Senior Data Analyst with 7+ years of experience turning complex customer, marketing and operational data into trusted decisions. I combine advanced SQL, Python, business intelligence and commercial judgement to lead analysis from an ambiguous question through to measurable action.
DistinctionLSE Data Analytics Career AcceleratorI am a Senior Data Analyst with 7+ years of experience delivering business intelligence, customer analytics, digital measurement and reporting automation across more than 30 client projects and seven industries. I work beyond the production of reports: I clarify the decision, challenge definitions, assess data quality and build analysis that leaders can trust.
My approach combines deep technical delivery with commercial context. I use SQL and Python to investigate performance, design governed KPI frameworks, develop stakeholder-ready data products and explain what changed, why it matters and what the organisation should do next. My experience covers diagnostic, predictive and prescriptive analytics, customer behaviour, marketing effectiveness, conversion, retention and operational performance.
A senior-level combination of rigorous analysis, modern BI, scalable data foundations and commercial judgement, focused on helping UK organisations make confident decisions.

Python is the analytical foundation, with pandas and NumPy used together for data preparation and numerical analysis. Statistical and machine-learning workflows use scikit-learn and statsmodels, supported by clear validation and reproducible assumptions.
Executive dashboards, scorecards and self-service reporting products designed around governed KPI definitions, intuitive drill-down journeys and the decisions each audience needs to make.
Data preparation, modelling, validation and automation across cloud warehouses and API-connected workflows, with attention to lineage, reusable SQL and dependable metric definitions.
Commercial analysis connects customer behaviour and marketing investment to growth, profitability and retention. Findings are communicated with clear implications, limitations and prioritised action.
Examples of how I structure ambiguous questions, engineer reliable analysis and communicate the result as a practical business decision.
Led the design of a multi-factor digital health framework that converted customer sentiment, service, wait time, value and recency signals into prioritised franchise action.
Combined customer and advertising data to segment audiences and uncover spend, engagement and response patterns.
Analysed national appointment datasets to understand service demand, regional variation, seasonality and missed appointments.
Automated the collection and preparation of digital performance data from multiple APIs for repeatable reporting.

A repeatable route from a complex question to an accountable outcome.
