What I do

I design, build and maintain – from start to finish, by the same person.

  • Custom software

    Bespoke applications, integrations and automation for when an off-the-shelf product is not enough.

  • AI solutions

    Language models as part of a real workflow: analysis, classification and content production with quality control.

  • WordPress and maintenance

    Custom plugins, security, caching and automated maintenance without a jungle of plugins.

AI-assisted media criticism

An AI-assisted media criticism site that compares how several media outlets report the same story every day – and shows what was left untold, what the information is based on and what later turned out to be true.

Designed, built and maintained by me: a custom plugin of about 108,000 lines, five AI services for comparison and verification, fact-checking and correction tracking. Every release passes automated tests and is signed, and an AI “doctor” monitors and fixes the site every hour.
