03 / The person behind the pixels

Hi, I’m Rémy.
I build. I care.

I’m the founder of Apps Horizon, a mobile engineer with over a decade of experience building consumer apps, from banking and news to social experiences.

I believe good architecture should make a team’s life easier. I bring the same care to the code, the product, and the people building it.

Working with teams across the US, Canada, Europe, and beyond has shaped how I build: stay curious, communicate clearly, and make room for different perspectives.
