- Implementing Apache Kafka for messaging and data streaming
Achievements:- Development of microservices and REST APIs with Spring Boot and Java 21. Design and implementation of Apache Camel batch processes with management of routes, processors, filtering, transformation, and integration from Greenplum to Couchbase.
- Implementation of Kafka in messaging mode (producer and consumer) to exchange critical business events with other systems, ensuring reliable information diffusion and reception.
- Use of Kafka in streaming mode to continuously process customer update flows (e.g., address changes or contract modifications) and automatically enrich the NoSQL database in near real-time.
- Design of complex Apache Camel routes leveraging EIPs (Content-Based Router, Splitter, Aggregator, Retry, Dead Letter Channel) to ensure the resilience and reliability of batch processes.
- Setting up error handling and incident recovery mechanisms (error handling, redelivery policy, exception management) to ensure the integrity of data flows between Greenplum and Couchbase.
- Optimization of Camel process performance (threading management, route parallelization, JVM tuning) to reduce processing times on large data volumes.
- Application of advanced profiling on the batch using JProfiler to identify and fix bottlenecks, thereby optimizing processing times.
- Automatic generation of service contracts with OpenAPI.
- Orchestration and deployment of applications via Kubernetes and Docker.
