- ManoManoStaff / Kotlin & Java Backend Developer / Kafka ReferentE-COMMERCEApril 2023 - Today (3 years and 2 months)Bordeaux, FranceStaff RoleAt ManoMano, I integrated **Kafka-Streams**, a framework with superpowers allowing in very few lines the manipulation of Kafka topics such as message filtering, topic merging, reduction, or grouping, all efficiently and without loss using Kafka distributed transactions.I worked for several months with my team of 3 developers to successfully merge different Kafka topics receiving thousands of messages per second in total at a lower cost, andKafka-Streams was the most efficient and cheapestsolution, allowing the discontinuation of traditional in-house systems using both Kafka, PostgreSQL, and Redis. This optimization resulted in annual savings of tens of thousands of dollars.
