Stop consumer payment fraud before the user feels it.

EngineeringSteady — flexible pace

What you'll learn

Real-world fraud modeling, low-latency inference, adversarial evaluation, and the payments-domain basics that most ML courses skip.

Build and evaluate ML and LLM-based fraud detection on simulated consumer payment streams. You'll combine classical features with LLM reasoning over transaction narratives and ship a scoring service behind an API.

Who you'll work with

Zero-to-one product work with the KauPua founder. You'll see every layer — data, model, API, UX impact.

Make consumer payments feel like asking a smart friend.

EngineeringSteady — flexible pace

What you'll learn

Consumer-grade agentic UX, payments plumbing, trust/safety prompting, and how to A/B test a conversational product.

Build a conversational AI that helps consumers decide what to pay, when, and how — routing between cards, BNPL, and balances. You'll design the agent, wire it to mock payment rails, and run user tests.

Who you'll work with

Tiny team, direct founder collaboration, fast shipping cadence.
