JULIAN YATESPORTFOLIO

Served as a senior technical authority across multiple commercial and public-sector client engagements, leading infrastructure and security architecture for complex enterprise and regulated environments.

Designed and validated secure, resilient architectures spanning on-premise platforms, hybrid cloud integrations, virtualization, identity, and network security controls. Provided hands-on technical leadership during implementation and migration phases, resolving high-impact systems, networking, and security challenges to ensure solutions were production-ready and operationally supportable.

Acted as a trusted advisor on modernization and transformation initiatives, assessing legacy environments, defining target-state architectures, and guiding phased migration strategies while aligning solutions with security, compliance, and audit expectations.

Founded and operate NetStable, LLC, a Service-Disabled Veteran-Owned Small Business (SDVOSB) focused on secure production architecture for federal and commercial clients. NetStable designs and builds compliant, resilient production environments from architecture through accreditation, with full technical accountability for the outcome.

Current focus areas include compliance-first infrastructure engineering, zero trust architecture aligned with NIST 800-171, identity and access management, and modernization of regulated and high-assurance environments across government and enterprise sectors.

Actively developing two internal platforms: Heliopolis, a secure AI intelligence platform enabling governed use of AI over sensitive data without compromising control or compliance; and NZTN, a zero trust networking platform built for environments where traditional VPNs and cloud-only solutions fall short.

Engaged as enterprise architect to design and deliver a standalone enterprise IT environment for RADA Innovations, a newly established entity within the broader RADA organization. The environment was required to meet the same security, compliance, and operational standards as RADA Technologies while remaining logically and administratively independent.

Led greenfield architecture and implementation across network, security, identity, virtualization, logging, and compliance domains. Defined repeatable enterprise architecture standards, enforced isolation and trust boundaries, and ensured parity with existing security controls and governance frameworks.

Delivered architecture, documentation, and operational patterns designed to support R&D activities, organizational separation, and future scalability, while maintaining readiness for regulatory scrutiny and acquisition activities.

Served as the primary enterprise architect responsible for the design, build, and long-term security governance of RADA Technologies' enterprise IT environment. Engagement began with greenfield architecture and expanded into sustained operational oversight, compliance alignment, and platform standardization through organizational growth and acquisition by Leonardo DRS.

Defined and governed enterprise architecture across network, compute, storage, identity, security, automation, and observability domains. Designed and operated Palo Alto Networks firewall architecture, VMware-based virtualization platforms, enterprise identity services, PKI, centralized logging with Splunk, and vulnerability management processes aligned with NIST 800-171 and CMMC requirements.

Acted as the final technical authority for architectural decisions, risk posture, and compliance readiness. Transitioned engagement from project-based consulting to a retainer model, providing continuous architectural governance, security operations oversight, and technical continuity through acquisition.

Engaged to lead architecture and feasibility analysis for a proposed classified multi-level security (MLS) network supporting U.S. Navy mission requirements. Scope focused on evaluating technical viability, security models, segmentation strategies, and architectural approaches rather than full implementation.

Conducted assessment of existing constraints, risk factors, and applicable security control frameworks to inform architectural options for MLS design. Produced architectural recommendations and supporting design artifacts to guide decision-making, future implementation planning, and accreditation considerations.

Partnered with government stakeholders and prime contractor teams to ensure proposed approaches were technically sound, operationally feasible, and aligned with Navy security and compliance expectations.

Served as senior infrastructure and security architect supporting FinCEN's regulated enterprise environments. Led architecture, implementation, and operational oversight of secure infrastructure platforms aligned with federal regulatory and compliance requirements.

Designed and implemented segmented infrastructure and security architectures supporting controlled access, system isolation, and audit readiness. Provided hands-on technical leadership across day-to-day operations, troubleshooting complex infrastructure and security issues while maintaining service continuity in a mission-critical environment.

Partnered with government stakeholders and prime contractor teams to align architectural decisions with compliance, risk management, and operational governance expectations.

Engaged for a design-led implementation supporting U.S. Air Force infrastructure and security initiatives. Translated mission and security requirements into segmented, production-ready infrastructure and network security architectures aligned with accreditation and compliance expectations.

Designed and implemented security enforcement and segmentation models to support controlled access, system isolation, and operational readiness. Worked closely with Air Force stakeholders and prime contractor teams to ensure solutions were technically sound, supportable, and mission-aligned.

Served as senior infrastructure and security architect responsible for the end-to-end design and implementation of a highly segmented, secure enterprise environment supporting DARPA research and mission operations.

Architected and delivered a domain-driven infrastructure and network security model, separating identity services, management platforms, security tooling, and user workloads into rigorously controlled trust zones. Implemented security-centric segmentation and access control architectures enforcing inter-domain communication through centralized policy and inspection mechanisms.

Led hands-on implementation across systems, virtualization, networking, and security layers to ensure the environment was deployable, resilient, and operationally stable. Produced architecture documentation and technical artifacts supporting security assessment, accreditation, and operational handoff.

Served as senior infrastructure and security architect supporting USAID enterprise environments within a regulated federal context. Contributed to architecture, design, and implementation of core infrastructure, virtualization, and network security solutions supporting development, test, and production environments.

Designed and implemented foundational systems and platform architectures, integrating identity services, core infrastructure components, and security controls to support operational stability, access control, and compliance requirements. Supported firewall and segmentation strategies under the direction of lead security architects while maintaining strong hands-on technical involvement.

Produced architecture documentation, technical diagrams, and implementation artifacts to support operational handoff, audit readiness, and long-term maintainability.

Built a deep technical foundation in enterprise infrastructure, networking, virtualization, and security across commercial and early federal environments. Experience spanned systems engineering, network administration, security operations, and platform support roles, with increasing responsibility for design, implementation, and operational stability.

Developed hands-on expertise in Windows and Linux systems, virtualization platforms, core networking, identity services, and perimeter security controls. Supported environments subject to regulatory, security, and audit requirements, establishing disciplined operational practices and documentation standards that later informed senior architecture and design authority roles.
