Our efforts are geared towards improving and further developing one of the biggest self-service marketing platforms. This is done by focusing on data pipelines, data visualization, machine learning, and platform usability.</p> <p>We use the infrastructure of AWS, Amazon web services, and its corresponding products—such as Dynamo, Kinesis, EC2, VMR, EMR, and S3—to serve 50 billion ad impressions per day, to scale very quickly in new markets, and to develop products whole lot faster. This in turn allows our engineers to divert most of their attention towards building products and helping businesses grow. Additionally, with the use of pixels, we use our internally built open-sourced library <a href="http://traildb.io/">TrailDB</a> and cross-device graph to map interactions into a holistic customer journey.</p> </div> </section> <a class="scroll-anchor" name="teams"></a> <section id="teams-section"> <div class="wrapper"> <header> <h2>Teams</h2> </header> <ul> <li> <article class="rtb"> <header> <h3>RTB</h3> </header> <div> <div class="content"> <p>This team works on the infrastructure to purchase the ad space inventory.
