At Kcell, I redesigned a telemetry ingestion pipeline on Amazon MSK, increasing throughput about 2.5x on the same cluster size and bringing peak consumer lag below 40 seconds. I also reworked storage across ClickHouse and S3, reducing the storage footprint about 4x.
At Bank CenterCredit, I designed and shipped a payment refund module coordinating four services, and used the Transactional Outbox pattern and idempotent Kafka consumers to reduce reconciliation discrepancies. Earlier, at Dara Solutions, I developed document search and filtering for an electronic document management system, bringing search time to about 400ms.
