Julien JungUpdated Jan 21, 2026

I was born in Paris, France, and now live in Ho Chi Minh City, Vietnam.

Over the years, I have built and launched several startups and digital products as a solopreneur, managing engineering, design, marketing, and product decisions.

I am passionate about creating tools that help people live more productive and creative lives, and I currently work as an independent developer and designer, building and shipping products entirely on my own.
