Data Transformation & Enrichment: Implement complex data transformation rules to normalize, enrich, and aggregate data from multiple sources, preparing it for accurate billing and reporting. Automation and Efficiency: Automate mediation processes and workflows within our Kubernetes environment, minimizing manual intervention and improving the efficiency of data flows. Data Integrity and Quality: Ensure data quality by implementing checks, building robust monitoring and alerting systems with Prometheus and Grafana, and creating error-handling mechanisms to prevent inconsistencies, duplicates, or data loss within our streaming architecture. Collaboration with Stakeholders: Work closely with billing, product, and engineering teams to understand data requirements and ensure that our data pipelines align perfectly with business needs.
