AI Engineer Alliant Insurance Services

  • Lead developer on a benefit extraction platform that turns uploaded benefit summaries into structured, Excel-ready benefit grids — cutting analyst extraction time from 30–50 minutes per document to about 2.
  • Architected the full system on Snowflake's native stack — React frontend and FastAPI backend in Snowpark Container Services, arq-based job queue, and managed Postgres with Alembic migrations.
  • Designed the extraction pipeline end-to-end: uploads to server-side-encrypted Snowflake stages, AI_PARSE_DOCUMENT with layout mode, and AI_COMPLETE with hand-tuned structured output schemas.
  • Built a custom evaluation system scoring extraction output against analyst-verified benefit grids; tuned schemas to a consistent 85% accuracy.
  • Added an analyst-controlled restyling pass — per-field few-shot examples, toggleable, run as a second pass — plus analyst-defined custom fields with their own extraction prompts.
  • Diagnosed intermittent connection failures to Postgres SNAT port exhaustion under concurrent load; resolved by migrating to Snowflake-managed Postgres.

I build production AI systems end-to-end — pipelines, evaluation, and the interfaces around them. If that sounds like what your team needs, reach out.

I also take on select freelance projects — AI tooling, extraction pipelines, full-stack builds. Ask about it.
