Project details

I will upgrade your Angular application to a newer version and fix migration-related issues.

Angular upgrades often require more than updating package versions. Projects may have breaking changes in Angular CLI, TypeScript, RxJS, build tools, routing, forms, SSR/PWA setup, UI libraries, or third-party dependencies.

I will review your project structure, package.json, dependencies, and current build errors, then upgrade Angular and fix the issues required to make the project build and run correctly.

This service is suitable for Angular version upgrades, dependency updates, build error fixes, package compatibility issues, and basic functionality checks after migration. The final scope depends on your current Angular version, target version, project size, and third-party libraries used in the application.

I am a Full-Stack Developer specializing in Angular, .NET, SQL, and modern business web applications.

I have been working in web development since 2019, with strong experience in Angular, TypeScript, HTML, CSS, JavaScript, responsive UI development, single-page applications, dashboards, admin panels, SaaS interfaces, and modern web platforms.

On the front-end side, I work with Angular, Angular SSR, PWA, responsive layouts, UI implementation from Figma, API integration, performance optimization, and clean component-based architecture.

On the back-end side, I work with .NET, REST API development, authentication, authorization, business logic, SQL, PostgreSQL, and database integration. I can also use Node.js for lightweight back-end tasks, integrations, forms, small web projects, and simple APIs.

I can help you with:

* Full-stack web application development

* .NET REST API development
* SQL / PostgreSQL database integration
* Admin panels, dashboards, and SaaS applications
* Authentication and authorization
* Bug fixing and feature development
* Figma to responsive Angular layout

I focus on clean code, practical architecture, reliable communication, and solutions that are easy to maintain, extend, and use in real business.
