Everyone has something worth automating. These three were mine.

  1. Someone in the family gets sick.

    The bills and the lab reports start arriving and nobody has time to file them. A photo into a chat is the whole interface: a vision model reads the provider, the date and every line item out of it, and the dashboard is what the family looks at instead.

  2. Money that needs decisions you have no time to make.

    Two horizons are graded separately, and a bull and a bear take opposite sides of the same position before anything is recommended. The disagreement goes into the report rather than being smoothed out of it.

  3. Help that can act for you, and has to be stoppable.

    It reads the failing job and names the fault. Then "patch it" is refused at the tool layer — not declined by the model, unreachable — because that action was never granted to this profile.

23 skills · 7 systems

Everything on this page runs on the same habit: notes in plain Markdown, linked note to note, in one private vault, with a pipeline that turns whatever it is fed into a knowledge graph. This is that treatment applied to the page itself. Each skill is a node, joined to the systems above that exercise it; the rest were built up across the roles below.

/Experience

7+ years
  • Developed and deployed custom local AI agents automating data reporting, semantic retrieval, and SQL query generation against the asset data model
  • Engineered automated financial data extraction workflows in Power Automate, improving accuracy and eliminating manual report assembly
  • Extended the SQL agent to generate data-quality checks, validated by execution in Snowflake and promoted to the team's approved check set — replacing hand-authored validation SQL
  • Led a team of 7 on standardised data-annotation practices, improving downstream data integrity
  • Streamlined asset documentation and handover workflows, accelerating stakeholder approvals
  • Automated semantic-model database queries and data pipelines
  • Designed and implemented an EACR workflow and compliance framework from scratch under tight project deadlines
  • Validated asset coordinates in QGIS and resolved data extraction discrepancies
  • Standardised data collection with cross-company engineering teams and subcontractors
  • Executed end-to-end verification and validation for the BOND-PRIME staining platform ahead of EU market launch, ensuring IEC/ISO compliance
  • Tracked test execution, defect resolution, and requirement traceability in HP ALM across multiple product iterations
