Gamma × Playdate — AI-Powered Investor Pitch & Product Storytelling
Turning evolving startup ideas into clear, investor-ready presentations.
Partnered with Gamma to demonstrate how I use Claude and Gamma to transform evolving product ideas into compelling visual presentations, using my startup, Playdate, as a real-world example.
Playdate is a flexible, multi-stop itinerary planning tool for parents. As the product strategy evolves, I use Claude to refine the narrative and Gamma to translate those ideas into structured, visually engaging slides.
My contributions
• Product positioning and storytelling
• AI-assisted narrative development
• Investor pitch presentation design
• Visual communication and content structuring
• Product demo video creation
Outcome: A sponsored product walkthrough demonstrating how founders can move from changing business ideas to polished, investor-ready presentation materials more efficiently.
Tools: Gamma, Claude

Portfolio website design
I designed and built my own portfolio in Next.js, React, and Tailwind so the site itself shows how I work, not just the case studies inside it.
It is an interactive site with case studies, about, and blog. Visitors can move through shipped product work, including PetCard, where I helped ship a real product using AI as a design collaborator. The goal was a clean, conversion-minded site that feels simple and makes the work easy to understand.
