In my 15+ years of experience I've also programmed the occasional helper tool running on Linux servers in programming languages like C, and originally I started my professional career writing cross platform desktop UIs with C++. As an allround developer with focus on mobile and web, and a passion for Javascript related technologies I can't possibly list every tool and library I've ever touched - especially not languages and tools which I haven't used in a long time. But you can expect me to quickly get back into older technologies I haven't used for a while or new libraries that I simply haven't had the time to try yet.
