I will fix bugs and optimize your react or next js app
Hameedurrehman
About this gig
Is your React or Next.js application running slow, dropping frames, or frustrating users with persistent bugs? A sluggish app directly impacts conversion rates and user retention. I deliver root-cause solutions to speed up your web application and fix state, render, and routing issues.
With proven, real-world results including a 25% decrease in page load times, a 20% reduction in system runtime, and 50% fewer state-related bugs using modern toolkits, focus on long-term performance fixes rather than quick patches.
What I Offer
- Performance Optimization: Eliminate unnecessary re-renders, optimize images, implement effective memoization (useMemo, useCallback), and code-split heavy bundles.
- State Management & Bug Fixes: Resolve complex Redux Toolkit, Context API, or prop-drilling bugs to keep data flow predictable and clean.
- Next.js Enhancements: Optimize Server-Side Rendering (SSR), Static Site Generation (SSG), App Router/Pages Router architecture, and API routes.
- Performance Audits: Diagnostic reporting using React DevTools Profiler and Lighthouse metrics to locate exact bottlenecks.

FAQ
What do you need from me to get started?
I’ll need temporary access to your repository (GitHub/GitLab/Bitbucket) or source code, a brief description of the bug or slowness, and details on where the issue is reproducible (e.g., specific browser, device, or route).
Can you fix issues in both the App Router and Pages Router in Next.js?
Yes. I have extensive experience optimizing and bug-fixing both Next.js App Router and Pages Router architectures, including SSR, SSG, ISR, and server actions/API routes.
How do you measure performance improvements?
I use standardized profiling tools—including Chrome Lighthouse and React DevTools Profiler—to capture benchmark metrics before making changes. I re-test after optimization to provide clear, quantifiable before-and-after proof.
What if my app uses custom state management instead of Redux?
No problem. While I specialize in Redux Toolkit, I also work extensively with React Context API, Zustand, MobX, Recoil, and standard useReducer/useState setups to resolve data flow and re-rendering bottlenecks.
Will your changes break any existing features?
No. I focus on root-cause refactoring and test all code locally before delivering. If your repository includes automated test suites (Jest, Cypress, React Testing Library), I ensure all existing tests pass before submitting the final work.
