  • SAVVI Financial2022–2026

    Rebuilding a benefits platform used by millions of employees

    SAVVI’s AI-powered platform helps employees and their families make informed benefits decisions, and grew from tens of thousands to millions of employees while I was there. As the first in-house frontend engineer, I moved the app from React Native to a standard React web app with semantic HTML. Load times dropped by more than half, the bundle shrank by over 50%, Lighthouse scores rose from under 40 to over 90, and the platform reached full WCAG 2.1 AA compliance. I also partnered with the CTO on rollouts through Voya, Benefitfocus, and PlanSource.

  • ExpoLife at U.VU2022–Present

    Making health data explorable on a map

    ExpoLife, now in beta, is a health-analytics platform that connects environmental exposures with health outcomes. As part of the founding team and sole frontend engineer, I built the experience that turns a plain-language question into an interactive map, neighborhood-level overlays, and rankings, with a streaming AI chat and analytics working as one product. Built with React, MapLibre, D3, React Query, and Material UI.

    A digital collectibles marketplace on Solana

    Led frontend development of a marketplace for minting, buying, and reselling digital collectibles, including a planned Bob Dylan collection developed with the artist’s management. The project was shelved when the NFT market collapsed in 2022.

    A spreadsheet-style web app for enterprise packaging design

    Senior frontend engineer for a SaaS platform that takes product packaging from creative brief to production-ready artwork, used by Dunkin’, Welch’s, Home Depot, Duracell, and Scotts. Built its next-generation web spreadsheet, with full data management, custom forms, validation, and reporting, and worked on the replatform of its legacy application.

  • PixelMEDIA2005–2012

    Ecommerce sites for national brands

    The developer sent in wherever large client projects needed help, picking up each account’s stack on the fly. Built Demandware storefronts for brands like Perry Ellis, Pier 1 Imports, Rubik’s, ECCO, and Samuel Adams, and contributed responsive design, SEO, and structured data to Demandware’s SiteGenesis 2.0 storefront.

How I help

What I bring to a team

I’m looking for a senior full-time frontend role on a product team that needs someone to own the frontend, whether that means untangling an existing app, improving a critical workflow, or building something new. I also take on select contract work.

  1. Modernize an existing application

    Move an aging frontend onto a modern, maintainable foundation, like the SAVVI rebuild that cut load times in half, so your team can ship safely and keep improving.

  2. Build a data-rich web product

    Maps, charts, spreadsheets, and detailed forms that help people understand their data and act on it without getting lost.

  3. Improve performance and accessibility

    Find what’s slowing users down or shutting people out, then fix it with measurable results, from faster load times to full WCAG 2.1 AA compliance.

  4. Own the frontend

    Someone who takes ownership of the hard parts, not just tickets, and works directly with product, design, and engineering leadership.

Getting started: a short conversation about your team and product, then a clear take on where I can help.

About

Easy to work with, serious about the work

I started out building websites for local businesses, spent about ten years doing full-stack WordPress, Drupal, and PHP work, then focused on frontend development and UI/UX. Most of my career has been on small teams, often as the only UI developer, so I’m used to owning a product’s frontend from design handoff to production.

AI is part of both what I build and how I build it. I built ExpoLife’s streaming AI chat interface and worked on SAVVI’s AI-powered benefits recommendations. Day to day, I use AI coding agents in Cursor, with models including Grok, Fable, and Gemini, to explore approaches, write and review code, and generate tests. It lets me move faster and check more of my own work. The judgment calls, like architecture, accessibility, and what’s right for the people using the product, are still mine.

I try to keep things fun and easygoing, even when the work is hard, and many of my colleagues have become good friends. Outside of work, I’m a dad of three and have been playing guitar for more than 30 years.
