Custom React Application Development

@vishal1145

Your routing logic will break if you're managing state across multiple components without a centralized store - I've debugged this exact pattern in 8 production React apps where page refreshes lost critical user data. Before jumping in, I need clarity on two things: What's your current state management approach (Context API, Redux, or component-level)? And are you hitting CORS issues with your API calls, or is authentication the blocker? Here's how I'll stabilize the codebase: - REACT + GITHUB: Audit your component tree to eliminate prop drilling and refactor class components to hooks where they're causing re-render loops. - NODE.JS API INTEGRATION: Implement axios interceptors with retry logic so network failures don't crash your dashboard - I've reduced API error rates by 70% using this pattern. - ROUTING + STATE: Fix memory leaks from unmounted components still holding subscriptions and add route guards to prevent unauthorized access. - RENDER DEPLOYMENT: Configure environment variables properly and add health check endpoints so you're not deploying broken builds to production. I've inherited 15+ messy codebases where the previous dev left no documentation. I don't rewrite everything - I fix what's broken, document what's confusing, and ship fast. Let's do a 15-minute screen share so I can see your repo structure and give you a realistic timeline.

Hi, As per my understanding: You need an experienced React developer to continue development inside an existing production codebase, focusing on frontend improvements, API integrations, debugging, routing/state fixes, and dashboard enhancements. The work requires someone comfortable navigating established GitHub structures, working quickly without disrupting production stability, and maintaining clean, scalable frontend architecture. Implementation approach: • Review the existing React architecture, GitHub workflow, and deployment structure on Render • Debug routing, rendering, and state-management issues across the application • Improve and extend frontend pages/components while preserving existing functionality • Integrate and validate backend API connections with proper error handling • Optimize dashboard workflows, responsiveness, and user experience • Test fixes thoroughly to avoid regressions in the production environment • Maintain clean commits, structured branching, and organized code standards • Collaborate efficiently within the existing development workflow A few quick questions: 1. Which state management solution is currently used (Context API, Redux, Zustand, etc.)? 2. Is the backend already stable or are API endpoints still evolving? 3. Do you have a staging environment separate from production on Render? 4. Are there priority bugs/features that need immediate attention first? 5. Is TypeScript involved or is the project fully JavaScript-based?

Hi there, I have read your project requirement, and you need an experienced React developer to continue work within an existing production codebase involving frontend updates, API integrations, dashboard improvements, and debugging tasks. I can help you with: • React frontend development and component updates • Routing, state management, and rendering issue fixes • Backend API integration and dashboard enhancements • GitHub workflow and existing codebase management • Debugging, testing, and performance improvements • Clean, maintainable, and production-ready frontend updates Quick questions: ============= Which state management solution is currently used (Redux, Context API, Zustand, etc.)? Is the backend already fully functional or are API modifications also required? Are there any urgent issues/features that should be prioritized first? Do you have staging and production environments set up on Render? Best Regards, Srashtasoft Team

I work on existing React/Node codebases regularly. Jumping into an active repo, finding what's broken, and fixing it cleanly is most of what I do. For this kind of work I usually start by reviewing the repo structure and understanding how the API layer connects to frontend state. That tells me where most bugs are hiding before I even open an issue. Relevant background: built and maintained dashboards and API-connected frontends on a trading platform (React, Node.js, PostgreSQL) and a long-running construction management system (Angular, Node.js). Both involved working deep inside existing codebases with real users. What's the current pain point: routing, state sync, or something else?
