# Discovery call with Adrian Szczepański

> Discovery Call — 30 min, free A short working conversation about your on-device ML or Python problem: a model that needs to run on Apple Silicon, a pipeline that's too slow, a system that's stuck. What you'll leave with: — A clear framing of the problem (often half the work) — My first read on where the leverage is — A straight answer on whether I can help — and if we fit, a scoped proposal within two business days Come with specifics: what you're building, what hardware it runs on, what "too slow" means in numbers. If we don't fit, I'll say so and point you to someone who does. — Adrian
