About Julian

I have been a Full-stack developer for a little over 5 years, with a background split between mobile and backend. I enjoy building an application as much as thinking about how it will be used or the needs it meets.

I've had the opportunity to work in very different contexts: high-growth startups, projects created from scratch, and products already used by thousands of users. In each case, what I appreciate most is being able to participate in upstream discussions, understand the stakes, propose ideas, and build the right solutions with the team.

I am a curious person and I like to step out of my comfort zone. Discovering a new field, taking over an existing project, or solving a complex problem is what motivates me daily.

Today, I am mainly looking for projects where I can have a real impact, work closely with product teams, and support a project well beyond simple technical implementation.
