Professional Frontend Bug Fixing & Debugging
Is a critical UI element broken? Is your React state behaving unpredictably, or is a "simple" CSS issue ruining your mobile experience?
Don't let bugs stall your launch or drive away users. I specialize in surgical frontend debugging, identifying root causes, and implementing clean, permanent fixes that won't break your codebase elsewhere.
My Debugging & Repair Services:
Logical & State Errors: Fixing broken Redux/Zustand flows, useEffect infinite loops, and "stale" data issues.
UI/UX & CSS Rescue: Resolving layout shifts, z-index headaches, and "not responsive" bugs across all browsers.
API & Integration Fixes: Debugging failed fetch/axios requests, authentication loops, and malformed data handling.
Performance Bottlenecks: Identifying memory leaks and heavy re-renders that slow down your user experience.
Console & Build Errors: Clearing those stubborn red errors in the browser console or fixing Webpack/Vite build failures.
Why Hire Me to Fix Your Code?
Deep Investigation: I don’t just "patch" the symptom; I find the root cause so the bug doesn't come back

What can I Bring to the Table?
-Expertise in React: I specialise in creating seamless, dynamic user experiences with React.
-Advanced React and Redux Toolkit Proficiency: I bring in-depth knowledge of React's ecosystem, leveraging Redux Toolkit for efficient state management, resulting in faster development times and more robust applications.
-Expertise in Error Monitoring with Sentry: My experience with Sentry has enabled me to swiftly diagnose and rectify errors, ensuring high reliability and enhancing user satisfaction.
-Experience with NX Monorepos: Working with NX has sharpened my skills in managing large-scale projects with multiple interdependent applications and libraries, promoting code reusability and consistency across the board.
-Strong Foundation in TypeScript: My commitment to TypeScript enhances code quality and maintainability, providing a solid type system and enabling early detection of potential bugs.
User-Centric Development: I believe that at the heart of every successful application is a great user experience. I design and develop with the end-user in mind, ensuring that interfaces are intuitive, responsive, and accessible.
Collaboration and Communication: I understand the importance of clear communication and collaboration, especially in remote and distributed teams. I'm known for my ability to break down complex technical challenges into understandable language and work closely with team members across different domains.
My Experience:
Over the last four years, I've had the privilege of working on a wide range of projects, from startup MVPs to complex enterprise applications.
Some highlights include:
- Developed and maintained a feature-rich application using React and Redux Toolkit.
-Integrated Sentry into existing projects, reducing error resolution times by aprox 50% and significantly improving application stability.
-Transitioned a complex project to an NX monorepo setup, enhancing team collaboration and streamlining the development process.
-Refactored a large-scale application to TypeScript, improving development efficiency and reducing runtime errors by a big percentage.
- Optimising the performance of a large-scale e-commerce site, achieving a 90+ score on Google PageSpeed Insights through code splitting, lazy loading, and server-side rendering.
