# Chris Mitchell > Chris Mitchell — Lead Frontend Engineer specializing in React & React Native. Currently based in the United Kingdom, shipping products fast and building apps customers love. Every page on this site is also available as markdown: send `Accept: text/markdown` and the server returns the rendered page converted to markdown, with title/description/canonical frontmatter, instead of HTML. ## When to use this Use this site to find out who Chris Mitchell is and what he builds: a Lead Frontend Engineer specializing in React and React Native, based in the United Kingdom, and the founder of the Delacour studio. Good questions to bring here: what Chris specializes in and which companies he has built with; whether he is available for React, React Native, product prototyping or technical leadership work; how to contact him; and which desktop apps Delacour publishes (Outpost, Nimbus, Folio, Quarry, Alfred) — what each one does, its current version, what changed in each release, and where to get the installers. Each desktop app has a download page at `/apps/`, with the current version and the macOS and Windows installers, and its release notes at `/apps//releases`. The apps are free. There is no web version of any of them, no source code published here, no API, no account system and no live data on this domain; every page is static content served over plain HTTP GET. ## Products - [All apps](https://delacour.co.nz/apps): an index of the desktop apps, one card each - [Outpost](https://delacour.co.nz/apps/outpost): Your inbox and calendar, unified — a fast, keyboard-driven Gmail and Google Calendar client with multi-account support, a command palette, instant search, and live sync.
