Freelancer profile translated to English.
Back to original languageAbout Jonathan
I am a freelance developer with a dual specialization: embedded systems (particularly for audio) and interactivity.
I spent about ten years designing and maintaining all the software for a range of digital musical instruments, from real-time firmware on STM32 to cross-platform desktop applications in C++/JUCE or internal tools in Objective-C/Cocoa.
Interactivity has been a constant throughout my career. I have a background in human-computer interaction and I pay close attention to the actual use of the systems I develop: how they will be used, understood, repurposed, or adopted.
Today, I am looking to collaborate with teams or project leaders who need a solid technical perspective, but also an interlocutor capable of understanding the broader issues: architecture, user experience, production constraints, code scalability.
I work on projects that require structure, clarity, and a certain attention to detail. I can work alone or in a team, on a prototype or on a production tool.
Even in urgent situations, I ensure that the work remains clean and robust.
