Release Early, Release Often



I’m an expert software engineer in the field of Rich Internet Applications. Web technologies are evolving super-fast, and no one can keep up-to-date on all existing frameworks. But with a strong sense of synthesys, a high learning capacity, and a global vision of software developement, it’s possible to find the technologies that best serve customer needs in a long-term, maintanable and evolutive product, while keeping the developement phase quick and efficient. For that reason, even if I do have some specific frameworks I worked with more often or more deeply, I’ll never stick to a given framework if it’s not necessary and if there’s one out there that fits the project better.
