• Methodical and precise work ethic to ensure data consistency and scalability within the Kafka and Elastic architecture.
• Ability to work autonomously, propose solutions, and adapt quickly to changes in the situation.
• Strong documentation skills to clearly and structurally document analyses, pipelines, schemas, configurations, and technical choices (reports, documentation).
