Zentropy Labs: Work you can walk away from.

Systems engineering, AI evaluation, and technical operations

I turn ambiguous systems into inspectable tools, tests, and handoffs. My work spans model-neutral agent infrastructure, deterministic evaluation, developer tools, native and browser graphics, technical writing, client operations, and physical field work.

Available for paid work: full-time, contract, project, onsite, hybrid, or remote. Based in Seattle, Washington.

Three ways to work together

Path Where I fit Start here
Technical and evaluation Agent and model evaluation, developer infrastructure, systems integration, CI, security testing, technical support, and documentation. Engineering path
Public, union, and field Public service, ports, facilities, parks and grounds, arboriculture, client operations, scheduling, safety judgment, and physical work. Public-service and field path
Education and research Fellowships, labs, research operations, mentorship, continued learning, open-source work, and evidence-centered technical writing. Research and education

Evidence accepted upstream

These third-party results come before the owned product catalog because they show the work surviving another maintainer's scope, review, and repository.

  • AgentFence PR 261: an owner-approved and merged Go engine optimization with deterministic rule selection, allocation coverage, and green cross-platform checks.
  • Free Law Project PR 820: approved and merged documentation for running the fast DB-free test suite.
  • Mergewarden PR 107: replay fixtures for reusable-workflow pinning, revised after owner review, approved, merged, and CI-checked.

Capability constellation

Flywheel is the sole primary platform. The current verified release is Flywheel v0.3.10: one model-neutral workbench for routing, gated tool use, evaluation lanes, receipts, memory, context, and reproducible workflows. The rest of the workshop is organized as capability families, lanes, extensions, and bounded standalone systems rather than a fixed flagship count.

Family Representative public work
Agent systems Flywheel, Telos, Forum, Relay, Mneme
Evaluation and verification Terminal State Fixtures, Crucible, Emet
Security and privacy Phantom, authorized adversarial evaluation, privacy controls, and sanitized regression fixtures
Developer infrastructure BuildLang, Index, Plexus
Graphics and retro systems Studio Engine, Build Color, and the Retro Systems Lab
Research and education Gather, Learn, and publications

Phantom's boundary

Phantom v1.1.0 ships reversible hardware-identity privacy controls for Windows and Linux. It covers Layer 2 identity surfaces. Kernel and firmware layers are modeled but not shipped end to end. Use is limited to machines the operator owns or is expressly authorized to test.

Authorized security, kept bounded

Authorized security work spans adversarial AI evaluation, system hardening, privacy engineering, stress testing, regression fixtures, and coordinated reporting. The public surface contains sanitized tests, schemas, detectors, and bounded findings. Material that could enable misuse moves only through approved private or embargoed channels with a defined scope and remediation owner.

Retro Systems Lab

The lab follows play → preserve → verify while keeping each proof boundary clear:

  • Retro Engine is the interactive browser studio for owned pixel, palette, shader, and CRT experiments.
  • Engine Revival v0.1.0 is the public preservation and restoration-evidence spine.
  • BRender Archival v0.1.1 carries the specific BRender restoration record. Generic retro visuals are not presented as BRender evidence.

How I work

Map the real state. Reduce the uncertainty to an executable check. Build the missing surface. Record what the result proves and what it does not. Leave an artifact another person can run, inspect, maintain, or safely operate.
