fix bugs and refactor your react and javascript code

Acerca de este Servicio

This gig is dedicated to resolving complex logic issues and executing deep structural refactoring for React and JavaScript applications. I go beyond basic patching to permanently eliminate technical debt and optimize your app's performance.


What to expect from this service:

  • AI Codebase Refactoring: For AI-generated apps that have become an unscalable, buggy mess, I rebuild AI-hallucinated code into a clean and easy-to-read codebase.
  • Targeted Logic Resolution: Fixing broken states, UI rendering bugs, and API integration failures.
  • Legacy Modernization: Upgrading outdated JS or messy React components into clean, modular architecture.
  • Performance Optimization: Slashing load times by removing dead code and restructuring data flow.
  • Verified Quality: Every deployment is rigorously tested on real desktop and iOS environments to ensure absolute stability.

️

PLEASE NOTE: Every codebase is unique. Please contact me before placing an order to discuss your project's complexity and establish an exact timeline.

    I needed a solution to create 'with a single click' a PDF file containing both text and automatically generated financial charts based on a combination of HTML and JavaScript. Excellent delivery, on time, great communication along the way and very well documented. Highly recommend!

    Was great working with Alexandra. Needed help to rewrite / optimize a code for charts generation in Javascript. Not a simple project, still good final result and great communication along the way. Will surely come back with additional projects.
