[SYSTEM STATE: OPERATIONAL] OPERATOR: ZACHARY HEITLING [LOC: CENTRAL FLORIDA, USA] DISCIPLINE: TECHNICAL SUPPORT ENGINEERING / NOC / SECURITY OPERATIONS STATUS: ACTIVE [REMOTE / HYBRID / DEFENSE] SUITABILITY: U.S. CITIZEN | HONORABLE NAVAL VETERAN

Architecting autonomy. Hardening infrastructure. Executing with precision.

This environment is for technical triage leads, engineering managers, and operations teams who care about how systems are built, monitored, and defended in practice. Everything documented here is backed by bare-metal Linux instances, live containerized services, and structured operational drills. Nothing is theoretical—if it is listed, I have deployed it, broken it, analyzed it, and engineered the resolution.

[01_CREDENTIALS & TECHNICAL FOUNDATION]

CompTIA Security+ (SY0-701)

CompTIA Secure Infrastructure Specialist (CSIS Stack)

CompTIA Network+

CompTIA A+

U.S. Navy Advanced CASS School (Aviation Electronics & Component Diagnostics)

Everything listed represents verified hands-on operations and reproducible technical workflows down to the packet header, routing table, and log line. No inflated titles, no borrowed war stories.

[02_CORE_INFRASTRUCTURE: KURO KYOMU BASTION]

Hardened production environment governing ownchain.systems since 2024:

Edge Routing & Ingress: Zero inbound open firewall ports. Ingress terminated and proxied securely via Cloudflare Tunnels (cloudflared) and containerized Nginx reverse proxies over HTTPS/SSH.

Workload Isolation: Multi-container microservices orchestrated via Docker on Alpine Linux.

Telemetry & Metrics: Continuous observability stack streaming real-time host metrics, latency, and resource utilization through Prometheus and Grafana dashboards.

Disaster Recovery Pipeline: Automated multi-tier backup utilizing an internal REST daemon piping encrypted snapshots to Backblaze B2—enforcing the golden rule that a backup is only trusted once a cold restore boots.

[03_PROVEN OPERATIONAL TRAJECTORY]

A consistent track record of rapid merit-based advancement and technical execution across high-stakes environments:

Enterprise Operations | Newman Communications (2020 – 2024)

Orchestrated operational and logistical workflows for 120+ client accounts, coordinating real-time media outreach and technical logistics for high-profile figures including cybersecurity veterans Mikko Hyppönen, Robert Kerbeck, and Christopher Hadnagy. Automated cross-platform workflows to reclaim 20+ hours weekly and reduce coordination friction by 30%.

Regulated Systems Support | Dexcom (2015 – 2019)

Promoted in 90 Days: Selected within the first quarter from frontline Technical Support Representative I to Business Services Representative I (managing enterprise B2B accounts and high-touch B2C escalations). Conducted structured root-cause isolation across proprietary hardware, mobile operating system synchronization, and cloud endpoints under rigorous FDA/HIPAA compliance standards.

Broadband & Network Operations | Cox Communications (2003 – 2011)

Merit Ascension: High-Speed Internet Tier I Support → Tier II Escalations → Technical Operations Center (TOC). Monitored regional network health, headend infrastructure, and RF/signal integrity; isolated Layer 1–3 faults across fiber-coax distribution plants and managed enterprise outage mitigation.

High-Reliability Foundation | U.S. Navy (1995 – 1998)

Aviation Electronics Technician (AT3). Executed component-level troubleshooting, radar/avionics calibration, and electronic warfare system repair on Consolidated Automated Support System (CASS) test benches under zero-defect operational mandates.

[04_BASTION CODEX: INCIDENT & HARDENING LOGS]

Real-world operational drills, root-cause investigations, and architectural hardening:

• CODEX-001: Decommissioning Socket-Mounted Web UIs

  • Focus: Eliminating attack surface by revoking /var/run/docker.sock container mounts, tearing down Portainer, and migrating container ops strictly to terminal-native TUIs over encrypted SSH.

• CODEX-002: Hardening the Domain Mail Perimeter (SPF, DKIM, DMARC)

  • Focus: Troubleshooting transactional dropouts, aligning multi-service envelope senders, and enforcing hard DMARC quarantine policies with automated telemetry monitoring.

• CODEX-003: Container Lifecycle, Layer Drift & Database Migrations

  • Focus: Managing automated Laravel schema migrations, resolving parallel layer pull race conditions, and executing zero-downtime stack updates.

• CODEX-004: Validated Backups & Disaster Recovery Drills

  • Focus: Client-side encrypted offsite pipelines and the operational rule of only trusting a backup once a cold restore actually boots.

• CODEX-005: Sandboxing vs. Storage Vaults: Flatpak, AppImage, and Native Packaging

  • Focus: Diagnosing container sandbox permission boundaries, FUSE execution limits on encrypted storage vaults, and evaluating native runtime integration.

• CODEX-006: Hybrid GPU Provider Synchronization & GUI Kernel Recovery

  • Focus: Troubleshooting xrandr display provider synchronization failures on hybrid discrete paths, driver stack rebuilds, and recovering from session manager collapses.

• CODEX-007: Digital Identity Excision & Data Broker Surface Reduction

  • Focus: Executing systematic Right-to-be-Forgotten account excisions and deploying continuous data broker countermeasures to reduce external threat surface.
