Featured Projects
libft
Systems library
Custom C standard library reimplementing essential libc functions from scratch — the foundation every 42 project builds on.

Sorts a stack of integers using two stacks and a minimal set of operations — an exercise in algorithm design and complexity.
ABOUT ME
Who I Am
Learning in public at 42 Barcelona. I work close to the metal in C and build for the web with JavaScript and React.
Continuously learning — every project is a chance to level up.
Deep work over busywork. Ship things that actually matter.
Details make the product. Quality in every line, every interaction.
