Hire the Best React Bootstrap Freelancers
in India

I build high-converting Shopify stores and fast, modern web apps with React and Next.js. Whether you are selling products or launching one, I turn designs into clean, lightweight, conversion-focused frontends that scale. With 8+ years across Shopify, Shopify Plus, and modern JavaScript, I cover both sides of frontend: the ecommerce build and the app build. I focus on what actually moves the number, fast load times, mobile-first UX, clear product and checkout flows, and pixel-accurate builds straight from Figma or Adobe XD. What I do: Shopify & Shopify Plus: custom Liquid, theme architecture, app integrations, checkout customization, migrations React & Next.js: component-driven frontends, dashboards, SaaS interfaces, API integration, and server-side rendering for speed and SEO HTML, CSS & JavaScript: semantic, hand-coded, performance-first builds with Tailwind, Bootstrap, or SCSS Performance & CRO: Core Web Vitals, 90+ mobile scores, and UX built around the buying or signup decision Design to code is a core strength. I translate Figma, Adobe XD, or Photoshop into clean, fast, maintainable code your team can extend later, never heavy bloated marketplace themes. Working with me is simple: clear timelines, regular updates, and code that is easy to hand off. If you need a Shopify store that converts or a React or Next.js frontend that loads fast and looks sharp, send me your store URL or your designs and I will tell you exactly how I would approach it.
