NepalWhat I'm looking for
I’m a Commercial Data Analyst focused on turning retail and revenue data into actionable insights that directly improve performance. I’ve built and automated KPI reporting to help teams monitor commercial outcomes, forecast demand, and make better decisions.
At H&M Flagship Store, I delivered automated Power BI/Excel dashboards analyzing £8M+ weekly sales and conversion trends. I integrated multi-source data (CRM, POS, loyalty, sales), partnered with product/finance/operations on KPIs and forecasting, standardized reporting processes, and reduced overtime cost by 12% YoY through data-informed workforce planning.
As a Team Leader (Sales & Marketing), I coached a team of 100+ staff and drove +37% YoY sales growth. I monitored CRM and campaign performance to optimize customer engagement and used sales and product analytics to support merchandising and operational decisions.
More recently as a Trainee BI analyst at Maven Analytics, I built data models, pipelines, and dashboards in Power BI and Tableau from scratch, using SQL/Python and API integration to perform ETL and EDA. I also developed KPI trend solutions and applied NLP sentiment analysis to identify patterns in customer feedback and satisfaction.
