Wayfair’s software engineering history demonstrates a common theme throughout its time: It moves fast and is a core trait of our business. To create and support the right foundations, we need our infrastructure to move faster than our ideas, and this is especially true for our hybrid environment objectives in…
In September, Wayfair hosted React Boston 2018, two full days of augmented reality demos, beautiful and surprising web animations, DOM-related horror stories (with mostly happy endings), component kits, game shows, Forbidden Planet references, and more, all made possible by ReactJS. This year picked up on several of the themes introduced…
As part of the Python Platform Team here at Wayfair, I help support Wayfair’s 100+ Python engineers and data scientists. We’re the go-to team when it comes to better leveraging Python within the Wayfair Tech ecosystem. During some recent project work, we recently investigated a production issue with a Flask…
Early in 2017, in the course of deciding to convert to React as our frontend framework, we realized we needed to render our React components on the server. We adapted Airbnb’s open source Hypernova renderer for our purposes. In particular, we implemented custom module resolution and modified the Hypernova module…
In the Wayfair Network Operations Center (NOC) we wear a lot of hats: Code Deployers, Debuggers, Production Triage, and Incident Coordination, to name a few.

PHP7 is out. This isn’t news. It’s been out since last December, with nine minor revisions since then. What’s new is that it’s serving all of Wayfair’s customer-facing traffic. Performance-wise, PHP7 is the rocket ship people said it would be. We’re nothing but pleased. If you can upgrade, you should do…
On the search and recommendations team at Wayfair, we like to think of ourselves as sophisticated men and women of the world. We have speakers of French, Chinese, Hebrew, German and Persian in the crew. Some of us host couchsurfers at our swanky apartments, and then turn around and couchsurf…
Data Warehousing at Wayfair In 2009 Wayfair’s database infrastructure was based almost entirely on Microsoft SQL Server. Our Business Intelligence team was using a SQL Server data warehouse to prepare a large amount of data for import into Analysis Services (SSAS) each day. We populated our data warehouse using transaction log shipping from production…
We use the Apache SOLR search platform behind the scenes at Wayfair. Sometimes, when vanilla SOLR doesn’t quite do what we want, we improve it for our purposes. When we suspect that others might have the same purposes, and we think that we have solved our problems in a generally…
