PostgreSQL: data modeling, schema evolution, migrations, query optimization, indexing, transactions, high availability, backup/restore, and replication.\nExperience migrating legacy data platforms, preferably MySQL and MongoDB to PostgreSQL and/or managed cloud data services, with validation, reconciliation, rollback, and minimal-downtime approaches.\nExperience with event-driven architecture, asynchronous processing, queues, and streaming platforms such as Kafka, Kinesis, RabbitMQ, SQS, or equivalent.\nExperience building ETL/ELT, data-ingestion, document-processing, and API-integration
