A Human Business Academy Platform

A multi-tenant learning and certification platform for a business selling an online course, a live seminar, and an annual company-wide certification. Sole engineer, architect and content designer. All 355 commits are mine.

• Cloudflare Workers
• D1
• KV
• Wrangler
• GoHighLevel
• Magic-link auth
• Multi-tenant

• Auth is magic links over signed session cookies, and access is per-person grants rather than shared room codes. A code routes you to your tenant. It is never the credential.
• Entitlement has exactly one source of truth and everything else is a cache. Access sync fails open by design, and a nightly reconciliation job catches the webhooks that never arrived.
• I wrote the constitution and the data schema before the code. Ten laws, including one that has cost me features: an employer can see that an employee completed a lesson and can never see what they wrote in it. That floor is enforced at the store on read, not per view, so a private entry cannot leak into a roll-up, a search, or an export.
• The legacy KV stores became one D1 table. All 32 existing records were backfilled and verified against a pre-migration baseline before the originals were retired.
• One deploy script, and nothing reaches production around it. The team works inside the same Worker I am shipping to, so a careless deploy does not break a side project. It breaks the room somebody is mid-sentence in.

Gemba & Kaizen: public course and journal

A seven-lesson public course teaching a continuous-improvement method, with an interactive journal and printable forms. I shot it, cut it, and built it.

• Static HTML/CSS/JS
• Cloudflare Pages
• Vimeo
• Local persistence
• Print stylesheets

• Learners commit to an action before each video and report back after: it worked, it flopped, or they never got to it. Flops are the most useful answer, so the interface offers that as a real choice instead of a failure state.
• That loop paces the course, which let me delete the thirty-day time lock the original design depended on. Entries persist in the browser and print cleanly.
• Filmed on the manufacturing floor of the business it describes, so the examples are the company's own, not stock scenarios.

Bryn Athyn Cemetery Finder

A public app that helps people find a specific grave and walk to it. One codebase shipping to web and native. All 318 commits are mine.

• TypeScript
• React Native
• Expo
• Three.js
• React Three Fiber
• Leaflet
• Firestore
• Vitest
• Playwright
• Photogrammetry

• The hard part was never the map. Roughly 1,400 burials exist across five sources that disagree with each other: GPS coordinates scraped over several days with drift, the cemetery's own spreadsheet where lot number and person are conflated, an archival topographic map, scanned plot drawings, and my own drone survey.
• 50 test files across Vitest and Playwright, plus guards written for this project's specific failure modes: offline map packs because the site has no cell service, a bundle-size budget, an automated design audit, and a parity test that stops the web and native maps drifting apart.
• 3D walkthrough and 2D map share one data layer, so a record can never appear in one view and not the other.
• Next: a drone orthomosaic for true positions, using already-verified graves as control points rather than buying survey hardware.

Elevator Academy: installer training for a global manufacturer

Installation training for elevator interiors, built for delivery into a global elevator manufacturer's enterprise learning environment.

• SCORM
• Workday LMS
• Offline PWA
• Instructional design

• Shipped as a fully self-contained SCORM package with no outbound calls, on purpose. It clears enterprise security review without a data-processor agreement, because it holds no employee data and phones nowhere. When content changes, they get a new package.
• Paired with an offline-capable PWA for the job site, where there is no reliable connectivity and no appetite for logging into a corporate LMS on a ladder. Installers cache the module they need over WiFi first.
• Designed as step-by-step guides that check off as you go rather than as a quiz-and-certificate compliance artifact, because the goal is that the panel goes in correctly.

Silver Park Studio: film, stills and this site

Brand films, promos and documentary work for AT&T, CBRE, Compass, Ryder and Sobeys, alongside the stills. The studio's own WordPress, WPBakery and shared-hosting stack replaced with hand-written static HTML on Cloudflare Pages.

• Showreel 1:22
• The Heart of the Pennypack 4:41
• Sobeys × Worklete 1:50
• AT&T Testimonial 1:04
• Manor College 2:33
• Compass Tampa 1:03

• Cloudflare Pages
• Pages Functions
• Zero dependencies
• WebP

• No framework, no build step, no dependencies. A Cloudflare Pages Function replaced Contact Form 7 and Akismet.
• Self-hosted fonts, responsive WebP with JPEG fallbacks, structured data, and 301s preserving every old media URL, because the résumé path was already live in submitted job applications.
• Hosting cost went from about $300 a year to zero.
