Available to hire
I am Jeroen Derks, a developer with a strong focus on security and web platforms. Since 2001 I have been a freelancer, and I have used PHP since 1996 and Laravel since 2017. I’ve seen many different companies from the inside and learned how to solve real issues.
I value high-quality, secure code and enjoy working as part of a team where I can learn from colleagues. I am seeking remote freelance work, ideally with Laravel or security roles, or non-programming roles such as Pre/Post Sales Engineer, Project Manager, Product Owner, Scrum Master, or CTO/Co-Founder.
