Provided secure, compliant financial operations support by managing customer incidents, protecting sensitive data, and enforcing regulatory and access control standards. Demonstrated strong incident handling, documentation accuracy, and risk awareness while promoting cybersecurity hygiene and secure account practices across all customer interactions.

• Utilized ticketing and case management systems to triage and document customer incidents while adhering to SLA, regulatory, and security requirements, ensuring accurate records and reducing operational risk.

• Protected sensitive financial information by enforcing identity verification procedures, access control policies, and data confidentiality standards, while educating customers on secure account management and digital banking safety practices.

Delivered secure infrastructure engineering and deployment across enterprise Windows and Linux environments, integrating configuration baselines, encryption, and compliance-aligned hardening. Supported large-scale provisioning, network optimization, and post-deployment validation to ensure system reliability, security, and operational continuity.

• Executed automated imaging, provisioning, and configuration management using SCCM, Clonezilla, and PXE solutions to standardize builds, accelerate rollout timelines, and maintain consistent, compliant system baselines across enterprise infrastructure.

• Installed, patched, and validated switches, routers, and firewalls while collaborating with system and network engineering teams to resolve configuration issues and optimize LAN and WAN performance, contributing to a twenty-five percent reduction in system downtime and strengthening overall security posture.

Delivered enterprise-level endpoint security engineering across macOS, iOS, Windows, and hybrid environments by deploying secure provisioning, identity protection, and Zero Trust-aligned controls at scale. Strengthened organizational security posture through vulnerability reduction, system hardening, threat detection, and cross-functional collaboration with cybersecurity, DevSecOps, and engineering teams.

• Implemented automated patching workflows, EPP and EDR enforcement, secure configuration baselines, and NIST and CIS-aligned controls while conducting SIEM correlation, SQL audit review, and endpoint telemetry analysis to reduce attack surface and enhance incident response readiness across thousands of devices.

• Supported secure lifecycle management by applying network segmentation, least privilege identity governance, and detailed SOP and response playbook development while ensuring compliant deployment, data protection, and secure disposal procedures for more than one thousand seven hundred enterprise endpoints each quarter.

Supported automated manufacturing and operational technology environments by securing PLCs, MES platforms, and industrial control systems, ensuring uptime, data integrity, and safe system performance. Applied secure troubleshooting, firmware and hardware validation, and NIST-aligned control practices to strengthen cyber-physical security and reduce operational risk across connected production systems.

• Collaborated with IT and engineering teams to diagnose ICS and network device issues while enforcing access control, network segmentation, and data protection policies to safeguard operational environments from internal and external threats.

• Followed strict SOPs, change control procedures, and NIST and ISO 9001 compliance requirements to minimize system risk, maintain audit readiness, and promote a security-aware, safety-focused culture within OT operations.
