The work under the AI.

Most AI projects stall on the data: messy sources, pipelines that break quietly, documents nobody can search. That’s the part we fix.

01

Data pipelines

Ingestion, cleanup and storage for real-world data: email, documents, logs and exports. Built to rerun safely, report what failed, and grow to terabytes without a rewrite.

Python · AWS · DuckDB · Postgres · Terraform
02

Search, review and extraction

Classification, entity extraction and search over large document sets, the same work our founder built for Fortune 500 legal teams at UnitedLex. Hosted models such as Claude, directly or through AWS Bedrock, or open models you run yourself when the data can’t leave.

Claude API · Bedrock · RAG · NER/NLP · Self-hosted
03

Data architecture

The layer underneath: schemas, event flows and analytics that hold up under production load, designed with the people who will maintain them after we hand them over.

PostgreSQL · S3 · Lambda · Streaming · Azure

Software we build and sell.

Native Mac apps for people who work with sensitive files and want them kept on their own computer.
