I need an experienced [login to view URL] engineer who can dive straight into live, customer-facing applications and make them faster, leaner, and more reliable. The stack you will touch is almost entirely front-end; our backend services are already in place, so your day-to-day focus stays inside the [login to view URL] layer—React components, API routes, SSR logic, and the build pipeline. What the first weeks look like • Audit the current codebase, Lighthouse scores, bundle sizes, and server-side rendering path • Prioritise quick wins, then implement deeper refactors that cut load times, improve Core Web Vitals, and harden caching strategies • Document every meaningful change so the rest of the team can follow your optimisations Work cadence • 100 % remote but you must overlap New York hours: 6 AM – 3 PM EST, Monday–Friday • Start immediately; we want to see the first measurable performance gains within days, not weeks Why this is worth your time You’ll join a long-term, growth-oriented environment where high-impact work is the norm. As soon as you demonstrate results, we open up larger features and architectural ownership to you. If you have a proven record of squeezing every millisecond out of [login to view URL] apps and can work independently against clear deadlines, let’s get started.

This is exactly the kind of role where I can add value fast. You already have the backend in place, so the real impact comes from tightening the Next js layer and that is where I work best. I can jump into a live app, audit Lighthouse scores, bundle size, SSR paths, caching, image delivery, and render behavior, then turn that into quick performance wins within the first few days. After that I focus on deeper refactors that improve Core Web Vitals, reduce JS weight, prevent unnecessary rerenders, and make the app more stable under real user traffic. I have worked on performance focused React and Next js projects where the goal was not just cleaner code but measurable gains in load time, SEO signals, and user experience. I also document each important change clearly so your team can track what was done and why it improved the app. I can work independently, move fast, and overlap with New York hours as required. Your need for someone who can enter a customer facing product without a long ramp up is exactly how I prefer to work. Let me step in, find the biggest bottlenecks, and start improving the app right away. Please send access to the repo, current deployment setup, and any recent Lighthouse or analytics reports from your side.

Hi, I reviewed your project requirements and I can help you with this. I recently worked on a similar project where I developed a responsive website with custom functionality and optimized performance for a better user experience. For your project, I can handle the development, implement the required features, and ensure the website/app is scalable, secure, and fully responsive across devices. My experience includes WordPress customization, Shopify development, MERN stack applications, and React/Node based solutions, so I’m confident I can deliver exactly what you need. A couple of quick questions: 1) Do you already have the design ready, or should I create it? 2) Are there any specific integrations or features you want to prioritize? If you’d like, I can also share relevant work examples and discuss the project in more detail. Looking forward to hearing from you. Best regards, Tejash J
