Jan Szpila is a seasoned JavaScript engineer with 14 years of experience specializing in React and front-end architecture, currently building web apps at Experis. He has delivered production front-ends for a mix of high-scale consumer and enterprise products—from Amazon Prime messaging systems and The Washington Post to Caesars Sportsbook—bringing pragmatic full-stack experience when needed. Jan excels at modernizing legacy platforms and keeping feature parity across platforms, having shipped cross-device web clients and internal tooling at companies like Trov and Guaranteed Rate. Known for a dry sense of humor and a clear stance on JavaScript (not Java), he pairs strong implementation chops with a pragmatic, product-focused approach. Based in Chesterton, Indiana, he thrives on turning complex UX requirements into reliable, maintainable front-end systems. A long track record across startups and large teams suggests he’s as comfortable prototyping new features as he is stabilizing production at scale.
