About Me
I'm a Data Engineer and Analyst currently based in London, with hands-on experience building ETL pipelines, engineering data infrastructure, and delivering business intelligence that informs real decisions.
My journey spans big data engineering at Tata Consultancy Services, performance-driven marketing analytics, and IT consultancy — giving me a rare breadth across the full data lifecycle.
With an MSc in Big Data Analytics and a foundation in Statistics, I combine academic rigour with practical engineering instincts. I thrive in environments where data has a real impact.
ETL pipelines with Apache Spark, Hadoop, and MySQL. End-to-end data warehousing and quality validation.
Power BI dashboards, DAX modeling, and statistical analysis to surface actionable KPIs.
Data-driven campaigns that increased brand visibility by 40% using Google & Facebook Ads.
UK Full Driving Licence. Available for on-site, hybrid, or remote roles across the UK.

From data infrastructure to visualisation and beyond — here's what I work with.
Academic Projects
Projects that showcase my technical depth in machine learning and statistical analysis.
Real-time detection of human facial emotion and gender using a Convolutional Neural Network (CNN) classifier integrated with OpenCV and Python. Achieved a classification accuracy of 57.2% for facial expressions across multiple emotion classes.
Developed a dynamic R Shiny dashboard with multiple visualisations — charts, a correlation heatmap, and matrix — exploring the relationship between COVID-19 case trends across countries and weather conditions.
Created Power BI dashboards for PwC Switzerland's virtual experience programme, communicating KPIs and analysing HR data to surface root causes of gender imbalance at executive management level.
Cleaned, modelled, and analysed 7 datasets in Excel for a hypothetical social media client at Accenture, revealing content trends to drive strategic decisions. Delivered findings via a PowerPoint presentation.
Education
A blend of statistics and big data that underpins everything I build.
Focus on large-scale data processing, machine learning, and analytics pipelines.
