Hello! I’m Isaiah Davis — a Frontend Developer and UI Engineer with deep experience building modern, accessible, and performant web products. I’ve worked across internal enterprise tooling and consumer-facing applications, always with a focus on measurable results.
At S&C Electric Company I led the modernization of three dashboards, cutting page load times by 72%, reducing asset weight by 41%, and achieving full WCAG 2.1 AA compliance across every updated view. That project is a template for how I approach all my work: audit first, architect thoughtfully, ship iteratively, document thoroughly.
I’m comfortable owning the full frontend stack — from design-token-driven CSS systems to CI/CD pipeline configuration — and I collaborate closely with designers, backend engineers, and stakeholders to deliver outcomes that matter to the business.
Currently: Open to new full-time, contract, and freelance opportunities. Chicago-based; remote-friendly.
