About

Across the last decade, I’ve helped international clients such as Lufthansa, Mitsubishi, WooRank, and NA-KD, launch successful products used by millions worldwide.

My expertise primarily revolves around the JavaScript ecosystem, specializing in Frontend Engineering. Beyond contracting, I find great joy in co-founding startups, channeling abstract concepts into tangible, impactful products for a global audience.

My passion currently gravitates towards the health tech and web3 industries, where I find the technological advancements intriguing and exciting to work with.

Check out my projects below and see how they resonate with you and tell me what you think. If you have an interesting idea and need a co-founder or contractor I'd love to hear from you.

Cloopio

Frontend Engineer

Cloopio.com is a platform for booking curated offsite team-building experiences. The site helps companies plan and manage memorable retreats with ease, handling everything from team preferences to logistical details.

I revamped the site's UX and improved key user flows, focusing on clarity and conversion. I restructured and integrated multiple Typeforms, and set up automated workflows using Make.com. This included connecting form submissions to Google Sheets, enabling admins to quickly access and print new booking data.

The redesign significantly enhanced the onboarding experience for users and simplified internal workflows for the Cloopio team. Administrators could now handle bookings more efficiently, and users had a smoother, more intuitive experience throughout the site.
