Experienced and detail-oriented Senior Database Administrator with over 6 years of expertise in managing complex SQL Server environments (2014–2022). Proven success in designing, optimizing, and securing large-scale databases for performance, availability, and disaster recovery. I have implemented mission-critical high availability (HA) and disaster recovery (DR) solutions including AlwaysOn Availability Groups, Log Shipping, and Clustering. Skilled in performance tuning, backup & recovery strategies, migrations and security compliance (TDE, role-based access, auditing). With a background in Physics and a deep technical foundation, I combine analytical thinking with hands-on database management and cloud integration expertise. I am open to both remote and on-site opportunities where I can contribute to database performance, integrity, and availability.
