and I'll match the design.
Will I get the source file after completion?
Yes — the source (.pbix or .twbx) file is included so your team can edit it going forward.
What if I want revisions?
Included per package (1/2/3 rounds respectively) — just tell me what to adjust.
