Hi — I’ve read your brief and can stabilise and accelerate your MERN app while delivering the first wave of features. I’ll start with a focused audit (logs, Lighthouse, DB queries), fix functional bugs, optimise Node/Next server-side rendering and React bundles, tune MongoDB indexes/queries, and harden caching and concurrency. I’ll implement the scoped features from Figma/Jira, integrate the external APIs, submit a clean branch with tests, and provide a concise changelog and documentation for each endpoint. Do you provide CI credentials and a staging environment for tests? Which 2–3 features are highest priority for the initial sprint? Any strict uptime windows or maintenance blackout periods to avoid? Looking forward to hearing back from you and discussing this in the chat. https://www.freelancer.in/u/Rupal878 Rupal Saini

Hi there, I’d love to help you bring your MERN application back up to speed and ensure it’s robust for your next stage of growth. I have hands-on experience investigating and fixing complex bugs in production MERN stacks—identifying root causes and resolving slow-downs in both client and server layers. Optimizing performance to hit key Lighthouse metrics and ensuring smooth, reliable experience under load is familiar territory. Building scalable, well-structured new features in React (using hooks and context for maintainability), integrating APIs, and writing clean, reusable components is something I genuinely enjoy. I’m well-versed with GitFlow, webpack, and consistently follow best practices in code commenting and documentation. I’m ready to get started—let’s discuss your requirements and next steps! Best, Solomia

@camleniosoftware

Hello, I can stabilize and optimize your MERN application by resolving existing bugs, improving performance, and ensuring smooth client-server interactions. I will implement new features as scoped, integrate required REST/GraphQL APIs, and deliver clean, well-commented React components. All work will follow GitFlow, with proper pull requests, unit tests, and documentation. The goal is a fully functional, high-performing production app, ready for QA review and future feature expansion. Let's discuss further. Thanks!

@SashaDev1

Hi there, I'm excited to help stabilise and enhance your MERN application. I've worked extensively with production-grade MongoDB, Next, React, and Node.js systems, especially refining performance under heavy load and tracking down tricky bugs. My experience includes resolving complex functional issues, improving Lighthouse scores, and optimising both server and client code for a seamless user experience. I’m comfortable navigating existing codebases, working within modern GitFlow, and adhering to strict QA processes. Integrating REST or GraphQL APIs and building scalable, reusable React components (with hooks and context) is right in my wheelhouse. You can count on clean, well-documented code and thorough communication throughout. Looking forward to getting started and helping your product move forward with durable solutions and robust new features. Best regards, Oleksandr

@abhisyc70

I've spent 5 years building a PropTech platform from scratch, taking it from zero to a production system used by UK developers. Your performance issues likely stem from unoptimized MongoDB queries or state management bloat. I can trace and fix these systematically. Your situation needs someone who understands both immediate firefighting and long-term architecture. I've debugged production MERN apps under load, usually it's N+1 queries, missing indexes, or re-render cascades. I'll use React Profiler and MongoDB explain plans to pinpoint bottlenecks, then optimize without breaking existing functionality. For your new features, I follow clean component patterns with proper TypeScript interfaces and reusable hooks. You'll get pull requests with clear changelogs, not messy commits to main. I hold a 6.4/10 earning rating with a 5.0 star rating across 15 Freelancer.com projects. I deliver production-grade work that doesn't break. I'm available 40+ hours/week in IST timezone with daily progress updates. I can start immediately after the kick-off call and repository access. Happy to discuss your backlog and timeline today.

@agricha13

I’d love to jump in and get your MERN app back to feeling fast, stable, and future-ready. I’m used to joining existing codebases, digging through logs, profiling queries, and fixing the kind of hidden issues that only show up under real load. From MongoDB indexing to API bottlenecks to React render inefficiencies—I handle the full stack end-to-end. I can also pick up your Figma/Jira-scoped features, build clean modular components, integrate external REST/GraphQL APIs, and keep everything aligned with GitFlow and your CI requirements. Every change will be documented, tested, and delivered through a review-ready pull request. If you want someone who treats performance, clarity, and communication as non-negotiable, I’m ready when you are.
