Experience
AVP of Product @ fluffbotics
Led product, engineering, and growth with a 10-person team, taking the company from early LLM research through mass-market conversational AI and into hardware.

- Built the AI stack in-house across datasets, fine-tuning, and RAG, and scaled the infrastructure to sustain ~178K POST requests per minute.
- Evolved the product into creator AIs, then pivoted into conversational AI toys with on-device interactive AI.
- Reduced inference costs from roughly $45 to $5 per user per month and filed multiple patents around the underlying technology.
- Exhibited at the Nuremberg and New York Toy Fairs and secured a deal worth roughly $1M.
Staff Product Manager @ CareStack
Owned payments, patient-facing products, international localisation, and strategic integrations across a mature dental SaaS platform.

- Owned the patient portal and improved booking, increasing clients’ self-booked appointments by around 30%.
- Localised the core platform for ANZ and UK markets around differences in health systems, clinical workflows, treatments, payments, and regulation.

- Defined the product specifications, design, technical architecture, and AI strategy, including evaluation workflows, production reliability, and cost optimisation.
- Delivered the V1 in roughly two months with a two-person team, compressing work that would previously have taken around eight months with a five-person team.
- This was my first end-to-end product built primarily with AI and deployed to production, and taught me how to make AI-built systems stable beyond the prototype stage.
