Database Expertise: Performance Tuning & Solutions
I am a seasoned Database Administrator with 20+ years of experience managing, tuning, and troubleshooting mission-critical databases across Oracle, SQL Server, PostgreSQL, MySQL, and cloud platforms (AWS, Azure, Google BigQuery). I specialize in performance optimization—identifying issues within minutes and implementing solutions that restore speed, stability, and reliability. My core strengths include: Performance Tuning & Troubleshooting: SQL query optimization, indexing, partitioning, memory/I/O tuning, and real-time issue resolution. Database Administration: Installation, upgrades, backup/recovery, high availability (RAC, Always On, replication), and security hardening. Data Architecture & Warehousing: Designing scalable schemas, star models, and ETL pipelines for BI and analytics. Business Intelligence Integration: Power BI, Tableau, SAP BO, and advanced reporting solutions. I deliver robust, secure, and high-performing database environments that empower organizations to scale confidently and make data-driven decisions. Whether on-premises or in the cloud, I ensure your systems run at peak efficiency with minimal downtime.
