About DEV team

The development team is an irreplaceable part of our business at Quantlane. Our trading platform allows traders to interact with stock exchanges on three continents in real time. Under the hood, we set up data centers across the globe and develop applications that transfer and record high volume, low-latency data. Because our code handles money in real time, we make sure the services we make are reliable, well-tested, and diligently reviewed before they run in production. 

Our day begins with a brief stand-up meeting, where we prioritize tasks for the day. During the day, we take turns in the on-call support role to make sure that the trading team can trade at all times. In the afternoon, we keep an eagle eye on code reviews to ensure that nobody’s work is held back by another team member. Most importantly, we do our best to deliver clear and well-tested code. We use up-to-date versions of Python along with a variety of code style checkers, Mypy for type checking, and Orange, our fork of Black, for automatic formatting.

Quantlane maintains a complex infrastructure of services that allow us to deliver data from stock exchanges to our human and algorithmic traders, and back, in a split second. Since every developer is responsible for the whole life cycle of their work, from design, through implementation, to deployment, we can iterate quickly. Diligent code reviews and testing ensure that we always learn from our mistakes.
