Top SchoolJeffrey Penkar is a frontend engineer with 11 years of experience building user-focused web applications, currently leading signup and customer profile initiatives at Lee Enterprises. He specializes in JavaScript (vanilla, React, Redux), TypeScript, and Rails, and is actively transitioning legacy stacks (CoffeeScript, Rails views, Redux) toward modern React and TypeScript patterns. Previously at ShippingEasy and several startups he owned full-stack responsibilities—migrating technologies, stabilizing production systems, and improving test coverage and A/B experimentation.
