Data Replication and Synchronization

Design and troubleshoot Change Data Capture pipelines using Debezium, Kafka Connect, AWS DMS, and other CDC tools for real-time data integration and streaming.

Design reliable data synchronization pipelines between heterogeneous databases — Oracle to PostgreSQL, MySQL to Snowflake, SQL Server to BigQuery — with schema mapping and transformation logic.

Design and implement conflict detection and resolution strategies for distributed database synchronization, including CRDTs, vector clocks, and custom resolver logic.

Plan and execute database failover and switchover procedures for MySQL, PostgreSQL, Oracle Data Guard, and SQL Server Always On with minimal downtime and data loss.

Design robust database replication architectures for high availability, disaster recovery, and distributed systems across MySQL, PostgreSQL, Oracle, and SQL Server.

Resolve write conflicts, design conflict resolution strategies, and architect multi-master database replication for globally distributed, high-availability systems.

Configure, optimize, and troubleshoot MySQL and MariaDB binlog replication, GTID-based failover, parallel replication, and semi-synchronous replication setups.

Configure and troubleshoot PostgreSQL logical replication, publications, subscriptions, replication slots, and pglogical for selective, cross-version database sync.

Build observability stacks for database replication and data sync pipelines using Prometheus, Grafana, and custom metrics to detect lag, drift, and failures proactively.

Diagnose and resolve database replication lag in MySQL, PostgreSQL, and SQL Server with systematic root cause analysis and tuning recommendations.
