I worked closely with the Paid Marketing team to build Python based services that helped us run world-class advertising campaigns. I dealt with large volumes of data using a variety of ETL technology (backed by S3, Redshift and ECS clusters), and then made it available for the business and other components of our software to use. I also worked with front-end technologies such as a custom JavaScript Tag Management solution that serves millions of customers per month. My closeness to the advertising space further allowed me to digest and articulate complex business-domain challenges and put them into empowering work-streams for my colleagues to contribute toward.
