Angular 12 to 18 Codebase Upgrade • $300 USD

⁠ Absolutely outstanding experience working with Roman! He successfully upgraded our Angular application from version 12 to 18 without introducing any regressions or breaking existing functionality. His attention to detail, deep understanding of Angular internals, and commitment to clean, maintainable code impressed me. Communication was smooth, and the project was delivered ahead of schedule. Highly recommended! ⁠
