Are you one pancake shy of a full stack? If your web-based internal tools have a distinctly by-engineers-for-engineers aesthetic, and you want to rapidly create more-attractive and intuitive apps, it’s well worth your time to learn ReactJS. That’s what I did while creating a dashboard for viewing current, upcoming and previous releases for the mobile […]
Documentation is a tough sell to software engineers. We want to invent amazing features and write code, and when we finish doing that, we want to do it some more. We don’t want to take the time to sit down and actually describe what we’ve done. But if we don’t, how is anyone else — […]
My product-focused engineering team at Credit Karma works on a wide variety of projects: designing product experiences, building front-end features, spinning up back-end services and analyzing data. We interact with a diverse set of people to get these things done. At one point, we might be asking for help from a platform engineer, and at […]
We use big data at Credit Karma for data science modeling and analytical reporting, which helps us assess the efficacy of our products and services. We process and store data in Google BigQuery at scale, and we do this with data security, data quality, data lineage and data management as our key requirements. These make […]
We’re excited to announce the relaunch of the Credit Karma Engineering Blog. We’re up and running on a new platform, and we’ll be sharing a host of new content from our engineering team […]
Stopping rules are what make most frequentist (a.k.a. classical) statistical tests valid. Unsurprisingly, they tell you when to stop an experiment, and equally unsurprising, they are rules that must be followed in order to get statistically valid experiments from statistical tests that depend on them. However, despite stopping rules being critical to the interpretation of […]
In the era of big data, the choices of data formats are dazzling, and the concept of data format itself can be confusing. Our data platform team found it helpful to breakdown this topic based on the three major stages in the life cycle of data: in-memory representation (logical format), on-the-wire serialization (exchange format), and […]
When I started at Credit Karma, it was my first internship outside of Toronto. As a Computer Science student at the University of Waterloo, I have the opportunity to complete six internships; Credit Karma has been my third. So having done this two times before I had learned one very important thing: what you get […]
Summer started, class was over, and I had begun a 10-week journey with Credit Karma. Intern life was great: there’s free food, a foosball table, the sights and sounds of the city. However, the main point of an internship is to solve a problem, and in order to solve problems, you need to know how […]
As you are conducting your interview, you need to give the interviewee a chance to answer a question well. Here is a high level walk through of how to bring a candidate to the best answer they have. Our philosophy at Credit Karma is to get candidates comfortable. That is how they will be when […]
