Senior systems engineer and Army veteran building AI systems that hold up in the real world — offline-first field tools, guardrails for coding agents, and pipelines that handle messy data in constrained environments. Twelve years across IT, network engineering, and full-stack development.
Everything here is independent side work, built on my own time, MIT licensed.
Five connected projects built as one field-engineering workflow: realistic source data, measurable cleanup, RAG evaluation, offline delivery and database drift detection.
| Project | What it proves |
|---|---|
acme-parts-cloud |
One-command synthetic enterprise API, UI, Postgres data, deterministic messiness and manifest-v2 ground truth |
fde-data-forge |
Exact row-key defect scoring with published recall, precision, F1, false positives and misses |
rag-eval-bench |
Retrieval metrics, unanswerable-question scoring, refusal behavior, a versioned judge rubric and a blinded human-agreement workflow |
air-gap-deploy-kit |
Explicit offline bundles, standalone transfer verification and fail-closed rehearsal with image pulls and networking disabled |
pgdrift |
Deterministic Postgres schema snapshots and categorized drift detection for CI and field debugging |
Built around the constraint that the network may not be there and the data may not be clean.
| Project | What it proves |
|---|---|
field-sync-notebook |
Offline-first sync with local queuing and degraded-connectivity recovery |
edge-lab-console |
Full-stack telemetry + config-drift tracking for edge deployments |
telemetry-replay-studio |
Run comparison, outcome scoring, and handoff export for post-mission analysis |
| Project | What it proves |
|---|---|
agent-security-kit |
Guardrails for AI coding agents — secret-leak blocking, dangerous-command hooks |
ollama-model-router |
Automatic model selection by prompt type; no manual switching |
claude-code-recipes |
Production patterns for the Claude Code SDK: rate limits, memory, MCP, parallelism |
ai-ops-runbook |
Paste an alert, get a structured operational runbook — LLM-generated, ops-reviewed |
workspace-search |
Local-first RAG over personal docs; no cloud, no account required |
awesome-ollama-models |
Curated free Ollama-compatible cloud models with benchmarks and use cases |
Training environments for automation and infra depth. No real hardware required.
| Project | What it proves |
|---|---|
intent-config-workbench |
Intent → deterministic config artifacts with reviewable diffs |
ansible-convergence-lab |
Ansible automation training without a control node or real hosts |
ansible-wsl-playbook-runner |
GUI runner for Ansible playbooks on WSL — bridges the Windows sysadmin gap |
gitlab-ci-study-lab |
Hands-on GitLab CI/CD lab with synthetic pipelines |
robot-basics / robot-intermediate / robot-advanced |
Robot Framework training series — 1/3, 2/3, 3/3 |
cli-device-sim |
Network device CLI simulator for automation testing without real gear |
win-netlab-foundation |
Windows-first network automation lab — AD, DNS/DHCP, PowerShell baseline |
day0-boot-sim |
DHCP/TFTP provisioning simulator for day-zero device onboarding |
| Project | What it does |
|---|---|
git-clean-history |
Removes secrets across full git history — AWS, Azure, GCP, OpenAI, Stripe, GitHub |
repo-first-aid |
Audits public-repo trust signals before strangers find the problems |
repo-flight-deck |
Repo health dashboard: CI status, security alerts, PR risk scoring |
gh-sentinel |
GitHub activity monitor and alert CLI |
