The document is a self-introduction of Kent Ohashi, who is proficient in programming languages including Haskell, Clojure, and Python. It details projects related to building REST servers and clients, highlighting features of Haskell's Yesod and Clojure's Duct frameworks. Additionally, it includes links to source code for various versions of the projects and emphasizes type safety and data-driven architectures.
