I will fix react performance, bugs, and optimize lighthouse scores


Over deze dienst
Since we are now focusing on Gig 2 (Performance & Speed), the description needs to be technical, results-oriented, and highlight your 25% speed boost claim.
Here is a 1,200-character description for your Performance & Bug Fix Gig:
High-Performance React Optimization & Bug Fixing
Is your React application lagging, buggy, or failing Core Web Vitals? A 1-second delay can cost thousands in lost revenue. As a Full-Stack Engineer (B.E. Computer Science) with 3+ years of experience, I specialize in transforming slow, unoptimized sites into lightning-fast, production-ready applications.
What I Deliver:
- Performance Optimization: I achieve 100/100 Lighthouse scores by implementing advanced code-splitting, lazy loading, and asset compression.
- Expert Bug Fixing: Rapid resolution of complex TypeScript errors, state management glitches (Redux/Zustand), and API integration issues.
- Speed Boost: I typically deliver a 25% increase in page load speeds, ensuring a smooth user experience.
- Clean Architecture: I don't just "patch" code; I refactor for long-term scalability and maintainability.
Stop losing users to slow load times. Lets get your application running at peak performance.

Veelgestelde vragen
Which tools do you use to measure my website’s performance?
I primarily use Google Lighthouse, PageSpeed Insights, and GTmetrix. I provide a "Before vs. After" report so you can see the exact improvements in Core Web Vitals, such as Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS).
Can you guarantee a 100/100 Lighthouse score?
While 100/100 is always the goal, the final score can depend on third-party scripts (like heavy tracking pixels or ads). However, I guarantee a significant boost in performance, typically aiming for 90+ on mobile and 100 on desktop by optimizing everything within the codebase.
Will the optimization break any of my website’s features?
No. As a Computer Science Engineer, I prioritize code integrity. I perform all optimizations in a staged environment or with local testing to ensure that functionality, styling, and user experience remain perfect while the speed increases.
What common issues do you fix to improve speed?
I focus on unused code removal, asset compression, lazy loading implementation, API call optimization, and reducing re-renders in React. I also implement code-splitting to ensure users only download the JavaScript they need for the page they are on.
Do you offer bug fixing for TypeScript and Redux?
Yes. I specialize in debugging complex Type-safety issues in TypeScript and resolving "state-drift" or performance bottlenecks in global state managers like Redux Toolkit, Zustand, or the Context API.
Does speed optimization help with my Google ranking (SEO)?
Absolutely. Google uses Core Web Vitals as a ranking factor. A faster, more responsive site reduces bounce rates and improves your search engine visibility, which is why my Premium package includes a Technical SEO audit.
