Enabled end-to-end application visibility by integrating OpenTelemetry with Azure Monitor, reducing mean time to resolution (MTTR) and accelerating root cause analysis. Implemented a DevSecOps approach, reducing security vulnerabilities by 40% through automated security scans and proactive mitigation strategies. Optimized application stability by adopting Blue-Green deployment, minimizing downtime and ensuring seamless releases. Integrated Databricks with Git, enabling automated job workflow synchronization. Designed a custom sync policy to manage multiple job types efficiently. Led the migration of Git repositories from Bitbucket to GitHub, preserving full commit history and streamlining development workflows for improved efficiency.

Developed a Python-based automation solution to synchronize network data between VMware vSphere and DCIM software, ensuring accurate tracking of clusters, hosts, VMs, IP assignments, and host-switch connections. Initiated Ansible automation for vSphere cluster configuration, integrating with DCIM to streamline deployment and configuration processes. Optimized vRealize Operations (vROps) reports, enhancing billing accuracy and resource allocation efficiency.

Implemented enterprise-grade backup and disaster recovery by deploying Veritas NetBackup across two branches, designing and documenting a 3-2-1 backup strategy. Improved backup efficiency 4x by integrating HPE StoreOnce with Catalyst deduplication. Modernized virtualization infrastructure, transitioning from HPE C7000 blade chassis to rack-mounted HPE servers with high-speed Cisco Nexus switching. Enhanced IT monitoring and incident response, reducing system alert noise and improving failure detection. Optimized virtualization efficiency using vRealize Operations 8.0, improving resource allocation and reducing underutilized capacity across multiple data centers. Automated IT processes with PowerShell, streamlining administration and operational tasks. Provided the security department with detailed connection source reports through a custom solution integrating MS SCOM and Active Directory, ensuring every connection attempt was logged. Shared technical expertise in VMware vSphere and Excel macros with numerous employees.

Restored a large-scale Active Directory environment after a critical failure, ensuring stability across 100 domain controllers and multiple sites. Optimized the Active Directory setup by reducing the number of domain controllers from 100 to 60 and minimizing the NTDS.DIT database size from 16 GB to 3.5 GB. Boosted thousands' employees productivity through ongoing enhancements to VoIP and messaging solutions, including MS Exchange and MS Skype for Business. Consistently maintained the stability of the virtual infrastructure by supporting and upgrading VMware vSphere from version 4.1 to 6.5. Ensured up-to-date hardware and software use by designing and leading the migration of factory infrastructure from VMware VI 3.5 to VMware vSphere 6.7.

Enhanced email system maintainability by migrating from MDaemon to MS Exchange 2003. Improved infrastructure reliability by upgrading to VMware vSphere 4.0 and incorporating HP BladeSystem C3000 and HP EVA 4400. Built a stable foundation for client Internet access using Cisco hardware. Secured consistent data protection and security by enabling backups with Veritas BackupExec and Veeam Backup & Replication.

Enhanced infrastructure reliability by implementing and migrating servers to VMware Virtual Infrastructure 3.5. Enforced network policies on VMware virtual networks by installing and configuring Cisco Nexus 1000v.

Rapidly set up a secure and resilient IT infrastructure, critical for the launch of two car showrooms, leveraging expertise in Active Directory and MS ISA 2004 with Site-to-Site VPN capabilities. Applied ITIL practices to streamline request management, reducing response times to just two days.

I learnt programming and mathematical science such as statistics and analysis.
