I'm Bill Kernan, a senior software engineer. I build AI document pipelines, backend APIs, and cloud infrastructure, and I set up the review and release process that keeps them dependable.
Pipelines that read documents with large language models, compare the results to your systems of record, and flag what doesn't match. Built with prompt tests and evaluation gates so quality is measured before each release.

Clean GraphQL and REST APIs, data models, and integrations with third-party platforms whose formats and rules differ from each other.
Python · Django · GraphQL · PostgreSQL
Infrastructure defined in code, automated pipelines, protected branches, staged environments, and releases you can undo in minutes.
AWS · Terraform · GitHub Actions · Docker
Apps built quickly with AI assistants need a path from a laptop to real use: a shared repository, code review, testing, and written sign-off. I set that up and train the people building.

I have nine years of professional engineering experience, building full-stack web applications and, more recently, production AI systems. I'm comfortable owning a domain from the data model to the API to the infrastructure it runs on.
Before software, I taught eighth-grade algebra. It left me with a habit I still use on every project: explain the problem plainly, one step at a time, so the people relying on the work understand it.
