Projects, code, and systems work

Code that came from needing to understand the whole machine.

This page goes deeper than the resume: operating-system work, desktop experiments, harness engineering tools, automation platforms, and AI tooling that turned vague workflows into runnable software.

Public systems work.

RefugeOS and Valkyrie are the most personal examples: built to learn the stack end to end and to stop accepting limited options as a permanent constraint.

RefugeOS

A Linux/system project rooted in first-principles learning: understand the boot path, the desktop, services, package boundaries, and the practical tradeoffs that shape a usable environment.

  • Motivation: learn every step of how the system worked instead of treating the OS as a black box.
  • Motivation: build options when existing choices felt constrained or over-prescribed.
  • Signal: persistence through low-level system behavior, packaging, services, and real desktop ergonomics.

$ why RefugeOS?
> learn the whole stack
> reduce dependency on limited choices
> make the machine understandable
> build until the abstraction stops leaking

Valkyrie

Companion work around the Refuge ecosystem, focused on practical system interaction, desktop behavior, and the operator experience of making Linux feel intentional.

  • Explores how services, desktop controls, and workflow surfaces should cooperate.
  • Shows comfort debugging across boundaries instead of staying inside one framework.

Public Code Habit

The Codeberg/GitHub presence is not just portfolio decoration. It reflects a bias toward building visible artifacts, keeping momentum, and learning through implementation.

  • Codeberg is the primary home for Refuge-related work.
  • GitHub remains useful for broader experiments, utilities, and public profile discovery.

Engineering tools and automation.

These are the work-shaped projects: tools that make engineering comparisons, AI workflows, and infrastructure operations easier to run repeatedly.

DeltaManager

A harness comparison tool for analyzing engineering changes, compare reports, 3DXML parsing, and CATIA-assisted workflows.

  • Turns harness change comparison into a more inspectable workflow.
  • Combines domain-specific parsing with practical reporting and automation.
  • Fits the larger theme: reduce manual review friction and make engineering differences easier to reason about.

Aivato AI Tooling

Production code for AI-agent workflows: tool execution, guardrails, MCP integrations, RAG-backed retrieval, workflow helpers, and internal engineering tools.

  • Built around useful agent behavior instead of demo-only prompting.
  • Focused on safe tool use, retrieval, guardrails, and repeatable engineering workflows.
  • Includes practical product surfaces like compare reporting, QA, PDF-to-BOM, parts/cost data, lenses, exports, and wire tracing.

Ansible / AWX / AAP Workflows

Automation platform work around playbooks, roles, inventories, credentials, job templates, surveys, RBAC, workflow templates, and controlled self-service operations.

  • Designed for repeatable Linux operations and safer remediation.
  • Connects automation to monitoring, incident response, and operator workflows.

SRE Platform Tools

Automation frameworks, Vault-backed credential rotation, Oracle installation automation, AWS SFTP, containerized service migrations, and monitoring-triggered remediation.

  • Pattern: turn repeatable operational burden into controlled software.
  • Pattern: make the safe path the easy path for teams operating production systems.

Local product builds.

These are larger local projects from my workspace: developer tools, job-search automation, desktop applications, Android bridge work, and session/control-plane infrastructure.

Voodoo / valk-agent

A coding-agent runtime built around a controlled tool loop, workspace indexing, persistent task state, human review paths, and planner/executor routing.

  • Supports local OpenAI-compatible model routers such as llama-server, with optional planner/executor split.
  • Builds and reuses a lexical workspace index instead of dragging full transcripts forever.
  • Implements bounded tools, review queues, durable memory, stuck detection, orchestration, and an executor-owned plan loop.

Product and platform builds.

These projects show the other side of the work: practical business software, domain-specific engineering tools, and platform services that move from idea to usable workflow.

Odin CMDB

A Go-based configuration-management database with server, agent, and key-generation components for host inventory and tagged system metadata.

  • Agent collects host identity, hostname, memory, CPU count, OS/release data, and network interfaces.
  • Server exposes HTTP endpoints for registration, record updates, API keys, and plugin-backed storage.
  • Keygen utility provisions team API keys against the CMDB service.

HarnessStudio

A cross-platform harness engineering workbench built around a neutral harness model, migration adapters, validation, API surfaces, and an Avalonia desktop UI.

  • Moves beyond a converter by routing through core domain models, schema conformance, round-trip tests, and real sample fidelity.
  • Includes LDorado/XD migration work, schematic rendering, packaging, and pilot-release workflows.
  • Uses .NET/Avalonia to deliver the “newer WPF, but cross-platform” desktop experience.

VeriHome

An inspection-operations SaaS MVP for home inspection companies, focused first on booking, scheduling, availability, CRM/referrals, and admin operations.

  • Next.js, React, TypeScript, Tailwind, FullCalendar, Prisma, SQLite locally, and PostgreSQL deployment schema.
  • Public booking flow at `/book` and admin operations under `/admin`.
  • Stripe signup billing, email delivery, seeded data, and mock service boundaries for calendar, payment, notifications, travel time, and geocoding.

RapidRFQ

A local-first RFQ intake and estimator workspace for machine shops, built to accept STEP files and PDF drawings, analyze job readiness, and support quote workflow decisions.

  • .NET 8 Web API, React/Vite/TypeScript frontend, SQLite database, and local upload storage.
  • Estimator-focused RFQ inbox/detail workflow with local users, roles, audit trail, backups, and shop settings.
  • Backend tests cover quote math, STEP parsing, document extraction, supplier follow-up timing, portal tokens, similar-job scoring, and quote consolidation.
