I help founders and engineering teams turn stochastic models into deterministic products.
Most engineering teams can throw together a LangChain demo in a weekend. It looks great, but it hallucinates 20% of the time, costs $0.50 per query, and takes 10 seconds to respond.
That's not a product.
Bridging that gap requires more than just prompt engineering. It requires deep knowledge of evaluation, caching, fine-tuning, and robust software architecture.
I don't just write prompts. I build the API, the frontend, and the database schema.
We don't guess if it's better. We measure it -- automated eval pipelines that have driven a 482% lift in engagement.
I help you decide what *not* to build. One vendor off-ramp saved a client $60K/mo.
Flexible engagement models depending on your stage and needs.
