ASP.NET Jobs

I need an experienced .NET full-stack developer to move several in-house web projects forward. Most of the work circles around ASP.NET Core (MVC and Web API) backed by SQL Server, with the user interface rendered in Bootstrap. Scope of work • Build new modules and, where necessary, refactor legacy .NET code into a clean, layered architecture. • Design and optimise SQL Server tables, views, stored procedures and indexes to keep the app fast under load. • Implement an admin area focused on Analytics graphs; charting libraries that work smoothly inside Bootstrap are welcome. • Secure the application with claims- and cookie-based authentication, plus role-based authorisation throughout. • Integrate third-party REST APIs, handle error cases gracefully, and ...

I maintain a live Angular + Dotnet Core application and need someone who can sit with me in Bangalore—preferably on-site, at least for the first few sessions—to quickly enhance the backend. The core goal is to improve an existing system, not start from scratch. Right now the Dotnet Core layer is showing its cracks: data isn’t syncing cleanly between services and several API calls are failing on production, causing intermittent errors in the Angular front-end. I’d like you to dive straight into the repository, isolate the synchronization logic, patch the API communication issues, and leave the codebase cleaner and easier to extend. Key deliverables • Stable, fully functioning Dotnet Core backend with no data synchronization lapses • API endpoints retu...

My existing ASP.NET-based site (C#, SQL Server) is ready for live payments; the missing piece is a clean, fully-tested connection to the ICICI Bank payment gateway. The integration has to handle three flows—one-time charges, recurring billing cycles, and full or partial refunds—without persisting any card data on our servers. Key deliverables • Seamless server-side code that calls ICICI’s API for payments, subscription creation, and refunds, then returns clear success/error responses to the UI. • Web-configurable credentials and callback URLs so I can switch between sandbox and production by editing settings, not code. • Token-based implementation that keeps us out of PCI scope (no storage of card details). • Brief deployment guide and inlin...

I have an existing backend written in .NET Core that exposes a RESTful API. I now need a hand with two things: expanding the API with a few new endpoints and squashing some stubborn bugs that are affecting current routes. The codebase sits in a private Git repository and builds cleanly with the dotnet CLI. You’ll get a detailed list of the endpoints to add or refactor, the steps that reproduce each bug, and a Postman collection for quick regression checks. Once we agree on the work, simply branch, code, test, and open a pull request. Deliverables I expect: • Updated or brand-new C# controllers, services, and any supporting classes that compile against .NET Core. • Targeted bug fixes with unit tests that prove the issue is resolved. • A brief changelog so I can re...

My ASP .NET website loads fine until the moment a user logs in—right after pressing the Login button an error message pops up and the page stops there. I can capture and share a screenshot of the exact message, but I don’t have the text copied out. Nothing else needs to be clicked for the issue to appear; it happens instantly after authentication. I’m looking for someone willing to troubleshoot this one-off problem pro bono. You’ll have temporary access to the project files or a zipped copy (C#, .NET Framework, SQL Server back-end) so you can replicate and patch the fault. Once you identify the cause and supply the fix—whether it’s a tweak, an authentication middleware adjustment, or a code-behind patch—I’ll implement it on the live serve...

I already have a web-based EHR written in .NET that stalled before launch. The core workflows are in place, yet three areas still block us from going live: • Bug fixing (top priority): the current build shows several UI/UX inconsistencies, a handful of security gaps around authentication/authorization, and broken FHIR calls that return empty payloads or 500 errors. • FHIR integration: the R4 endpoints exist but half of the resources are unmapped and the conformance statement fails validation. . I need someone who has shipped an EHR or similar health-tech product, is comfortable working in C#, ASP.NET Core, Entity Framework, and knows the HL7 FHIR spec inside out. Familiarity with ONC certification criteria—USCDI data classes, SMART on FHIR launch, etc.—will make...

The application should include: Roles: - Admin: Manage system and users - Registered User: Book flights and cancel bookings Key Features: - Login/Registration: ask new users to register and then login to secure access for users - User/Admin Interface: users book, cancel, select payment option, and also can get smart destination recommendations Admins manage users, flights(add/edit), bookings, cancellations. - Booking/Cancellation flight reservations - Basic Payment Options: Credit/Debit Card, Bank Transfer - Smart Destination Recommendation: Suggest budget-friendly destinations based on user’s budget, travel type, source, departure date Idea...

I am building a fully-featured social networking platform from the ground up and need a developer who can own both the server-side and front-end work. The stack is set: C# ASP.NET (Core preferred) powered by an MS-SQL database. Scope of work You’ll start by architecting the database, spinning up the ASP.NET project, and exposing a clean, well-documented REST (or GraphQL, if you prefer) API. Identity-based authentication, role management, and token-based security need to be wired in from day one. Key features I must see at launch: • Messaging system (asynchronous and real-time) • News feed with post, comment, like, and share capabilities • Private chat using SignalR or an equivalent WebSocket solution • Meeting scheduling module that lets users create, ...

I need an experienced .NET and React developer who can give my product a full-time focus—eight hours a day for the next month—while working side-by-side with my lead engineer during Indian Standard Time. The codebase is already in production; our goal over the coming weeks is to tidy up rough edges, harden performance, and keep new issues from sneaking in as we roll out incremental updates. Tech stack you’ll touch daily: ASP.NET Core APIs, a React front end that leans on hooks and functional components, JSON-heavy data exchange, and Azure resources provisioned with Bicep. You’ll be handling pull requests, writing clean commits, and jumping on quick Teams or Slack calls whenever a change needs clarification. Expect a straightforward workflow—branch, code, PR, ...

I want a Blazor WebAssembly application that my team can run entirely in the browser while still taking advantage of .NET on the back end. The project’s focus is an internal business app, so security, speed, and a clean code-base are more important to me than public-facing design polish. Core features I need working from day one: • User authentication – sign-in, sign-out, role-based access, and token refresh handled with ASP.NET Core Identity or another proven library. • Data visualization – interactive charts and tables (think , Plotly, or the built-in Telerik/Syncfusion components if you prefer) driven by live data pulled from our existing APIs. • File uploads – drag-and-drop or standard picker that writes to a secure storage endpoint, then d...

I am spinning up a fresh Windows Server 2022 instance on AWS EC2 and need it to behave exactly like our current Windows Server 2016 EC2 box. The goal is zero-difference for end-users once we switch over. Here is what must work out of the gate: • Classic ASP and IIS hosting for all of our existing sites, with bindings, SSL certificates, and application pools duplicated as they stand now. • Database services mirrored so every connection string continues to resolve without edits. • Third-party components already in use—including but not limited to: Auth0 for user authentication, the WodCrypt encryption library ( ), and ABCpdf from —installed, registered, and tested so the sites compile and run just as they do today. You will receive remote access to both the...

The immediate milestone is to stand up a fully-functional DocuSign environment inside our C# / ASP.NET Core platform. Within that integration I need three things working seamlessly: • each template must pull the correct rates and monetary values into every field, • document workflows have to fire automatically from creation through signature, and • the whole flow must hook into our existing system endpoints without manual intervention. Because no formal documentation for those rates and values exists, you and I will map the data together, define the XML schema that will carry the information, and wire that schema to the DocuSign API. Once the DocuSign piece is solid we can move on to the wider XML-driven automation logic and, finally, a performance-oriented redesig...
