• Design upgrade and migration strategies for databases ranging from hundreds of gigabytes to multiple terabytes.
• Lead in-place upgrades, logical and physical migrations, replication-based migrations, Blue/Green deployments, and AWS DMS-based migrations.
• Perform upgrade readiness assessments covering compatibility, deprecated features, SQL modes, drivers, plugins, stored procedures, triggers, events, and application dependencies.
• Create upgrade runbooks, rollback plans, validation checklists, risk assessments, implementation plans, and stakeholder communication plans.
• Conduct pre-and post-upgrade validation, including row counts, checksums, reconciliation queries, performance benchmarking, and application testing.
• Coordinate production upgrade and migration activities with application, infrastructure, cloud, security, DevOps, QA, compliance, and business teams.
• Troubleshoot upgrade failures, replication lag, data inconsistencies, performance issues, locking, deadlocks, and application connectivity problems.
• Manage cutover planning, release windows, freeze periods, rollback decisions, post-migration monitoring, and production hyper-care.

• Administer and support MySQL databases on AWS, including Amazon RDS for MySQL, Amazon Aurora MySQL, Aurora PostgreSQL, EC2-hosted databases, and AWS Database Migration Service.
• Manage Multi-AZ deployments, read replicas, snapshots, automated backups, point-in-time recovery, parameter groups, option groups, cluster upgrades, and Aurora Blue/Green deployments.
• Monitor performance, replication health, capacity, storage growth, availability, security controls, audit logging, encryption, access policies, credential rotation, and AWS database costs.
• Support MongoDB environments, including replica sets, sharding, backups, restores, indexing, performance, upgrades, migrations, monitoring, and security practices.
• Administer Aurora PostgreSQL clusters and support PostgreSQL upgrades, failover, backups, monitoring, performance analysis, replication, autovacuum, indexing, partitioning, and query optimization.

• Monitor and tune MySQL performance in high-volume transaction environments using slow query analysis, execution plans, indexing, partitioning, configuration tuning, and workload analysis.
• Manage high availability, disaster recovery, replication, failover, recovery testing, operational health checks, monitoring, alerting, capacity planning.
• Support asynchronous, semi-synchronous, GTID-based, and read-replica architectures.
• Handle critical incidents, root-cause analysis, permanent corrective actions, and production escalations.
• Support databases for digital lending, loan origination, loan servicing, payments, collections, credit decisioning, customer communications, and other financial-services workloads.
• Ensure database changes follow change management, security, compliance, audit, and release management processes.

• Strong hands-on MySQL database administration experience, including MySQL internals, storage engines, transactions, replication, locking, indexing, query optimization, backup, restore, recovery, failover, and disaster recovery.
