I specialize in eLearning systems architecture and legacy system rescue — the projects where documentation is incomplete, vendors have departed, and the system is critical but fragile. Over 28 years, I've built SCORM/xAPI platforms, debugged multi-vendor integration nightmares, and applied NTSB investigative methodology to software forensics.
When conventional debugging fails, I bring the unconventional: Swiss cheese model failure analysis, SCORM API emulation for testing, and cross-domain middleware that shipped 5 years before commercial alternatives.
"If you want to cheat, cheat fair." — Moe Howard, Healthy, Wealthy and Dumb (1938)
Core technologies: JavaScript (Vue.js, React), HTML5/CSS3, WCAG 2.1 AA accessibility, cross-platform integration, forensic debugging, SCORM 1.2/2004, xAPI (Tin Can API), AICC, cmi5.
Approach: NTSB-style root cause analysis applied to software. When a system fails, I don't just fix the symptom — I map the contributing factors, analyze the Swiss cheese alignment, and recommend systemic improvements.
Vue.js wrapper with SCORM API emulation providing emulator save-state functionality for eLearning QA — save course state at any point, restore instantly, edit SCORM values directly, jump to any section. Reduced testing cycles from hours to minutes for gated content. Addresses a gap in commercial SCORM tools: reproducible debug states and session state inspection aren't first-class features anywhere else.
Cross-domain content delivery architecture built in 2011 — five years before Rustici released Content Controller to solve the same problem. Lightweight stub packages deployed to client LMS platforms; actual content served from central servers. Transparent SCORM/AICC protocol translation layer. Served ~20 energy utility clients drawing from a ~2,000 course library, 10+ years in production.
Investigated a 19% course incompletion rate (4x baseline) initially framed as a tracking bug. Multi-angle investigation revealed five concurrent systemic failures: memory cache vulnerability with no auto-save, a "Congratulations You Failed" UX pattern, confusing navigation, mobile workforce on poor WiFi, and short-burst usage conflicting with hour-long desktop design. Platform was eventually abandoned — indirect validation of findings.
Contributed to an existing React/GraphQL platform acting as a federated facade over Rustici Content Controller, PeopleFluent LMS, Watershed LRS, and Amazon Cognito. Primary work: large-scale multi-tenant rebranding navigating an undocumented Material UI theming system — scoped as one week, expanded to months as interrelated style dependencies emerged. Also: bug fixes, Cognito troubleshooting via log analysis, reverse-engineering Watershed LRS queries.
Open to opportunities in eLearning systems architecture, legacy platform rescue, or technical investigation roles. Especially interested in projects where the documentation is missing and the stakes are high.
