Timothy Gilmore
Software & Infrastructure Engineer
Designing secure systems and building the software to automate them.
About
I design production infrastructure with security built-in from the start and write the automation to keep it running. My environment spans multiple segmented VLANs with block-by-default firewall policies, 14+ hardened Docker containers, and self-healing scripts that diagnose and resolve faults autonomously.
Very few things are as rewarding as tracing a problem to its root cause and resolving it permanently. Troubleshooting enterprise network systems at Colt laid a foundation I built upon while analyzing developmental prototype failures at Safran. Now as I train students to build fault prevention directly into their software, the methodology itself has become second nature reinforcing every system I design.
Skills
Projects
Privacy-First Six-VLAN Network
A six-VLAN network architecture with block-by-default firewall policy, recursive DNS with DNSSEC and ad blocking, and secure remote access via VPN.
Internal PKI & mTLS Infrastructure
A three-tier Certificate Authority with automated certificate lifecycle management, enforcing mutual TLS on all internal service administration.
Self-Hosted Infrastructure Platform
A multi-host virtualization platform built on Proxmox VE (KVM) with PCIe passthrough, Docker Compose containerization, network storage, active real-time malware scanning, and multi-layer backup and monitoring systems.
Experience
Infrastructure Engineer
- Enforce zero-trust network isolation through VLAN segmentation with block-by-default firewall policy and 802.1Q trunking across enterprise-grade networking infrastructure.
- Improve uptime 22% and prevent vulnerabilities through self-healing Bash automation that diagnoses faults, rotates certificates, schedules backups, and applies updates across all hosts.
- Deploy 14+ hardened containerized services on Proxmox VE (KVM) using Docker Compose with PCIe device passthrough and least-privilege security enforcement.
- Secure all internal services through a three-tier PKI with mutual TLS enforcement via nginx reverse proxies, automated certificate rotation, and CRL distribution using OpenSSL.
- Architect encrypted ZFS storage with VLAN-segmented NFSv4 exports, regular VM and filesystem snapshots, and encrypted backup archives across all hosts.
Undergraduate Instructor
- Develop original assignments and course materials covering OOP, data structures, algorithms, and concurrent programming in Java, with comprehensive JUnit test suites for automated evaluation.
- Review code on weekly assignments for classes of 120 to 180 students, providing targeted technical feedback on program design, code structure, and problem-solving approach.
- Lead instruction for two core computer science courses covering OOP, data structures, algorithms, and concurrency, enforcing test-driven development and systematic software design.
Laser Technician
- Qualified developmental Class 4 laser systems for production through precision alignment and systematic testing, contributing to an approximately tenfold improvement in daily throughput.
- Diagnosed and resolved failures in electronics and optical components through systematic root cause analysis, component-level diagnostics, and environmental testing.
- Reported diagnostic findings and proposed solutions in daily stand-ups with systems, optical, and electrical engineers, conducting data analysis to inform design decisions and drive production readiness.
Test Technician
- Increased departmental output by 30% by developing standardized multi-vendor documentation covering authentication bypass procedures, system reset methods, and data sanitization workflows.
- Performed secure data sanitization across enterprise platforms, clearing configuration files, system logs, and credentials following NIST 800-88 data destruction procedures.
- Reconfigured and tested enterprise networking and server hardware from Cisco, HPE, Juniper, and Dell, verifying functionality through POST diagnostics and component-level testing.
Manager
- Increased net profit 91% within one year by analyzing historical sales data to optimize inventory purchasing and eliminate recurring stockouts that had been the primary revenue blocker.
- Improved customer satisfaction 20% by implementing a structured training cascade through 5 shift supervisors and aligning staffing to hourly demand forecasts across a 25-person team.
- Developed weekly, daily, and hourly sales forecasts from historical data to drive inventory purchasing, constraint-based scheduling, and training resource allocation.
Manager
- Delivered 100% compliance across all regulatory audits and quality inspections by implementing standardized operational procedures and maintaining continuous audit readiness.
- Led operations through a national promotional launch that exceeded supply chain projections, maintaining revenue continuity by restructuring workflows and redirecting customer demand to available product lines during extended stockouts.
- Resolved recurring safety and security challenges by developing de-escalation protocols, training staff on risk assessment procedures, and establishing preventive measures that protected team members and reduced operational disruptions.
