OverviewAs Wayfair technology teams begin their replatforming journeys, more engineers will make decisions for their single purpose database. Choosing the right database technology is one of the most important decisions you can make when building a new microservice. If you realize down the line that you have made the wrong choice, migrating to another database can be a costly and risky procedure. We committed to Google as our cloud platform provider, and they offer multiple robust database options. Learning enough about all of them to make an informed decision can be a steep hill to climb; therefore, we set out to streamline this process, and provide our teams with a guide to help make these decisions.

You’ll be hard-pressed to find a business area that’s garnered more attention over the last 2+ years than the supply chain. Just recently, Wayfair CTO Fiona Tan spoke about the supply chain at the FORTUNE Brainstorm A.I. 2022 event in San Francisco, where the focus was, you guessed it, artificial intelligence (AI). More specifically, how businesses are shifting from dabbling in A.I. to putting it into the hands of every worker.

Testing is the critical part of software development. Unit testing is usually where it starts. That’s because it is quick and easy to get started and builds the safeguard to protect the future code changes to ensure they are inline with the corner cases. It is also much easier to maintain. The biggest advantage of unit tests comes from forcing the developers to write modularized and testable code.

As with many e-commerce companies, recommender systems are widely used at Wayfair to show the most relevant products to customers at every stage of their shopping journey. Machine learning models used in recommender systems typically optimize for metrics related to customer satisfaction: actions such as clicks, conversions and Add-to-Cart. My talk at the 2022 Annual Meeting of the Institute for Operations Research and the Management Sciences (INFORMS) was related to how Wayfair is utilizing inputs from our supply chain to influence the products we showcase to consumers as they search and browse our storefront.

Advertisements are a key aspect of Wayfair’s marketing and growth strategy. Powering each of these ads is a plethora of data - product name, description, price, quantity - all used to maximize RoAS (Return On Advertising Spend) and present the highest quality ads to potential and returning customers. As one might expect, managing this data is no easy task. Different teams handle different subsets of data, and each has its unique platform and way of providing access.

Innovative businesses are always in search of new features and solutions that can transform the customer experience. When a new idea emerges, developers will often work at an accelerated pace, taking calculated shortcuts to prove the value of the concept in as short a time as possible. At this point, the mantra is, “Why exhaust long cycles on something that may ultimately fall short of expectation?”

Some people hate roadmaps. They are a pain to put together, formatting is annoying, your plans will probably change next quarter, and who looks at these things anyway? As Drift CEO David Cancel said of a typical roadmap, “either I’m going to disappoint you by giving you exactly what we thought six months ahead of time was the best solution when it’s not, or by changing course and having lied to you.” While much of what Cancel says is true, because no roadmap is future-proof, I’d encourage any roadmap haters out there to think about it differently.
