Senior Front-End Engineer · React · Next.js · TypeScript · Automation · AI Workflows · Accessibility
I’m a Senior Front-End Engineer with 15+ years of experience building scalable, high-performance web applications. My focus is on accessible, maintainable, and automation-ready interfaces built with React, Next.js, and TypeScript.
I design front-end systems that perform under pressure and scale smoothly—from component structure and CI/CD pipelines to end-to-end testing with Playwright. I care about developer experience as much as user experience: clean processes, predictable builds, and friction-free releases.
- CI/CD pipelines with GitHub Actions and Vercel
- Automated testing with Playwright and Jest
- Monorepo management with Turborepo
- AI-assisted development using Cursor, Copilot, and Windsurf to standardize repetitive work and accelerate delivery
- Modern accessibility and performance tuning practices (Lighthouse / Core Web Vitals)
- Portfolio – johnschibelli.dev Personal site built with Next.js 15 and TypeScript; dynamic content via Hashnode / Contentful; automated deploys to Vercel.
- IntraWeb Technologies Company site and incubator projects using CI/CD, Playwright, and accessibility-first design.
Freelance or consulting work focused on:
