@ihorz5

React Native Hi, there, I understand you need a React expert to complete your existing web app quickly, with web sockets experience being essential, to get it live without delays. The focus is on finishing the remaining features, optimizing real-time interactions, and ensuring smooth front-end performance. With strong experience in React.js, Node.js, web sockets, and frontend optimization, I can efficiently implement the remaining components, handle live data flows via sockets, and ensure the app is fully functional and responsive across all browsers. My work is clean, well-commented, and maintainable for future updates.

I am available to start right now and can work efficiently to meet your go-live timeline. Thanks, Ihor

@AliMhenterprise

React Native Hi, I hope you're doing well. I've built and shipped real-time web apps using WebSockets — live dashboards, chat systems, and data-sync features — so I know exactly what it takes to jump into an existing codebase and push it to production fast. From what you've described, you need someone who can audit the current state, identify what's left, and execute without hand-holding. That's exactly how I work. Quick question to get started — what's the current stack on the backend (Node, Laravel, etc.) and roughly what percentage of the build would you say is done? Best regards, Syed Muhammad Ali Farhan.

@ammarahmed20

"React Native" Thank you for considering my proposal for completing your web app project. Having spent over 6 years in the industry honing my skills, I am well-versed in React and its sibling, React Native, which is invaluable in your project. Not only can I expertly handle the existing codebase but I can build upon it quickly to ensure a speedy and efficient completion of your project so you can hit your go-live targets. Beyond React, my experience with web sockets is a key strength you're looking for. Engagements where I've leveraged web sockets have centered around building systems similar to yours - scalable, maintainable apps marked by a reliable, real-time communication layer. From a functionality perspective that means easy tracking updtes as multiple users still keep tabs on the same data; minimizing delays & easing the potential chaos of last-minute edits during deployments. To sum it up, my priority is delivering clean code that not only ticks all your necessary boxes but also aids long term stability and ease maintenance. Hiring me would mean hiring someone who works with transparency- early disclosures of approached limitations or misfit approaches; and eliminates unnecessary complexity. Click 'Hire Me' so we can get started together on taking your web app over the finish line!

⭐⭐⭐⭐⭐⸻ React Native Hi Finishing an existing React app quickly often gets blocked by unstable WebSocket connections, inconsistent state updates, and performance issues close to launch. I work on frontend systems and real time integrations. In a recent project, I fixed WebSocket driven updates in a React app where state mismatches caused UI glitches. After restructuring state handling and event flow, updates became stable and latency issues were reduced. For your app, I can jump in immediately, review the current implementation, and focus on stabilizing WebSocket communication, fixing remaining issues, and preparing the app for a clean launch. I also pay close attention to performance and edge cases that usually appear at this stage. I am available to start now and can move fast to help you go live. What issues are you currently facing with WebSocket behavior or UI updates? Is there a deadline for launch? I can review your code and proceed right away. Best regards, Sora
