Full-stack engineer with 10 years shipping production software — and a rare habit of building and operating entire platforms solo: data model, tenant-safe RBAC, real-time, payments, cloud, and deploy. Google Cloud Professional Cloud Developer (2019). Built four production platforms in daily use by paying customers, spanning healthcare, manufacturing, marketing data, logistics, and CAD. EMT-turned-engineer who learns the business first, then ships the system that replaces the spreadsheets.

Selected projects

OH SCRAP!— Multi-tenant SaaS · Manufacturing ops

In production · my product

My product — built and owned by me, with Sutcliffe Mechanical as the flagship customer using it on the shop floor every day. Six versions shipped on a continuous customer-feedback loop, with tenant isolation ready for additional orgs.

Daily shop-floor use in production · 2+ yrs running a real shop · 6 versions shipped on customer feedback · 90+ tests passing

Solved The Problem— Platform engineering · Multi-tenant SaaS

Live · paying customers

A live platform at app.solvedtheproblem.com with paying customers and transaction revenue via Stripe Connect. New verticals now assemble from existing primitives instead of starting from scratch.

5 verticals on one platform · 32 reusable platform modules · 2+ yrs live in production

Sovereign Command Center— AI infrastructure · Full-stack platform

Operating daily · closed-source

Modern LLM tooling that never leaves the developer's machine — sold as a one-time license rather than a subscription. Demonstrates AI-era depth: multi-model orchestration, safety-gated code generation, and licensing, all built rather than bought.

6 safety gates on AI-written code · Local LLMs — cloud optional · 88 subsystem tests · 7 major subsystems

KAEB Sales System— Business operations platform

In production · maintained

A trusted, long-running engagement (~1.5 years of maintained production software). The schema-driven framework turns each new module into declarative config instead of bespoke code — proof of sustained reliability, not just a greenfield demo.

639 tests · zero failures · 1.5+ yrs continuous production · 6 handoff runbooks shipped

Experience

Webhead Solutions— Software Tailor · Full-Stack Engineer

Now

Fractional and project-based software for small, growing companies. A trusted ~1.5-year KAEB engagement anchors the work — alongside my own products: OH SCRAP, Solved The Problem, and Sovereign Command Center.

NexGen Solutions— Operations Manager / Dev Lead

Autodesk Gold Partner

Led development and operations: Autodesk Fusion 360 plugins, reporting data flows, and Salesforce admin/development. More GCP, more enterprise integration.

Winamac Coil & Spring— Software Developer

Indiana

A spring factory. Built shop-floor QA/QC tools and internal quoting systems — the manufacturing-ops DNA that later became OH SCRAP.

Colling Media— Developer

Arizona

A digital + traditional marketing agency. Built and maintained LeadFlow, stood up BigQuery datasets, and shipped recruiting software and tools for Knight-Swift Transportation. Worked daily in GCP — already Google Cloud certified.

Independent / agency work— Application Developer

Remote

Laravel 5.x business tools: quoting engines, technician management, logistics systems, and financial / wealth tools — asset allocators and more.

NewTek— Web Developer

Arizona

Built and maintained WordPress sites — then realized web apps paid better and solved harder problems, and went looking for them.

Emergency Department— EMT → self-taught developer

Phoenix, AZ

Running CPR, I watched nurses keep time on a paper towel. I went home, taught myself Java, and built an Android documentation app — CPR timer, med timer, IV access, airway. That was the start.

Certifications

Google Cloud — Professional Cloud Developer (2019)

Education

Glendale Community College — Web development coursework (2012–2016)

Building something durable? I occasionally join the right team as a founding engineer — say hello.
