Database and Virtual Infrastructure Recovery Specialist focused on complex corruption, failure, ransomware-related, and inaccessible-data incidents in enterprise environments.
My work is centered on assessment, recoverability analysis, controlled recovery, and data export for business-critical databases and virtual infrastructure.
Core expertise:
• Microsoft SQL Server Recovery — database corruption assessment, damaged MDF/NDF analysis, suspect or inaccessible databases, structural analysis, data reconstruction, recovery validation, and SQL/data export.
• Oracle Database Recovery — corruption and recoverability assessment, damaged or inaccessible Oracle database environments, recovery analysis, validation, and structured recovery planning.
• VMware & Hyper-V Recovery — analysis and recovery of damaged or inaccessible virtual disks and virtual machine data, including VMDK and VHDX, virtual disk structures, filesystem-level assessment, and recovery of required data.
• Ransomware-Affected Data Recovery — technical assessment of databases and virtual infrastructure affected by encryption, corruption, incomplete recovery, or post-incident damage.
Additional enterprise expertise includes database administration, high availability, disaster recovery, backup and restore, performance optimization, infrastructure diagnostics, Windows Server, VMware ESXi, Microsoft Hyper-V, SQL Server HA/DR, business continuity, and technical recovery reporting.
My recovery workflow is evidence-driven:
Assessment → Technical Evidence / Report → Client Approval → Recovery / Export
I focus on determining what is recoverable before recovery work begins, preserving the original source data, defining a controlled recovery scope, and providing clear technical findings for client decision-making.
Available for project-based B2B recovery assignments, remote technical assessments, database recovery, infrastructure recovery, and complex incident analysis.
