Hello Fabien,
How do you balance between life and your job as a greedy developer, you are developing more than 15 years and almost you wrote all the codes
what is the difference between good PHP developer and a perfect PHP developer?
are you expert as much as your PHP skills in other skills like a database?
what did you do wrong as PHP GURU, in your career?
Regarding the question about being an expert, I'm not sure I'm a PHP "expert". I'm trying to build a PHP framework that solves the kind of problems I'm interested in. I like to learn new things, so along the years, I also learned a lot, from other languages (Python, Ruby, Go, ...) to web related technologies (PostgreSQL, ...).
