about

I’m Jeff, a Principal-level Front-End Engineer with 20+ years across fast-moving Philadelphia agencies and Vanguard, where I architected the framework-agnostic design system (AXS) that powers 11 product teams and the firm’s main advisor portal.

The agency years taught me speed; Vanguard taught me scale. The instincts compose. What I’m drawn to: durable abstractions, the design decisions that age well across platform shifts you didn’t see coming. The Vue-to-Web-Components approach I built years ago quietly became the foundation for generative-UI work nobody had imagined yet. Not luck.

I work player-coach style: I write code alongside the engineers I lead, pair-program through the hard parts, and stay close to the production codebase. Lately that means a lot of AI-assisted coding with Claude, including a two-month team refactor from Vue to Lit and a Gen UI prototype I built solo in two days.
