About the authors
Martin Fjordvald is a 29-year-old Danish entrepreneur who started his company straight
out of high school. Backed by a popular website, he became a jack of all trades having to
deal with the business, programming, and marketing side of his business. The popularity of
his website grew and so did the performance requirements of his code and servers.
He got involved with the community project to document Nginx early on and has written
several blog posts and wiki articles detailing how Nginx works.
Special thanks to the entire Packt team for their patience during the course of writing this
book.

allowed him to discover Nginx. Clement now works as CTO. for a Hong-Kong-based
