About Melody

Over10 years of experiencein software development within product and IT teams, primarily on business applications.
Coming from afullstackbackground, my expertise is now mainly focused on **Java backend**, with a strong emphasis on **code quality**, **readability**, and **maintainability**.

What I do today

I support teams on Java backend development, modernization of existing systems, and architecture improvements, with a pragmatic and operationally efficient approach.

  • Development and evolution of Java backend services / APIs
  • Taking over, refactoring, and making existing applications more reliable
  • Improving code quality and performance
  • Designing simple backend architectures adapted to the context

Experience & Context

I have worked on both from-scratch developments and takeover/refactoring projects, in demanding technical environments.
I have also had the opportunity to lead and support teams on technical topics (architecture choices, best practices, quality), without an imposed management role.

Fullstack & Support

My fullstack background allows me to occasionally intervene on the front end when the scope requires it, to ensure better autonomy and a global product vision.

I can also offer, on a targeted basis, technical support around best practices and craftsmanship (code reviews, quality improvement, method sharing).

Availability

Available for Java backend missions, remote or occasional on-site.
