What I'm looking for

I’m looking for data science and analytics roles in the UK—where I can build dashboards, deliver actionable insights with SQL/Python, and apply forecasting and modeling to support business decisions.

I’m a data analyst and data scientist with a double master’s in data science and mathematics, backed by 6 years of experience turning complex datasets into clear, decision-ready insights. I’m known for handling large data confidently, applying strong logical reasoning, and maintaining a sharp attention to detail.

In my current UK role as a Data Analyst, I analyze complex people-related datasets using SQL, Python, and Excel to deliver insights and reporting for business stakeholders. I also create and maintain Power BI dashboards and KPI reports, including building Python-based dashboards with Plotly and HR analytics dashboards in Power BI to support strategic decision-making.

Previously, I delivered real-time Power BI dashboards (including Black Friday trackers) and improved efficiency by 50%, while forecasting sales using ARIMA and moving averages. I’ve built Python models such as logistic regression and market basket analysis to boost campaign effectiveness, and I’ve supported analytics across customer acquisition, ad performance metrics, and forecasting—plus earlier work that included statistical modeling in R and ETL work for cancer genomics on TCGA data.
