03 / About

Builder, mostly. Endlessly curious about people.

I'm Erwan, "Borombo" online. Ten years building mobile products, from my own indie apps to production work inside startups and big brands. These days I split my time between freelance work and building apps of my own.

How I work

Fail as fast as possible to reach success.

I'd rather ship something rough today and learn from real people than polish something perfect that never leaves my laptop. Most of what I know came from building, breaking things and paying attention.

Let's Get Closer

I'm fascinated by how people connect, and what quietly pulls them apart.

Let's Get Closer is where I explore that out loud: modern dating and relationships through a psychology lens, in short videos and essays.

Off the clock

I shoot photos for fun. Streets, strangers, and the small moments most people walk past.
