Back to original languageAbout Sandra
Senior Product Manager specialized in AI & deeptech | 9 years of experience | From idea to product, from prototype to millions of users
I build ambitious tech products in environments where everything is yet to be invented.
My playground: Conversational AI, neural interfaces, IoT, medical devices. I work across the entire product cycle — discovery (user interviews, benchmark, PMF) and delivery (roadmap, specs, sprints) — coordinating multidisciplinary and international teams. I use AI daily to gain efficiency: rapid prototyping, design iterations, automation, analysis.
What I've done:
- Led an AI solution (chatbot/voicebot) handling 10,000 calls/month with +90% accuracy — OpenAI, Azure, ElevenLabs
- Designed the CES 2024 & 2025 demos for a neurotech startup — awarded "Best of CES" by Android Authority
- Managed the Netatmo Weather Station (400K+ users), from HomeKit integration to technical migration
- Structured an internal product deployed to 40,000 users in 10 countries, overseeing a team and managing quality
- Currently: discovery and UI/UX redesign of an AI assistant for dentists (medical device, early stage)
Profile: dual degree in engineering (ECE Paris) & business (Audencia), with exchanges at UC Berkeley and Heriot-Watt. I speak tech with devs and business with stakeholders.
I enjoy complex products, passionate teams, and projects with real impact.
Available for freelance missions in Product Management, product strategy, or 0-to-1 scoping.

Experience
- CadSmileSenior Product Manager (freelance)MEDICALNovember 2025 - Today (7 months)Paris, FranceSenior Product Manager freelance (part-time) at CadSmile, a startup developing an AI assistant for dentists.Arrived at the prototype stage, my mission is divided into two parts:
- Product Discovery: user interviews (dentists), competitive benchmarking, analysis of the existing prototype, and recommendations for improvement to guide product strategy.
- UI/UX Redesign: following my feedback, a complete redesign of the interface to achieve a functional MVP with better user understanding. I designed all mockups in Figma (Shadcn library, atomic approach, mini design system), using AI tools (notably Claude) for rapid iteration.
The product: an app that saves practitioners time daily — voice notes for consultation documentation, AI chat with dictation, X-ray analysis, smile simulation, generation of 3D objects to simplify communication with dental technicians...I collaborate with the 3 co-founders (the CEO from finance and 2 dentists who originated the project), 2 lead developers, and a CMO. As the application is intended to become a medical device, we are also working with specialized clinics and experts on certification.Next step: user testing and beta launch. - FoundeverSenior Product Manager AI (freelance)SOFTWARE PUBLISHINGJanuary 2024 - October 2025 (1 year and 9 months)Paris, FranceAI Product Manager on a conversational bot solution (voicebot) aimed at improving customer satisfaction and productivity for Foundever's customer relations centers.Responsible for the product roadmap from A to Z, I defined priority use cases, conducted user/client interviews, coordinated development teams (front, back/ML), designed, and monitored KPIs with Power BI.What we accomplished together:• 4 pilots launched with major international clients (automotive, retail, services)• +90% accuracy in generated responses• 10,000 calls processed per monthStack: OpenAI (LLM), Azure (STT), ElevenLabs (TTS)A stimulating 0-to-1 project, at the heart of conversational AI challenges.
