I will do performance optimization and tuning

I am a highly skilled Database Administrator with deep expertise in MongoDB security and architecture, including encryption at rest and in transit, authentication mechanisms, role-based access control (RBAC), replica sets, sharding, and high availability. I design and implement robust disaster recovery strategies, ensuring data durability, fault tolerance, and minimal downtime.

I am well versed in database automation, auditing, and high-availability solutions across multiple database platforms, including Microsoft SQL Server, MySQL, PostgreSQL, and SQLite. My experience includes building automated backup and restore processes, performance tuning, patching, monitoring, and failover mechanisms using scripting and scheduling tools.

I specialize in:

Encryption & Security: Transparent Data Encryption (TDE), SSL/TLS, credential management, auditing, and compliance-focused security controls

Authentication & Access Control: AD integration, LDAP, native and role-based authentication models

High Availability & Disaster Recovery (HA/DR): SQL Server Always On, replication, log shipping, MySQL/PostgreSQL replication, MongoDB replica sets

Automation: PowerShell, Bash, SQL Agent jobs, cron schedu
