Start a project
Let's talk about what you're building.
The best fit is usually a 30-minute call where you describe the problem and I ask annoying questions. There's no pressure — if I'm not the right person, I'll say so and point you somewhere better.
FAQ
Questions I get a lot.
What kinds of projects are you a good fit for?
AI features that actually have to run in production, not just demo well. LLM integration, RAG, evals, agents — usually a single well-scoped feature in a 2-4 week sprint. If you want me to "rewrite your whole product with AI," I'm probably not the right fit.
What if I'm not technical?
Totally fine. The first conversation is usually me asking annoying questions until we both understand what you actually want and what it'll cost. You don't need to know what an embedding is.
How do you work?
Direct. You talk to me, not a project manager — I'm the one writing the code. I prefer fixed-scope sprints over open-ended retainers; keeps both of us honest about what's actually getting built.
