PROJECTS

What I build when nobody assigns it.

Platforms architected end to end — domain model, backend, frontend, integrations, infrastructure, and the operational tooling required to actually run them.

The career record is on Experience. This is the other half: what twenty years of that produces when the constraint is only time. Ventures I own outright are on Products.

PROJECTS.00

Four capabilities, one body of work.

Twenty years building software, then enterprise engineering, then architecture leadership — and now shipping complete products independently. The combination is the point; none of these four stands alone.

  • 01

    Product engineering

    Taking an idea from concept to production — including the operational tooling and admin surfaces that decide whether it can actually be run.

  • 02

    Systems architecture

    Designing domains, integrations, data flows, asynchronous workflows, and the boundaries that let a system keep changing after launch.

  • 03

    Frontend & UX engineering

    Deep frontend experience with formal UX training — enough of both to bridge engineering and product design rather than hand off between them.

  • 04

    Full-stack engineering

    Frontend, backend, database, integrations, infrastructure, and deployment. The whole path, which is why the projects below exist at all.

ERP Data Mapping Platform

Frontend architect · Full-stack engineer

Replaced a spreadsheet-driven ERP import workflow with a purpose-built application. Users had been hand-mapping XLS files into Sage Intacct; the new system let them upload, review, map fields visually, and run large imports asynchronously while continuing to work.

  • Held up when live volume exceeded the original scope by hundreds of thousands of records
  • Visual field mapping replacing manual spreadsheet mapping
  • Queue-backed import/export so large jobs never block a request
  • Frontend completion notifications for asynchronous work
  • Sage Intacct ERP integration
  • Laravel
  • Vue
  • TypeScript
  • SQL
  • Queues
  • Sage Intacct
  • REST APIs
  • XLS processing
Frontend Architecture at Organizational ScaleDelivered · Scorpion

Shared UI & Design System

Frontend architect

A shared component library and CSS foundation distributed over NPM and consumed by both React and Angular applications. Drew architectural cues from Tailwind, Bootstrap, IBM Carbon, and Ramsey's Gazelle — with accessibility built into the primitives rather than documented beside them.

  • 30–40% faster frontend development across adopting teams
  • Framework-agnostic CSS foundation consumed by React and Angular
  • Design tokens and reusable UI primitives
  • Accessibility as a property of the components, not a checklist
  • Contribution path so the system was not a central-team bottleneck
  • SCSS
  • Design tokens
  • NPM distribution
  • React
  • Angular
  • TypeScript
  • Accessibility

Aviation ↔ Sage Intacct Integration

Two systems of record disagreed about the same transactions. The durable fix was not a better sync job — it was deciding, field by field, which system owns what, and making disagreement visible instead of silent.

  • Laravel
  • Vue
  • SQL Server
  • Azure
  • Sage Intacct
  • Enterprise APIs
Enterprise Solutions ArchitectureCurrent · LIFE SURGE

LIFE SURGE Platform Systems

Solutions architecture across education, events, registration, payments, and internal platforms — setting system boundaries, integration patterns, API contracts, and AI strategy across multiple engineering teams alongside executive stakeholders.

Legacy Modernization · Frontend ArchitectureDelivered · Ramsey Solutions

E-Commerce Modernization

Modernizing legacy jQuery and Handlebars commerce surfaces toward React, across multiple brands and domains — with shared component patterns and the Gazelle design system holding consistency together.

  • React
  • Vue.js
  • JavaScript
  • TypeScript
  • Gazelle Design System
  • Accessibility

Labs

Smaller builds and experiments. Included because execution speed is its own signal, not because they are architecture.

  • Next Level Tutoring

    Rapid product execution · Shipped

    Idea to live business in roughly 96 hours — brand, site, funnel, payments, and marketing launch. Included here for the execution speed, not the engineering depth.

    • Next.js
    • Payments
    • Funnel
    • Analytics

  • Automation & Bots

    API-driven automation experiments · Ongoing

    A run of small event-driven automation projects across Discord, X, and game APIs — OAuth flows, scheduled jobs, and webhook plumbing. Where new integration patterns get tried before they show up in client work.

    • Node.js
    • Discord API
    • OAuth
    • Webhooks
    • Scheduled jobs
