I will debug, fix, and optimize your sencha extjs application

About this gig
Stop risking your enterprise application with generalist developers. Hire a true Sencha ExtJS Expert with 20+ years of IT experience.
Many modern developers only know React or Vue and get completely lost when opening an ExtJS codebase. I have been working with Sencha ExtJS for over a decade, mastering its evolution from ExtJS 2 to ExtJS 4, up to the modern ExtJS 7+.
Whether you have a legacy corporate system that needs urgent maintenance or a modern enterprise app with complex data requirements, I provide clean, scalable, and professional solutions.
What I can do for your ExtJS Project:
- Advanced Debugging: Fixing layout conflicts, component rendering issues, and console errors.
- Data Management: Troubleshooting Data Stores, Proxies, Models, and complex Buffering/Locking Grids.
- Architecture Review: Fixing issues in MVC (Controllers) and MVVM (ViewModels/ViewControllers) setups.
- Legacy Support & Migration: Helping you understand how to maintain or upgrade older codebases (ExtJS 2, 3, 4, 5, 6).
- API Integration: Seamlessly binding your frontend components to backend REST APIs.
Why choose me?
- Deep Framework Knowledge: I don't guess; I know exa
