Finance, data, and automation — for teams that want clarity.
I help businesses modernise their finance operations — building the reporting systems, models, and automations that turn raw data into decisions.
I'm currently FP&A Lead at Cambridge Spark. On the side, I build tools that make finance easier to run, like CardCode, dplan, and Ledger, and I advise companies on finance ops, analytics, and automation.
