About this gig

Need a bug fixed or a feature added to an Angular and ASP.NET Core web application?


I work professionally with Angular, TypeScript, C#, and ASP.NET Core. I can diagnose issues and implement focused improvements across the frontend, backend, APIs, and database layer.


I can help with:

  • Angular components, forms, routing, state, and responsive behavior
  • ASP.NET Core endpoints, services, validation, and business logic
  • API and database integrations
  • Authentication and authorization issues
  • Performance problems, refactoring, and automated tests
  • New features within an existing application


How it works:

  1. You provide the requirements, reproduction steps, and setup instructions.
  2. I review the scope and confirm the appropriate package.
  3. I implement and test the agreed changes.
  4. I deliver the updated source code with a summary of the work.


Packages are based on estimated development time. Revisions cover corrections required to meet the agreed scope. New features or changed requirements require an extra or custom offer.


Please message me before ordering when the issue is complex, difficult to reproduce, or spans multiple systems. I communicate in English and Spanish.
