What I'm looking for

I seek roles applying ML/NLP and data engineering to drive measurable business impact, in collaborative, data-driven teams with opportunities to scale models and influence strategy.

I am a results-driven Senior Data Analyst with over five years of experience building and deploying machine learning models, ETL pipelines, and NLP solutions across finance, marketing, and government sectors. I hold an MSc in Business Analytics and have a strong track record improving business outcomes through predictive modelling and automation.

My work includes developing Bayesian model pipelines that increased trading strategy alpha by 400%, building portfolio-construction frameworks based on Modern Portfolio Theory and clustering, and creating attribution and reporting systems that reduced manpower needs by 80%. I design interactive dashboards and real-time data systems to monitor model performance and support cross-functional teams.

I prioritise model reliability, robustness, and continuous validation while leveraging AWS, PySpark, TensorFlow, PyTorch, and modern data tooling to deliver scalable solutions. I seek opportunities where I can apply advanced analytics and ML to drive measurable business impact and operational efficiency.
