Existing Project (Expanzing Portal) ā Angular 14 ā 20 Upgrade, PrimeNG Upgrade & API Integration
Vaibhav exceeded our expectations on a challenging Angular modernization project. He successfully upgraded our application from Angular 14 to Angular 20, upgraded PrimeNG, resolved numerous compatibility issues, refactored deprecated code, and integrated multiple backend APIs without introducing regression issues.
His technical knowledge of Angular, RxJS, TypeScript, and enterprise application architecture was evident from day one. Rather than simply implementing requested changes, he proactively identified potential risks, suggested improvements, and helped us avoid future maintenance issues.
The quality of his code, attention to detail, and commitment to delivering a production-ready solution were outstanding. Communication was always clear, progress updates were consistent, and deadlines were met without compromise.
Vaibhav is a highly dependable full-stack developer who combines strong engineering skills with professionalism and accountability. We would confidently hire him again for future Angular, .NET, and enterprise application projects.
