Development of a high performance, distributed real-time bidding platform, mainly involved with the recommendation engine and ad serving including (but not limited to):• Development of new user and product recommendation profiles and improvement of the existent ones leading to 18%CTR increase.• Reduce memory consumption and infrastructure costs by implementing probabilistic algorithms including bloomfiltering and count-min sketch and optimizing and aligning data structures.• Maintenance of an internal reporting tool for checking advertisers health and products status. This tool turned out to bereally helpful to detect many inconsistencies and problems on the advertisers side.• Contributions to the A/B testing framework and development of an off-line testing framework used by all developers inthe team to assess and select algorithms for A/B testing speeding up the testing cycles.• Migration of several applications to run on the higher level concurrency library, the new protocol for the in-housedatabase engines, D language version 2 leading to performance improvements up to 32%.• Highly involved in trainings, guidance and advice to junior colleagues to the usage of the in-house core libraries andencouraging them to look for the right, flexible and scalable solutions.• Several contribution to FOSS projects (please visit daniel-zullo-sociomantic on Github for more details).• Main tools/technologies: D, Python, Docker, Docker Compose, K8s, Go
