I'm a Data Product Manager based in London. I work around data products, governance, analytics, AI and data engineering. I also run ReadyRoll, a live scheduling app for small groups. I use this GitHub for my own projects and experiments. Some are learning projects, some are useful tools, and some are me working through an idea properly enough that someone else could inspect, run, or build on it.
At the moment I'm building a small set of local-first data agents.
The idea is simple: not every data task should be thrown straight at an LLM. Some parts should be deterministic, testable, and cheap. The agent layer should orchestrate those checks, explain what happened, and produce useful outputs.
- ReadyRoll
- A scheduling app for board game groups and other small groups.
- It helps groups find the best day to meet without messy chat threads or one-off polls.

- A local Python CLI agent for inspecting CSV/XLSX files, running deterministic data quality checks, and producing traceable reports.
