Passionate Backend Developer
Hello! I'm Killian Jeuffroy, a 3rd-year student in BUT Multimedia and Internet Careers (MMI) at IUT de Blois.
As a freelance web developer, I design performant and optimized websites, tailored to the needs of businesses and entrepreneurs seeking an effective online presence. From creating showcase sites to more advanced solutions, I ensure careful, secure, and scalable development.
Passionate about backend development, I go beyond simple sites by creating solid architectures, optimized databases, and performant APIs. I also support companies with more technical needs by building custom solutions capable of handling large data volumes and complex infrastructures.
