I help enterprises design, build, and operationalize security architectures that protect critical infrastructure without slowing the business down. With deep expertise across Azure, AWS, GCP, and Oracle Cloud Infrastructure, I bring a security-by-design philosophy to every engagement — embedding controls into the architecture itself rather than bolting them on after deployment.
As a CISSP-certified Cloud and Application Security Engineer, I've delivered security outcomes for global enterprises and managed service clients across financial services, healthcare, technology, and aviation sectors. My work spans landing zone design, FortiGate Active-Passive HA deployments via Terraform, Zero Trust Network Architecture, SASE rollouts (FortiSASE, Zscaler ZIA/ZPA), PCI DSS 4.0.1 compliance, and incident response for sophisticated supply-chain and identity-based attacks.
What sets my engagements apart:
I treat infrastructure as code from day one — every FortiGate cluster, Front Door hardening pattern, or hub-and-spoke topology I design is reproducible, version-controlled, and audit-ready. I diagnose root causes rather than patch symptoms, and I deliver client-ready documentation alongside the technical build so your team can operate what I hand off.
Core service areas:
Cloud security architecture and migration across Azure, AWS, GCP, and OCI, including secure landing zones, hub-and-spoke designs, and shared responsibility mapping. Zero Trust and SASE design and implementation using FortiGate ZTNA, FortiSASE, and Zscaler ZIA/ZPA. Enterprise SD-WAN architecture with integrated security controls. Multi-layer defense-in-depth deployments covering perimeter, application, identity, and data layers. Compliance audits and remediation aligned to PCI DSS 4.0.1, NIST CSF, and CIS Benchmarks. Threat intelligence program design, integration with SIEM/SOAR, and security data lake architecture. Disaster recovery design, implementation, and tabletop validation. Vulnerability assessment, management, and continuous posture improvement. Incident response leadership for cloud-native and supply-chain attacks.
Recent enterprise engagements include:
Architecting and deploying FortiGate Active-Passive HA clusters in Azure and OCI using Terraform with strict naming conventions and DR replication. Hardening Azure Front Door, Application Gateway, APIM, and Storage origins to enforce strict client-to-API and client-to-web traffic flows using Web Application Firewall. Leading incident response for Application performance due to the limitation of Microsoft Throttling the connection. Resolving Azure App Service TLS handshake throttling at 8.5M handshakes/minute through Cloudflare proxy migration. Designing privileged access monitoring and passwordless authentication strategies (Windows Hello for Business, FIDO2, CyberArk, BeyondTrust) for RFP responses.
Certifications:
CISSP — Certified Information Systems Security Professional
CEH — Certified Ethical Hacker
ECSA — EC-Council Certified Security Analyst
CASA — Certified AlgoSec Security Administrator
ZTCA — Zero Trust Certified Architect
MCSA — Microsoft Certified Solutions Associate
How I work:
Every engagement starts with understanding your environment, business drivers, and risk appetite — not with a templated solution. I deliver complete, ready-to-use artifacts (Terraform modules, runbooks, architecture decks, compliance evidence packages) and stay engaged through operational handoff. If you're scaling cloud workloads, preparing for an audit, responding to an active incident, or modernizing toward Zero Trust, let's talk about what success looks like for your team.

Hi,
I’m a Systems Engineer with experience supporting a wide range of infrastructure, platforms, and environments. I work across Windows and Linux systems, and I’m comfortable jumping into both ongoing support and full project builds—from troubleshooting and upgrades to planning, automation, and long-term stability improvements.
I can assist with virtualization and hypervisors including Proxmox, VMware vSphere/ESXi, and Hyper-V, along with storage and system performance. I also have experience working with Synology NAS environments, including shares, backups, permissions, and integrating NAS storage into on-prem and virtualized setups.
I’m experienced with containers (Docker and container-based deployments), cloud environments like AWS and Azure, and building practical automation using Ansible, including AWX and Tower, to reduce manual work and keep infrastructure consistent.
I’m also familiar with common web and backend infrastructure such as Apache, MySQL, Redis, and WordPress, whether hosted on-prem or in the cloud.
If you need help with ML/AI tasks I can also be of service. I can help you use openclaw, n8n, ollama,vllm, llm studio, gpu management, bittensor, and more.
My goal is to understand your technical objectives clearly, communicate throughout the project, and deliver a solution that’s stable, secure, and easy to maintain. I have a flexible schedule and strong soft skills, so projects stay organized and moving in the right direction.
Feel free to reach out if you’d like to discuss your project.
Thanks!
Roger
