>Architect and own the dbsync data pipeline in Java 24, synchronising 35 telecom IRDB reference tables from Oracle and Couchbase into a multi-node ClickHouse cluster with zero-downtime atomic table swaps (EXCHANGE TABLES ON CLUSTER), row-count validation, and flock-based concurrent-run locking; integrated into the RAID Kubernetes scheduler as a fat JAR replacing a legacy PF4J/Hive plugin. >Led cloud migration of on-premise applications to Kubernetes (EKS/OCP), reducing deployment complexity by 30% and enabling one-command deployment across multi-cloud environments. >Designed and delivered Revenue Share Calculator (RSC) microservice in Spring Boot, processing terabyte-scale roaming revenue data with ClickHouse-optimised multi-database integration, stream-based CSV export, and JSON config management, achieving 10–100× performance improvement over the prior system.

>Developed 10+ Trino scalar functions in Java (HDFS, S3, Azure, GCS connectors) with in-memory caching, eliminating JOIN operations by 50% and accelerating query performance by 90% across multi-cloud data lakes. >Drove end-to-end migration of Proteum (Java/Spark) Data Warehouse from Java 8 → 22; containerized on Kubernetes with multi-cloud storage support (S3, GCS, Azure) replacing HDFS, reducing storage costs by 20% and collapsing a multi-step deployment to a single command. >Led Apache Hive → ClickHouse migration by building a production-ready custom connector, Docker image, and Helm chart delivering 3× faster query performance and up to 40% infrastructure cost reduction. >Engineered Node.js/Playwright service automating dashboard PDF generation and scheduled email distribution, reducing manual reporting overhead by 85%; containerized and deployed with Docker and Kubernetes Helm charts. >Optimised view creation logic to remove redundant caching layers, reducing processing overhead by 30%.
