Over deze dienst

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.

    Engels
Senior web engineer and web architect with 15 years of experience in front-end architecture and legacy application modernisation. I help teams migrate large legacy applications to modern web stacks with a clear, documented plan. I built an ANTLR4 and Node.js tool that converted 600+ business modules from a C#/WPF desktop application to Vue 3, plus dependency-mapping and complexity-analysis tools. I also work with Vue 2/3, TypeScript, JavaScript, jQuery, micro-frontends, Electron, Java/Spring Boot, GIS and API integration. I communicate asynchronously across time zones and document decisions.
