I will review a legacy frontend codebase and create a migration plan


About this gig
Need to fix, modernize, or migrate an existing web application?
I specialize in legacy web application migration, Vue development, and complex front-end refactoring.
I can help with:
Vue 2 to Vue 3 migration
JavaScript / TypeScript bug fixing
Legacy code refactoring and modernization
C#/WPF application migration to Vue 3
Knockout / jQuery modernization
Front-end architecture and component refactoring
Existing page or module migration
API integration and integration issues
I have 15 years of software engineering experience and have worked on large enterprise applications, including building an ANTLR4-based migration tool that converted 600+ business modules from C#/WPF to Vue 3.
My focus is existing systems that need careful analysis, migration, or repair not generic template websites.
Before starting, I will review the existing code and scope and provide a clear written plan.
Please message me before ordering for legacy migration or complex issues, as every codebase is different.
I work primarily through clear written communication and provide progress updates and verification instructions with delivery.
