Welcome—and thanks for being here. I'm a Staff Software Lead, with 15+ years in Java. For the last few years, I've lived in event-driven, distributed systems.
I build real-time platforms for financial infrastructure—streaming on Apache Kafka and Apache Flink, handling strict ordering, exactly-once processing, watermarking, and schema evolution with Avro.
I've built reconciliation pipelines for core banking, where a lost event isn't a bug—it's a financial discrepancy. I also led one platform's shift to a SaaS-ready, multi-tenant product, deployed globally.
I own the full lifecycle: Kafka topology, consumer lag, Flink state tuning, CI/CD for streaming jobs, plus the surrounding architecture—Cassandra, Oracle, Spring Boot.
Low-level design matters to me: clean class structures, solid interfaces. Systems fail at the seams, so I weigh trade-offs constantly—consistency vs. availability, throughput vs. latency.
I stay hands-on, shipping code and solving hard consistency problems, while also leading teams and mentoring engineers.
