About Lev

👉 levk.io

I mainly use the Node / React stack for the development of business applications.

Knowing how to find the "good enough solution" to a problem is, in my opinion, one of the main qualities a developer should possess.
This involves choosing tools adapted to the task at hand, writing expressive code, and considering scalability and performance.
I favor clean code, TDD/BDD, and more generally software craftsmanship. Small is beautiful !
