01
Network architecture
OPNsense, VLANs, IPv4/IPv6, DNS, routing, firewall policy, VPN, Cloudflare, 10/25GbE, SR-IOV, and DPU data paths.
Tristan Stiller
Electrical and Computer Engineering at Vanderbilt University
I work on networks, virtualized infrastructure, Linux systems, and the tooling that keeps them observable and recoverable.
What I work on
Most of my projects start with real hardware and end with a service I can operate, monitor, repair, and explain.
02
Virtualized infrastructure
Proxmox VE, KVM, LXC, Docker, K3s, PCIe passthrough, storage, backup, recovery, and mixed Linux/Windows systems.
03
Operations and reliability
Prometheus, Grafana, health contracts, alerting, runbooks, change control, rollback, incident diagnosis, and recovery testing.
04
Automation and security
Python, Bash, PowerShell, Git, Ansible, APIs, Wazuh, CrowdSec, Greenbone, telemetry pipelines, and bounded automation.
Selected projects
Four systems that best represent the infrastructure work I have been doing.
01
High-performance virtualized network platform
Designed a segmented Proxmox environment with OPNsense policy, 10/25GbE, SR-IOV, PCIe passthrough, and NVIDIA BlueField integration.
- Device identity, offload, monitoring, rollback, and post-change health encoded in acceptance tooling
- 667 platform tests recorded with 80/80 required non-weather monitoring targets healthy

02
Recovery-first Kubernetes and backup platform
Engineered a heterogeneous K3s platform with Cilium, Hubble, Argo CD, Kyverno, SOPS/Age, Prometheus, and Grafana.
- 21/21 acceptance gates passed with GitOps self-heal and policy enforcement verified
- 74-second worker recovery plus independent encrypted-bundle and PBS restore paths

03
Detection-to-enforcement security pipeline
Integrated Cowrie, Wazuh, threat intelligence, n8n, CrowdSec, OPNsense, Greenbone, Loki, Prometheus, and Grafana.
- Proved proxy and firewall enforcement, alert receipt, rollback, and resource reconciliation
- Validated 4,542 Wazuh rule IDs and preserved nine registered agent identities through upgrade

TNWxLab weather data platform
Built a regional weather ingestion and verification platform around immutable provenance, point-in-time correctness, scheduled workers, and precomputed map assets.
- 1,754 matched precipitation cases across 20 dates and 13 wet events
- Nine animated layers served through a pipeline validated by 206 API and 277 ML tests
