About

Experienced Senior Technical Consultant specializing in Enterprise IT, SAP Basis administration, cybersecurity, and cloud infrastructure. With a proven track record supporting business-critical systems, I bring hands-on expertise across SAP landscapes, virtualization platforms, firewall security, and cloud-based disaster recovery solutions.My core strengths lie in managing SAP S/4HANA environments, including Fiori app deployment, user/authorization management, transport configuration, system monitoring, and database administration (HANA & Oracle). I’ve implemented and supported HANA System Replication (HSR) for DR and worked across diverse SAP landscapes ensuring high availability and performance.In the area of cybersecurity, I manage enterprise-level protection using CrowdStrike Falcon EDR, Exposure Management, and NGSIEM platforms. I collaborate closely with SOC teams for proactive threat detection, guided remediation, and endpoint security policy implementation. I'm also responsible for FortiGate firewall and VPN management, ensuring network access is secure and compliant.Cloud proficiency includes managing both SAP and non-SAP workloads on AWS and Oracle OCI. I've deployed Elastic Disaster Recovery (AWS DRS) for critical systems and support full lifecycle management of cloud infrastructure — from provisioning to monitoring and backup.In addition, I handle core IT infrastructure: VMware ESXi and vCenter administration, Dell and HP enterprise hardware, storage systems like Dell PowerStore and Data Domain, and backup technologies using EMC Networker with DD6400 and IBM Tape Library. I’ve also led email migrations to Microsoft 365, including multi-domain GoDaddy-to-M365, Google one-to-M365 transitions.I am continuously focused on improving systems, automating operations, and strengthening security posture — ensuring resilient, scalable, and efficient IT environments.Let’s connect if you're looking for someone with deep technical experience across SAP, IT infrastructure, security, and cloud platforms.
