**This is the hands-on side.** Every item is something I have built, run or repaired,
with the page that shows the evidence.

### Storage and servers

 * TrueNAS SCALE and ZFS across multiple pools, with a single-disk-pool risk map.
 * Rebuilding a failed five-drive NAS by hand and checking every share against its“
   already migrated” copy.
 * Diagnosing a boot-loop crash from console photos, cancelling an unnecessary reformat
   and salvaging the unique data.
 * Evacuating a failing drive (118,599 files, 1.52 TB) with every count, byte and
   date verified.
 * Working with awkward older gear, including a forgotten NAS with one weak core.
   See [hardware limits](https://jcody.com/ai-projects/hardware-limits/).

### Networking and security

 * UniFi networks, cameras and door access.
 * One front door for public access: a single forwarded port pair into a hostname-
   routed reverse proxy, instead of per-server forwards.
 * Read-only mounts, least privilege and logged approvals.
 * Finding the real bottleneck by measurement: a 1 gigabit mini-PC throttled a 10
   gigabit server to about 8% of its link.

### Data and databases

 * A Postgres inventory of every file: sha256, md5, quick hash and a media probe,
   written in real time.
 * Three quality gates per volume: counts match, every file hashed, a random independent
   re-hash agrees.
 * Deduplication, golden-record selection and parent-to-child lineage.
 * pgvector groundwork for search by meaning. See [the six AI skill areas](https://jcody.com/ai-projects/six-ai-skill-areas/).

### Video and media

 * A decade or more of video and drone production.
 * GPU HEVC encoding with VMAF quality scoring and triage rules.
 * Metadata care: 360 degree flags, GPS and telemetry tracks, spatial audio and 
   original timestamps. See [the two nights](https://jcody.com/ai-projects/the-two-nights/).
 * Premiere and Media Encoder workflows.

### AI operations

 * A manager agent and two worker agents, with job cards and check-backs.
 * A five-level risk ladder that decides what AI does alone and what a human must
   run. See [guardrails](https://jcody.com/ai-projects/guardrails/).
 * Orchestration in plain scripts that use no model tokens.
 * Knowing when not to train a model on messy data.

### Marketing and sales engineering

 * Decades of positioning, messaging and customer storytelling.
 * Demos, events and testimonials, and the data behind them.
 * Turning technical proof into something a buyer can act on.
