Mike McCandless

 
Michael has been building search engines for 25 years now, initially as co-founder of iPhrase Technologies in the Boston, MA, USA area, and then (since 2007) focusing on the open source Apache Lucene Java search engine, which distributed search engines like Apache Solr, OpenSearch and Elasticsearch build upon. Lucene now powers 100% of Amazon’s e-commerce high-scale search engine after Michael joined in 2017 to help migrate from an in-house C++ engine to Lucene. Michael wrote the 2nd edition of the Lucene in Action book, also writes occasional blog posts at blog.mikemccandless.com, and stays active on the Lucene mailing lists responding to new users, fixing bugs, adding new Lucene features, and gently engaging in the occasional flame war. Beyond search, Michael loves tinkering with smart home gadgets scripted with Python, as well as fun maker space tools like 3D printers, laser cutters and CNC machines. His latest 3D printer is a 5-head Prusa XL which prints gorgeous multi-color prints with little waste. Michael has a Ph.D. (1998) from the Massachusetts Institute of Technology in Computer Science, and lives in Lexington, MA, USA.
