Expert React.js developer in Pune building modern, interactive web applications with pixel-perfect UI, component-based architecture, and performance-optimized code for scalable business solutions.
Let's discuss your project requirements. I'll provide a detailed proposal with timeline and transparent pricing.
I build React.js applications that are fast, interactive, and built to scale. Not just functional apps - I'm talking smooth user experiences with sub-2-second load times, pixel-perfect interfaces, and component architectures that make adding features easy instead of painful.
I've delivered 50+ React.js projects across Pune and beyond - from dashboards to SaaS platforms to e-commerce sites. Recently built a real-time analytics dashboard for a Pune-based fintech startup using React 18 with optimized re-renders that handles 10,000+ data points without lag. Their users love how responsive it feels compared to their old jQuery-based system.
Here's what makes my React.js development different: I don't just build components - I architect systems. Proper state management so your app doesn't become a tangled mess. Clean component structure that any developer can understand. Performance optimization from day one - lazy loading, code splitting, memoization. And TypeScript throughout for type safety and better developer experience.
I've been specializing in React.js since 2018 - that's 6+ years working with everything from React 16 through React 18's latest features. I know hooks inside out, understand when to use Context vs Redux vs Zustand, and can implement complex UIs that remain maintainable as they grow.
Every project gets pixel-perfect implementation from your designs, performance-optimized rendering (no unnecessary re-renders wasting CPU cycles), reusable component libraries that speed up future development, and those polished interactions (loading states, optimistic updates, smooth animations) that make users think "this feels professional."
You're not getting someone who just knows React syntax. You're getting expertise in building production-grade applications that handle real user loads, scale as your business grows, and remain maintainable over time. That's the difference between code that works and code that works well.
I start by understanding your application needs, user workflows, and technical requirements. We discuss features, data flow, third-party integrations, and performance goals. I analyze whether React is the right choice (it usually is) or if Next.js would be better for SEO needs. This takes 2-3 days and results in a technical architecture document with component hierarchy, state management approach, and development timeline.
I set up the React project with TypeScript, configure build tools (Vite or Webpack), establish folder structure, set up linting and formatting rules, and create the base component architecture. This includes configuring Tailwind CSS or your styling solution, setting up state management, establishing routing, and creating development workflows with Git.
This is where I build your React application component by component. I implement designs pixel-perfect from Figma, create reusable components with proper props and TypeScript types, handle different states (loading, error, success), add animations and transitions, and ensure responsive behavior. You see progress regularly through staging deployments.
I implement proper state management patterns, connect to your APIs or backend services, set up data fetching with caching strategies, handle authentication and authorization, implement real-time features if needed, and ensure proper error handling throughout. Everything is built with TypeScript types for both components and API responses.
Before launch, I optimize everything. Code splitting and lazy loading for faster initial loads, bundle analysis to reduce size, implementing React.memo and useMemo where needed, optimizing images and assets, and ensuring smooth rendering even with complex interactions. I test across browsers and devices, verify accessibility, and run Lighthouse audits.
I deploy to Vercel, Netlify, or your preferred platform, set up CI/CD pipelines for automated deployments, configure environment variables properly, implement error tracking with Sentry, and provide comprehensive documentation. Your team gets clear docs on component usage, state patterns, and how to extend the application.
React.js projects typically range from ₹80,000 to ₹4,00,000+ depending on complexity. Simple dashboards or admin panels: ₹80,000-₹1,50,000. Mid-complexity web applications with API integration: ₹1,50,000-₹2,50,000. Complex SaaS platforms with real-time features and extensive functionality: ₹2,50,000-₹4,00,000+. I provide detailed quotes after understanding your specific requirements, features, and timeline. This includes development, testing, optimization, and deployment.
Most React projects take 4-10 weeks from kickoff to launch. Simple applications with basic features: 4-5 weeks. Medium-complexity apps with multiple views and API integration: 6-7 weeks. Complex platforms with extensive features: 8-10+ weeks. Timeline depends on feature complexity, number of views/components, integration requirements, and design intricacy. I'll provide a detailed timeline with milestones after reviewing your requirements.
React is a library for building user interfaces - you structure everything yourself. Next.js is a framework built on React that adds server-side rendering, file-based routing, and optimization out of the box. For dashboards, admin panels, or apps where SEO doesn't matter, pure React works great. For marketing sites, blogs, or SEO-dependent applications, Next.js is better. I'll recommend the right tool based on your specific needs.
Yes, I handle migrations regularly. We can either rebuild from scratch with React (better for complete modernization) or gradually migrate section by section (less risky for large apps). I've migrated jQuery, Angular, and vanilla JavaScript apps to React. The process involves rebuilding functionality in React components, setting up proper state management, and ensuring feature parity. Most migrations take 6-10 weeks depending on app size.
Absolutely. Every React app I build is fully responsive and mobile-optimized. React itself is platform-agnostic - it works anywhere JavaScript runs. I design and test specifically for mobile, implement touch-friendly interactions, and ensure fast performance even on slower devices. If you later want native mobile apps, React knowledge transfers to React Native.
Through multiple optimization techniques: code splitting to load only needed code, lazy loading for routes and components, React.memo to prevent unnecessary re-renders, useMemo and useCallback for expensive computations, virtual scrolling for large lists, optimized bundle sizes through tree shaking, and proper React Query caching. Target is always 90+ Lighthouse scores.
I strongly recommend and use TypeScript for all React projects. TypeScript catches bugs during development instead of production, improves code quality, makes refactoring safer, and provides better IDE autocomplete. The upfront investment pays off massively in fewer bugs and easier maintenance. However, if you have specific reasons to use JavaScript, I can accommodate that.
Yes, I integrate React apps with any backend - REST APIs, GraphQL, Firebase, Supabase, custom Node.js servers, Django, Laravel, whatever you have. I implement proper data fetching, authentication, error handling, and real-time updates if needed. I work closely with backend teams or can connect to existing APIs with documentation.
Every project includes one week of post-launch support for adjustments and bug fixes. After that, you can opt for monthly retainer support (starting at ₹20,000/month) or reach out when needed. Because I write clean, TypeScript-based code with good documentation, you can also bring in other React developers - they'll be able to understand and extend the codebase easily.
Yes, I implement real-time features regularly using WebSockets, Server-Sent Events, or Firebase Realtime Database. I've built chat applications, live dashboards with updating metrics, collaborative tools, and real-time notifications. React handles real-time updates efficiently when implemented correctly with proper state management and optimization.
Yes. Every project includes comprehensive documentation covering component usage, state management patterns, folder structure, API integration details, environment setup, and how to add new features. I also document complex logic inline and use TypeScript types as living documentation. The goal is to make the codebase accessible for whoever works on it next.
Because I've been building production React apps for 6+ years with 50+ completed projects and proven results. You're not getting someone learning React on your project - you're getting expertise in modern patterns, performance optimization, and scalable architecture. I deliver clean code, meet deadlines, communicate clearly, and build applications that perform. Being in Pune means we can meet in person when helpful, though I work effectively remotely too.
