    Bio

    I am a freelance software engineer and WordPress consultant living in Germany.

    I am the maintainer of WP-CLI, the command-line interface for WordPress and I work on WordPress Core itself as a contributor and component maintainer.

    I offer higher-level consulting, code reviews and software design coaching, enabling companies to deal with frequent change and ever-growing complexity while optimizing for reduced maintenance effort and lower total cost of ownership.

    Passionate about software architecture and code quality, I never miss an opportunity to share best practices and try to live up to my educational aspirations through public speaking and blogging.

    You can read my thoughts on code & other things at https://www.alainschlesser.com or say hello on Twitter under the handle @schlessera.
