Healthcare, energy, fintech and education. New platforms, inherited platforms, and a few that needed careful rescue before anyone could move forward.
Promoted to Acting Head of Data while leading a full rebuild of PEP Health's AWS data platform. The work has been part architecture, part team development, part helping the business understand what the data platform should actually make possible. Designed a replacement architecture cutting infrastructure costs by 75%, while putting IaC, CI/CD, testing and documentation standards around the work.
Hired to take over a contractor-built system the business could not confidently maintain. Designed the AWS ingestion framework and Snowflake warehouse from the ground up, then hired and onboarded engineers so the platform had an internal team around it rather than another dependency.
Worked inside an established AWS/DBT environment that had grown faster than its architecture. Re-orchestrated the codebase to reduce cost and failure risk, delivering roughly $50k in annual savings. Mentored engineers and led practical AI fundamentals training across IT.
Enterprise platform modernisation in a large legacy environment, with all the careful sequencing and stakeholder work that tends to come with that.
Built a greenfield multi-tenant BI platform, consolidating 300+ client databases into a unified Redshift warehouse with QuickSight analytics. Reduced cost by 70% while making the estate easier to reason about.
My first data role, and the place I taught myself Python, SQL, ML fundamentals and data warehousing by needing them badly enough.
