Work and projects

Notes on my work, with related code and examples.

Implementation notes without client-specific details.

  1. in production

    retrieval + reasoning · evidence assembly · cite-or-refuse · audit + replay

    Research workflows

    Research workflows I work on using retrieval, extraction, and citation checks. The public reference illustrates part of that approach with synthetic data.

    Local model training

    A tool for reviewing corrections and comparing local model updates before deciding whether to use them.

    My work covers the correction and evaluation workflow.

    The workflow produces candidate lessons, model comparisons, and a review step before promotion. The scorecards describe performance on the evaluated tasks, and previous model versions remain available for rollback.

  3. personal tools

    MCP / hooks · agentic commands · quality gates · automation

    Coding tools

    Tools I use with coding agents, including Ocelin, a local companion for Codex and Claude with session previews, searchable history, and an optional Windows app.

    I develop and maintain tools for my coding workflow.

    Tools I use to follow agent sessions, find previous work, and organise coding tasks with tests and review.
