Nathan Duffy is a Lead Web Developer with nine years of full-stack experience building and maintaining client-facing sites and internal tools from startups to enterprise teams. Based in Portsmouth, NH, he leads web projects at a small agency where he blends practical, budget-minded UX decisions with hands-on engineering across WordPress, Shopify, and custom stacks. His background includes enterprise-grade work at Fidelity—optimizing front-end performance, automating batch ETL processes, and modernizing legacy reporting systems—alongside freelance and contract roles that required network administration and cross-disciplinary problem solving. Known for a “sane engineering” approach, he focuses on pragmatic, maintainable solutions that minimize risk and operational overhead. He’s equally comfortable recommending business-impacting tradeoffs to clients as he is digging into server, database, or regex-level fixes behind the scenes.
