About Jakob

Backend developer working in Ruby and Elixir, with a Bachelor's in Applied Computer Science. I gravitate to gnarly data problems and warm communities — and I'm happiest when the two overlap.

Vizlegal - Smart legal intelligence

Lead backend engineer on the ingestion platform behind Vizlegal — turning messy, multi-jurisdictional court output (5M+ documents across IE / UK / EU / US) into something search-, alert-, and AI-ready. Equal parts engineering and data archaeology; some of these rulings predate the typewriter.

  • Document pipelines that route across multiple OCR and extraction backends, with caching and idempotent re-processing as engines evolve.
  • Distributed workflow orchestration across services written in different languages — coordinating long-running ingestion, enrichment, and indexing.
  • Real-time matching of newly ingested documents against saved searches, for keyword alerts at scale.
  • Citation resolution and search across multi-jurisdictional archives.
  • Migrations of live pipelines onto new orchestration and storage layers without losing documents in flight.
  • AI features — case summarisation, automated court calendars, analytics on judges, firms, and litigation patterns — built on top of the same ingestion substrate.
