What I'm looking for

I’m looking for a role where I can build and automate data pipelines, dashboards, and QA systems—using Python, SQL, and ML evaluation to reduce manual effort, improve decision quality, and help teams do more with less.

I’m a data and analytics professional with 7+ years of experience building reporting workflows, analytics tools, and data quality processes across sports tech, AI/ML, and SaaS environments.

I use Python, SQL, and APIs to turn messy business questions into practical insight—automating reporting, improving data quality, and evaluating model outputs to keep decisions grounded in reliable data. I’ve built self-serve dashboards and QA routines that reduce manual effort and improve downstream performance.

Most recently, I owned match-day and seasonal analytics for Premium hospitality at Arsenal Football Club, building Streamlit-based reporting that cut weekly reporting time by 70%. I also migrated manual Excel reporting into Tableau within 2 months, saving 5 hours per week, and supported end-to-end testing for a production hospitality website.

I’ve also delivered rigorous AI data annotation, evaluation, and QA for ML and LLM training pipelines, and built an internal Streamlit QA tool that caught 95% of annotation errors pre-training—reducing model retraining cycles by 30%. Earlier, as an MLOps analyst, I built customer success dashboards and supported bespoke model setup using feedback datasets, taxonomies, and performance metrics like F1.
