▪ Designed from scratch to production a campaign report collector for ads campaigns. The project aimed to automate the process of generating a campaign report, in addition, to facilitate the customer success team to track the progress of a running campaign. The system was composed of three concurrent cronjobs that consume from external API's and aggregates data to be presented on Tableau, Java was the main language, and data was stored on Postgres. As a result of the project, the friction of manually generating reports and following it to a campaign owner was eliminated, besides, it also allowed the tracking of a running campaign with partial reports feature, making the process of managing a campaign more accurate. ▪ Maintained a legacy real-time Ad Exchange system that handles a great volume of requests per second, the main work was to refactor the entire system to encrypt and hash sensible data.
