Hi! I'm Sébastien.
iOS Engineer crafting products that don’t fall apart under pressure.
Based in Paris, France · Available for selected collaborations
I build iOS applications with careful attention to structure, interaction, and detail, creating products that feel precise, calm, and reliable over time.
I’m a freelance iOS engineer focused on building solid products that age well.
I work across the full lifecycle of an app, from early architecture decisions to long-term stability and performance.
I enjoy refining the details that make an experience feel right: clear navigation, thoughtful motion, and predictable behavior.
My approach balances technical rigor with design sensitivity, turning ideas into iOS products that feel considered, durable, and quietly confident.
