My Journey

Designing for the 'Human Heart' and the 'AI Mind'.

I’ve spent my career bridging the gap between Aesthetic Intuition and Engineering Logic. Whether it was curating physical narratives in Paris or architecting 0→1 agentic workflows for a stealth AI startup, my mission remains the same: Turning complex technologies into living interfaces that feel like magic.

Present

Founding Product Designer

Leading 0→1 design for an AI-native cooking agent. I established a code-based workflow using LLMs to reduce engineering cycles by 50%. I don't just hand off pixels; I prototype interaction logic that validates complex AI behaviors instantly.

Sep 2024 - Nov 2024

Product Designer (Mobile AI)

Designed an emotionally intelligent mental wellness companion. By orchestrating generative chat flows and crafting thoughtful micro-interactions, I boosted user satisfaction by 60% and retention by 15%. Proving that AI can be warm, not just smart.

Mar 2024 – Aug 2024

Product Designer (XR/AR)

Delivered an AR onboarding experience for industrial engineers, reducing training time by 30%. Translated complex technical workflows into spatially intuitive journeys using Unity and ShapesXR, prioritizing cognitive load management.

Sep 2023 – Aug 2024

Product Designer

Scaled a civic platform for 11,000+ users by architecting a UI system strictly adhering to WCAG 2.2 AA standards. Simplified complex reporting flows, significantly improving data quality and ensuring zero accessibility debt across cross-functional teams.

Sep 2023 – Aug 2024

Master of HCI+D

Developed expertise in Human-Centered Design and Prototyping within a top-tier HCI program. This period culminated in an ACM UIST 2024 Best Paper Award for pioneering AR research, where I applied behavioral insights to design inclusive, multimodal interfaces for the visually impaired.
