About Me
Driven by clean code and robust systems
I am a Senior Data Engineer at THG PLC, specializing in architecting distributed data platforms, designing resilient ETL/ELT pipelines, and building scalable cloud analytics solutions.
My journey began in fraud analysis, where dissecting high-volume transactional patterns and mitigation data sparked my passion for data engineering. Today, I focus on turning complex, petabyte-scale data streams into reliable, high-performance foundations that power critical business decisions.
Distributed Pipelines & ETL
Orchestrating high-throughput, fault-tolerant ingestion pipelines with data quality guarantees.
Cloud Data Architecture
Modeling modern data warehouses, lakehouses, and analytics platforms optimized for query performance.
Transactional & Fraud Insights
Deep domain expertise in fraud analytics, risk detection systems, and e-commerce event streams.
