I build scalable Angular and Node.js applications, including real-time AI assistants and enterprise commerce platforms.

I've rebuilt Eaton's Digital Assistant in Angular and TypeScript, reducing first visible AI response text from 43 seconds to about 2 seconds through Server-Sent Events and RxJS streaming. I designed its authenticated real-time architecture, integrated roughly nine REST endpoints, and delivered product, service-order, and project-search capabilities for enterprise teams and customers.

Across 14+ years, I've delivered 13+ e-commerce, fintech, and healthcare projects, including five SAP Commerce storefronts for the Hering group. I've also built Tableau extensions, Python data pipelines, Laravel backend features, and high-volume MySQL optimizations while working in fully distributed English-speaking teams.
