01 / SELECTED WORK

Built to be inspected.

Five projects spanning applied AI, product engineering, native development, infrastructure, and clean-room research—with public source where safe and concrete evidence where systems must stay private.

01PRIVATE CASE STUDY

Galileo-AI

Sep 2026—present · Project owner · System designer · AI-assisted developer

I designed and built a private, self-hosted AI development platform that connects local language models to coding tools, persistent project context, hybrid documentation retrieval, scheduled workflows, and evidence-based verification.

Built with
Python · TypeScript · Ollama · SQLite · ONNX · Docker
Engineering focus
Reliable tool use, bounded recovery, approval gates, and shared-GPU operation

Private source by design. Architecture and dated results are shown without exposing code, credentials, personal data, or internal access.

02LIVE WEB APP

BeatFlight

A music-reactive, one-button browser rhythm game where every track shapes the timing, visuals, and challenge of the run. Local audio analysis stays in the browser.

Built with
Next.js · TypeScript · Canvas · Web Audio API

03INTERACTIVE SAMPLER

QuickCalc

A compact native calculator for macOS, Windows, and Linux, built with modern C#, .NET 10, and Avalonia 12. The sampler reproduces the public desktop interaction model in-browser.

  • Chained operations and repeated equals
  • Mouse and full keyboard controls
  • Calculation engine separated from the UI

04SAFE DATA DEMO

PiRouter

A touch-first Raspberry Pi 5 console for network health, Time Machine storage, encrypted Restic archives, Tailscale, service endpoints, and system telemetry.

The production console stays private by design. This guided preview uses synthetic values and exposes no home-network data.

05RESEARCH DOSSIER

DisplayLink clean-room research

Original macOS research for a Plugable USB display dock: read-only hardware discovery, bounded structural parsers, synthetic transport models, and a deliberately gated state machine.

This is not presented as a finished display driver. The public record separates observed facts from hypotheses and stops before undocumented hardware writes.

02 / SELECTED IMPACT

Proof in production.

The strongest engineering work connects technical decisions to outcomes people can see, use, and measure.

01
WORKFORCE SYSTEMS

Replaced a six-figure licensing dependency.

Built a proprietary employee badging platform with secure scan workflows and Apple Wallet and Google Wallet support—saving more than $100,000 annually.

React NativeNext.jsSecure workflows
02
OPERATIONS AT SCALE

Turned physical inventory into protected data.

Designed digitization tools, led cross-team adoption, and established reusable standards that cataloged over $2 million in project inventory and cut asset loss by 90%.

Product discoveryPlatform designChange leadership
03
CLOUD ENGINEERING

Moved critical workloads to on-demand infrastructure.

Developed and operated 15+ AWS Lambda functions and supporting services, replacing outsourced work and reducing always-on EC2 usage to avoid seven-figure projected costs.

AWS LambdaNode.jsFastAPI
03 / EXPERIENCE

Built across the stack.

Four-plus years of professional engineering experience, grounded in an earlier career of customer service and operational ownership.

MAY 2024 — PRESENT

Full-Stack Software Engineer & IT Manager

Armstrong Construction GroupScottsdale, AZ

Leading the complete lifecycle of internal products—from operational discovery and architecture to deployment, adoption, and support.

  • Built production applications spanning employee identity, time tracking, intelligent document retrieval, and inventory operations.
  • Migrated physical records into OneDrive and developed an AI-assisted Next.js search experience using Radix UI, Tailwind CSS, and Prisma.
  • Created a secure multi-user QuickBooks Enterprise environment with local virtual machines and Tailscale for remote accounting collaboration.
  • Standardized IT operations with automated Windows deployment, Microsoft 365 conference rooms, and hands-on endpoint and account support.
FEB 2022 — JAN 2024

Full-Stack Software Engineer

FarmFlightTempe, AZ

Built and operated data-intensive product capabilities, APIs, background workers, and cloud services for an agricultural technology platform.

  • Designed and maintained a 300+ table Amazon RDS PostgreSQL environment supporting evolving product data models.
  • Built Node.js and FastAPI services that managed first- and third-party licensing workflows and handled thousands of requests per day.
  • Added telemetry and detailed logging to connect API behavior with vector context for faster diagnosis and better system insight.
  • Worked across CI/CD, code review, load testing, and unit, integration, and end-to-end automation while owning daily-use customer features.

05 / FOUNDATION

Technical instincts. Operational empathy.

Before writing software professionally, I worked directly with customers, devices, inventory, and high-pressure operations at Best Buy, Staples, Walmart, and Subway. That experience still shapes how I build: understand the real workflow, explain the tradeoffs clearly, and make the system dependable for the people using it.
