Currently, I work at Replit as the VP of Marketing and Design. My background is multi-disciplinary in engineering, design, business, and marketing with nearly 20 years of experience in tech. I synthesize my purpose in a life-time mission of building and investing in tools that revolutionize the internet.
Before Replit, I helped scale companies as the first Head of Design at both Webflow and One Medical for nearly a decade of my life. I started my career as a UI Designer for iOS applications in the early days of the app score, started my own software studio (Xhatch Interactive), and was Director of Mobile Design at Black Pixel.
I'm fortunate to align my purpose with my profession. My focus on building great teams, products, and companies though a few different channels.
Operating
I love the day-to-day work at a company, especially unicorns at the growth stage. I'm commited to work at companies that give people access to building on the internet who ordinarly would not have the opportunity.
Investing
I've had the pleasure in my career to receive great guidance. Investing and advising are my vehicles to pay it forward. I'm an independent angel investor in early stage startups and have written 30 checks.
Writer
I write a weekly publication called Proof of Concept, a newsletter focused on growth, experiementation, and creative exploration.
