Description

MOI – Product Expert (and fullstack: CPO, PM, UX, UI)

I really love products and product creation.

So after several years in product leadership (2x CPO in scale-ups), I decided 3 years ago to focus entirely on AI, learning (a bit of coding) then creating AI products and using AI to do so.

-> My team: Cursor, Opus, and me.

AI & ME – 2 AI products created (solo and full-time, 2+ years)

I have created two relatively complex and purely AI products. The last one is in production.

The JungStudy.com – Conversational & voice-only AI on the character of Carl Jung. Beta in production since April 2026
GB Concierge – Ambient web AI agent. Complex POC.

AI SKILLS – Agents & LLM

Agents, Web AI Agents, LLM Finetuning, Voice AI, System Prompt Engineering, Context Engineering, AI Memory and RAG, AI Coding.

PROFILE FIT vs YOUR NEED – If you need product strategy, builder, UX/UI, and advanced AI

I am the best profile for you if you need a product expert combining product strategy and product building. With proven product taste and UX/UI skills. Also very comfortable delivering a product from 0 to 1 solo or helping an existing team. And AI expertise that is not theoretical, but a true AI builder.

The Jung Study is a voice-only Conversational AI App

An immersive conversational AI app centered on Carl Jung, inviting users into a contemplative space that feels like sitting in his study—where inner dialogue unfolds through warm, reflective conversation with a wise, grandfatherly presence.

• Development – Built (solo) the production-ready version using Cursor and Opus 4.6
• Finetuning – Finetuned Gemini 2.5 Flash with 200K tokens of Carl Jung material by creating 200 synthetic conversations distilling the Carl Jung knowledge and the expected agent behavior
• System Prompt Engineering – Aggressively iterated in order to find the optimal balance of on-character LLM behavioral impact while not hurting too much the LLM inherent intelligence, natural behavior, and latency
• AI Memory – Advanced Mem0 setup to provide continuity across sessions, while not hurting latency

Beta version in production since April 2026.

GB Concierge is a Consumer Web Ambient AI Agent

Value Pro – Fully abstracting the need for web users to create and manage user accounts on their various websites & apps of interest.

The Magic – As an ambient web AI agent, GB Concierge would act as a proxy for the user to autonomously (i.e. behind-the-scene) create an anonymous user account on each of the various websites & apps of interest for the user. Thus, fully abstracting the whole signup and signin layer across the web.

• Antler Berlin Incubator, Fall 2024 cohort
• Built (solo) a POC using Cursor and Gemini 2.5 mostly
• Iterated aggressively with smart product and technical hacks.

☛ Concluded that this solution can't be taken to production because antibot systems (e.g. Cloudflare) are still too unfriendly to AI Agents.
