You will get a custom Chrome Extension with Manifest V3
Project details
Need a custom Chrome Extension to automate tasks, interact with websites, connect to APIs, or add functionality to your existing web application? I will develop a professional Chrome Extension using Manifest V3 tailored to your requirements.
With experience building Chrome Extensions and integrating them with web applications, REST APIs, authentication systems, payment platforms, and backend services, I can develop everything from simple browser utilities to more advanced SaaS-connected extensions.
Depending on your selected package, I can work with content scripts, service workers, Chrome Storage, messaging, API integrations, authentication, web-page interaction, automation workflows, and third-party services.
I can also connect your extension to a .NET/ASP.NET Core backend, enabling features such as user accounts, subscriptions, usage limits, centralized data, and SaaS functionality.
This project is suitable for business automation, productivity tools, SaaS products, data extraction, web workflows, internal tools, and browser-based applications.

My technical expertise
Backend: C#, .NET, ASP.NET Core, Web API, Entity Framework Core, Dapper, LINQ
Frontend: Blazor, JavaScript, jQuery, HTML, CSS
Databases: SQL Server, PostgreSQL, MySQL
Desktop: WPF, WinForms

I approach projects from both an engineering and product perspective. I care about clean architecture and maintainability, but also about usability, performance, security, scalability, and how the software will work in a real business environment.
Whether you need to build a new SaaS product, develop an MVP, extend an existing .NET application, create a Chrome Extension, integrate AI or payments, or troubleshoot a difficult backend problem, I can take ownership from development through delivery.
If you have a product idea or an existing application that needs a senior .NET engineer, let's discuss it.
Steps for completing your project
After purchasing the project, send requirements so Rahul can start the project.
Delivery time starts when Rahul receives requirements from you.
Rahul works on your project following the steps below.
Revisions may occur after the delivery date.
Review extension requirements
I'll review the required features, target websites, user workflow, permissions, and technical requirements.
Design the extension architecture
I'll define the Manifest V3 structure, popup, content scripts, service worker, storage, permissions, and API communication.
