You will get Fix bugs in React JS | Next JS | Website bug fixing
Project details
Bug fixing isn’t just about “making errors disappear” — it’s about restoring speed, stability, and user trust.
This project delivers professional bug fixing and UI fixes for React JS, Next.js, and React Native applications, targeting the issues that actually hurt your product: broken flows, slow screens, layout glitches, crashes, and unpredictable behavior across devices or browsers. The focus is not quick patches, but clean, reliable fixes that don’t create new problems later.
What you get:
Accurate bug identification (logic, state, rendering, API, performance)
UI & layout fixes that work across screen sizes and platforms
React JS crash & performance fixes
Next.js hydration, SSR, routing & SEO-related bug fixes
Clean, tested fixes without breaking existing features
Ideal if your app is live, users are complaining, or things “mostly work but feel off”.
If you want bugs fixed properly, fast, and without rework, this is built for you.

React Native Expert Needed to Fix Socket Connection After Server Migration
Munib is an excellent communicator and very detail-oriented. He quickly identified and resolved complex socket issues that were blocking progress and was consistently available throughout the task. Reliable, efficient, and easy to work with — I’d happily recommend him and work with him again.

Require A Senior React Native Developer
He was extremely responsive and quickly fixed multiple React Native bugs. The app became noticeably more stable, and the overall experience working with him was smooth and professional. He even optimized overall performance somehow, do not know how

💼 𝗔𝗯𝗼𝘂𝘁 𝗠𝗲:
I’ve led products end-to-end, which means from system design and architecture to frontend engineering, performance optimization, and shipping under real-world constraints. My core expertise is in React, Next.js, React Native, TypeScript, and modern frontend stacks, with a strong focus on clean, intuitive, high-performance user experiences.
Beyond engineering, I worked closely on sales enablement, operations, product strategy, and go-to-market execution, which sharpened my ability to:
✔ Translate business and revenue problems into scalable technical solutions
✔ Build reliable systems aligned with sales and operational workflows
✔ Collaborate with founders, sales, and ops teams to ship what actually sells
✔ Move fast without compromising code quality, UX, or long-term maintainability
I thrive in high-ownership, remote-first environments where engineers are expected to own outcomes, not just tickets.
I build because I genuinely love it — not just as a job, but as a craft.
