PROFILE
Rafal Dekarz
Worked on the utilitywarehouse/kafka-cluster-config repository to design and implement robust Kafka-based infrastructure for card processing, payments, and notification workflows. Delivered features such as multi-topic Kafka architectures with dead-letter queues, settlement event streaming, and dedicated consumer pathways for transaction logs, all provisioned using Terraform and HCL. Enhanced reliability and security by integrating TLS modules, configuring retention policies, and introducing indexer-based consumption for card notifications. Focused on Infrastructure as Code and DevOps practices, the work improved data governance, observability, and fault tolerance across payment and card domains, enabling scalable, resilient event-driven systems for production and development environments.

Sep 1, 2025September 2025: Delivered Card Notification Messaging Infrastructure with Kafka Topics and Indexer-based Consumption in utilitywarehouse/kafka-cluster-config. Added new Kafka topics (primary and dead-letter) for card notifications and integrated them into production and development configurations for card_api, card_consumer, and payment_deadletterd. Refactored Kafka cluster configurations to remove the dead-letter topic for card notifications and introduced an indexer module to consume card notifications, optimizing delivery via an indexer. All changes are anchored to FPAY-1922 with commits 187cd0cff9f08d5a79719a0bd0b9118863cac23e and 5996b74f242befe51b94cc75c7717720cfabd7d0.

Aug 1, 2025August 2025 monthly summary for utilitywarehouse/kafka-cluster-config: Delivered a dedicated Kafka consumer pathway for transaction logs in the Downstream Payment Query Service, enabling isolated processing separate from existing payment events. Implemented via Terraform in production with a new consumer group for downstream transaction logs and linked commits for traceability. No major bugs fixed in this period. Impact: improved data reliability and scalability of transaction log processing, reduced risk of impacting payment event processing, and enhanced observability. Technologies/skills demonstrated: Kafka consumer group configuration, Terraform provisioning for production environments, production rollout practices, commit traceability.

Jan 1, 2025January 2025: Delivered core Kafka-cluster-config enhancements for reliability, security, and cross-service data flows. Implemented settlement event streaming with a main settlements topic and a dead-letter topic, configured retention and tiered storage, and integrated these topics across producer/consumer configurations in related services (commit 2068e6f9afa08deb46e7e48cb0c9533f8cc72996). Added TLS-enabled modules for Card API and Card Consumer with dedicated producer/consumer topics for payment processing to secure and streamline card-related data flow within the Kafka cluster (commits 397f36bf6baa5746e91270c073eb5edaa1a545f6 and d52d620f2a7bddd5bb01e355f8383da664e5e8b5). Fixed naming inconsistency by renaming the module from card_apid to card_api and updating the certificate common name to ensure accurate resource identification (commit ec ded412dec1436cd3d29829e2f9f113d1df4565).

Nov 1, 2024November 2024 (2024-11) - Delivered the Cards v2 Kafka topics architecture in utilitywarehouse/kafka-cluster-config. Implemented six Kafka topics (main topics and dead-letter queues) for general card operations, 3D Secure authentication, and payment methods, with configurations for compression, retention policies, and tiered storage to enable robust, scalable data handling. This work supports Cards v2 rollout with improved reliability, data governance, and error handling. The change is tracked in commit a65c8cd0968ebaec628958dc88361fbf198892ac (Added kafka topics for cards v2 architecture (#703)). No major bugs were reported in this period; all changes were focused on feature delivery and stability.
