Personal 3D CAD Application Research
Personal research project: a browser-based 3D CAD system where engineers author models in JavaScript with live preview. Exploring how mechanical design tooling can grow in this latest age.
Deeper write-ups, project summaries, and architecture diagrams — including NDA work for Microsoft, Echo Global Logistics, and Amazon — are collected on the AI / LLM / GenAI Work page.

Global postal-code validation and enrichment API covering 246 countries + territories (1M+ postal codes) at sub-5ms response. Built agent-native from day one — first-party Python, Node, and MCP SDKs, OpenAPI 3.0, and llms.txt for direct AI-agent consumption. Self-hosted Node 22 / Next.js 15 API surface with in-memory cache; Vercel for marketing, dashboard, OAuth, and Stripe webhooks; Neon PostgreSQL with Drizzle ORM. Transparent single-tier pricing at $0.000028/query. Founder & Owner. postaldatapi.com
Functional-mushroom coffee and cacao D2C brand based in Boise, Idaho. As Director of Technology and part owner, I own the full Next.js e-commerce stack on Vercel — Square (payments, orders, inventory), Shippo (real-time shipping), Resend (transactional email), and Printful (print-on-demand merch) — and advise on unit economics and channel strategy beyond engineering. fungaiacoffeeco.com
Partnering with the Microsoft Account-Based Marketing AI team on the analytics layer for Microsoft's account-based seller recommendation engine. Building reusable analytical infrastructure: Spark/PySpark notebooks against the recommendation-outcomes Delta lakehouse, a curated knowledge base of data snapshots and business references that compounds across sprints, and a self-contained Microsoft Fabric reporting tool that classifies free-text seller dispositions against a canonical taxonomy via Fabric AI Functions (gpt-4.1-mini) over millions of rows. Developed and documented a local-first / Fabric-validated working pattern to keep iteration speed high without sacrificing production rigor.
Founded and grew a worldwide mentoring community to 65K+ followers through technical and mentoring blog posts, bi-weekly tech chats where I helped data scientists work through detailed technical questions, frequent keynote talks, and ML book reviews for Packt. Starting data science communities inside the companies I've worked for is a pattern, not an accident.
Sales reps were receiving 30,000+ single-shipment quote requests per day via email — not managed accounts, so each request consumed sales-rep time for little profit. The software dev team was not available for front-end work, so I developed the full stack: an Outlook Add-In LLM-based AI Web App. Quote-request handling dropped from 5+ minutes to 15 seconds. Meaningful margin recovery for the company and compensation lift for the reps in the field.
ON Semiconductor's wafer-level vision test for digital-camera imaging die took 2+ person-weeks per tuning to identify subtle defects other tests missed. After tenured teammates said it couldn't be automated, I built it on my own time in the evenings. Three months later: x/y pixel positions as features, grayscale values as labels, 5th-order feature engineering for a fit that wasn't overfit, statistical-band clustering for pass/fail. The application graded better than I did manually.
Texas A&M University, August 1997. Multi-physics modeling and design methodologies for hybrid vehicle power plants using bond-graph methods. Modular component models (engines, induction motors, batteries, thermal-fluid subsystems), series / parallel / complex hybrid architecture exploration, and critical-design-parameter identification.

Texas A&M University, May 1995. A robot calibration methodology that avoids matrix scaling by restructuring the calibration equations to produce well-conditioned matrices from the start. Validated with simulated data and real-robot measurements. Three peer-reviewed IEEE publications followed. Calibration work also fed NASA experiments for Space Shuttle Robot Arm operations. Advisor: Dr. Louis J. Everett. Download PDF · Read summary
