Applied AI and full-stack engineeringfor teams that need it shipped.
We build AI voice and chat agents, add AI to the product you already have, ship web and iOS apps, and harden codebases you inherited.

What We Build
AI agents, AI features, and the software around them
Built by the engineer who runs a production AI voice product, from the model layer to deploys and on-call.
Selected Work
Shipped and running in production
An AI voice product for law firms, a security overhaul of a medical-imaging platform, and our own apps on the App Store.
How We Work
Fixed-scope sprints or a monthly retainer
Fixed-scope sprint
A defined outcome, scope, and timeline, agreed before work starts. Best for a first build, a voice agent, or a rescue.
Monthly retainer
Ongoing engineering capacity for teams that need a senior builder on call: new features, AI work, and on-call support.
AI-native process
Agentic coding, test-first changes, and human-reviewed pull requests. You get speed without giving up review or ownership of the code.
