I’m a database specialist with over 14 years of experience in the field, including more than a decade as a dedicated DBA. My expertise spans SQL Server (from 2005 through 2022), MySQL (5.7 and 8.0), and MongoDB (3.4 through 5.0). Throughout my career, I’ve managed and optimized databases reaching over 20TB in size. I’m particularly skilled in performance tuning, troubleshooting complex issues, and implementing robust solutions to ensure data integrity, scalability, and efficiency.
