How I partner

01

Embed with your product team

Join an in-house team to lead market and competitor research, set product strategy, and prototype the next state in Figma and as a working interactive build via vibe coding.

02

Ship the first version with founders

Work with early-stage founders to pin down the real need, prototype the core flows, and ship a v1 that holds up in front of real users.

03

Map what comes next

Run strategic user research with your stakeholders, set a 5 to 10 year vision, and prototype how AI could reshape the product before you commit.

04

Upskill your team on AI

Partner with executives and product teams in mid-size and enterprise companies on a clear AI playbook: where designers should lean on it, where to hold back, and how PMs can ship their own prototypes.

Selected case studies

Foodhack

Foodhack ran a FoodTech media brand and an engaged investor community. I designed the investment platform that turned their manual, intro-by-intro dealmaking into a product that scaled, shipped fast, and closed real deals.

Hafnova

A two-week sprint redesigning Hafnova’s DoHzel mobile app: turning a fragile manual DNS activation into a guided journey and making a technical security product simple for a non-technical Swiss audience.

Digital Key

A two-week design sprint reframing car ownership around shared mobility — a mobile prototype letting an owner issue a secure, time-bound digital key to share their vehicle on demand.
