Voice AI Product Build
A commercial voice product run as a long hourly engagement rather than a fixed-scope prototype — 247 hours across three months, rated 5.0.
The problem
A commercial voice product needed to work on real calls, not curated demo calls. The client had already learned that a prototype which impresses in a meeting tells you almost nothing about what happens at volume.
What we built
Voice agent development run as a long hourly engagement rather than a fixed-scope prototype: 247 hours from June to August 2025, iterating against real usage the whole way through.
Before
- Demo calls are not real calls
- Failures only appear at volume
- Accents, interruptions, edge cases
After

Voice AIAI AgentOpenAI APIPythonWhy it holds up
The length is the point. A voice product does not fail in the first demo — it fails on the hundredth call, on the accents and the interruptions and the edge cases nobody wrote a test for. Sustained hourly work over months is what lets you find those and fix them. The client left a 5.0 rating: “Cat is a talented Python and AI developer, she has a great attitude, quick learner, and overall fantastic experience!”
