Engineering executive, lifelong learner and builder — VP of C2C & Seller Experience Engineering at eBay, founder of Cortexa LLC.
I've been shipping software since 1983: 6809 assembly on a TRS-80 Color Computer, Windows Kernel Streaming, Windows Media Center, Zune, Internet Explorer on Xbox 360, and today marketplace platforms at eBay scale. These days my personal engineering time goes into AI-native development — building the tools I wish every engineering team had.
What I'm building at Cortexa LLC
- ai-pack — a multi-agent development framework for Claude Code: agent roles, quality gates, and structured workflows (docs)
- mcp — Model Context Protocol servers in Go, including a federated project knowledge graph (KuzuDB, hybrid semantic search)
- xasm++ — production cross-assembler in modern C++20: 7 vintage CPU architectures, 5 classic syntax modes, 1,600+ tests, cross-platform CI with emulator boot validation — built end-to-end with ai-pack agent workflows
- sourcerer — modular disassembler for 6502, 6809, and Z80, companion to xasm++
- openphast — open-source bridge from 1990s Panja/AMX PHAST home automation to Home Assistant: reverse-engineered binary protocol over raw IPX (hand-built AF_PACKET framing), C++20 daemon, HA custom component, offline device simulator
- ADSync — a free macOS menu-bar app for Active Directory password sync (releases)
- Writing on AI-era engineering leadership and rebuilding apprenticeship for the AI age: LinkedIn
- 19 U.S. patents in streaming-media architecture and kernel-mode driver design
