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…
Uplift models seek to predict the incremental value attained in response to a treatment. For example, if we want to know the value of showing an advertisement to someone, typical response models will only tell us that a person is likely to purchase after being given an advertisement, though…
It’s been seven months since Dan Uhl reflected on our conversion to React and Redux at Wayfair. The article was written right after the Product Detail Page (or PDP – you might know it as the page you see when you’re ready to purchase a product here at Wayfair) was…
I have just hit the “publish” button on Wayfair’s Tech Radar. This is a manifestation of our commitment to transparently share how we think about the technologies we use to build our systems and applications. We are publicly sharing the exact same version externally that we use to guide internal…
Accurate performance monitoring is crucial for Wayfair’s Storefront Engineering team. Each day we deploy hundreds of code changes to the web application for our customer-facing websites, and each change has the potential to impact performance for better or worse. For this reason, we carefully monitor KPIs such as page load…
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…
Wayfair Engineering is excited to host and organize the first react.js conference in New England on September 23-24, 2017 here at our headquarters in Boston’s Back Bay. Over the last year we’ve partnered with ReactJS Boston, the local react user group, to sponsor and host react meetup events nearly every…
A few years ago, after reading this blog post by Jeff Atwood, we started handing out rubber ducks to new hires in Wayfair Engineering, to encourage self-reliance and good questions in mentoring situations. We have accumulated a lot of ducks over the years throughout the department, but our Search Technologies…
That’s a heat map of 3 months of Wayfair North American orders, exported via Logstash from our relational orders database into Elasticsearch, and visualized with Kibana 4. For some time now, ELK, or Elasticsearch / Logstash / Kibana, has been our opensource platform for text-based log messages, complemented by Graphite…
