Builder, mostly. Endlessly curious about people.
I'm Erwan, "Borombo" online. I've always needed to make things, and building apps turned out to be what I'm good at. The questions I can't stop chasing are all about people: how we connect, why we drift, what makes us feel close. Everything I build circles that, from Jagi to Let's Get Closer to the small apps on the shelf. Ten years in, it finally feels like one thing.

Mobile Engineering
Native iOS and cross-platform apps that feel fast and hold up over time.
Product & Design
Shaping the idea, the flows and the details, so the whole thing feels considered instead of thrown together.
AI Integration
Putting AI into products where it actually helps, not just to tick a box.
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.
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.
I shoot photos for fun. Streets, strangers, and the small moments most people walk past.
