Personal summary

Ning Zhu – Senior Database Administrator & Developer I am an experienced IT professional with over 15 years of expertise in database management, development, and cloud migration. Specializing in Oracle, MSSQL, and MySQL, I have a strong background in database performance tuning, high availability solutions, and cloud platforms such as Azure and AWS. Throughout my career, I have successfully led large-scale database migrations, including converting IBM DB2 databases to Oracle and MSSQL, as well as migrating on-prem databases to Azure and Oracle Cloud Infrastructure (OCI). I have extensive experience in ETL development, data warehousing, and BI reporting, ensuring data integrity and optimizing enterprise data systems. I have worked across multiple industries, including government, manufacturing, and healthcare, where I played key roles in designing and maintaining mission-critical database environments. My technical skills cover database security (Transparent Data Encryption), automation (RMAN, PowerShell, Python), and performance tuning (query optimization, indexing, and database monitoring). Additionally, I have hands-on experience in DevOps methodologies, version control systems like Git, and server administration across Windows, Linux, and Unix platforms. Holding certifications such as Oracle Certified Professional (OCP), Microsoft Certified Database Administrator (MCDBA), and MCTS in SQL Server, I continue to leverage my expertise to drive technological advancements, improve data-driven decision-making, and mentor junior IT professionals.
