I'm building regulatory financial reporting at Energize Global Services for Worldline, processing 12M+ Oracle rows daily into a centralized data warehouse and generating 100+ scheduled reports each day.
I design Spring Batch pipelines with parallel execution, partitioning, checkpointing, skip/retry logic, and transaction boundaries. I also resolve production bottlenecks through SQL execution-plan analysis, indexing, paging, chunk optimization, and JVM garbage collection tuning.
Previously, I helped transform Ingenico's large monolith into 20 independently deployable services using CQRS, Event Sourcing, Database Per Service, Circuit Breaker patterns, and Kafka-based parallel processing.
I've also optimized high-load Grails/Groovy systems at Webb Fontaine and built secure financial applications across the full SDLC. My core stack includes Java, Spring Boot, Spring Batch, Kafka, PostgreSQL, Oracle, Hibernate, Redis, Docker, and Kubernetes.
