    .NET PDF Document Creator Website
    6 ngày left
    Đã xác thực

    I need a small, secure website built on .NET where registered users can log in, choose from a set of predefined templates, and instantly generate a finished PDF. The workflow is straightforward: • Users authenticate through a standard login screen (ASP.NET Identity is fine). • After login they see a dashboard listing the available templates. Payment Gateway required. • When a template is selected, questionairre is uploaded, the user completes the questionaire, the system pulls the relevant data automatically— from a SQL-based data source and from a simple form the user completes—and merges it into the template. • The completed document is rendered as a PDF, reviewed to the admin team, once approved, then offered for download and optionally emailed to t...

    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...

    Two to three seasoned full-stack engineers are needed to push a complex, production-grade banking platform forward. The application’s backbone is .NET Core, the UI is written in Angular, and critical jobs run as Azure Functions, all talking to a SQL Server datastore. Your day-to-day work will revolve around: • Designing and coding new features end-to-end in .NET Core and Angular • Writing and refactoring serverless logic inside Azure Functions • Optimising queries and data models in SQL Server • Raising pull requests, performing code reviews, and managing branches in GitHub • Updating stories and tasks in Jira while collaborating in two-week sprints The environment is fast-moving and highly regulated, so I value developers who already have 6-8 year...

    I need hands-on assistance, at my Bengaluru office, to keep a live .NET 6 back end and Angular 12 front end running smoothly. The immediate focus is two-fold: • Systematic bug fixing—tracing issues in the Web API, Angular components, and integration layers, then committing clean, tested patches. • Regular code reviews—walking through pull requests with me, flagging design or performance concerns, and suggesting improvements that align with current best practices. Expect to work directly on the existing Git branch structure (Visual Studio / VS Code, Git, and typical dev-ops tools are already in place). Face-to-face collaboration during standard weekday hours is essential; remote work is not an option for this engagement. Deliverables will be accepted once each id...

    The core of my project is an API service already running on .NET 5 and paired with an Angular front-end. I need hands-on, task-based support to keep new features moving quickly while maintaining clean, testable code. Here’s the current stack and workflow so you know what you’ll be jumping into: • Backend: ASP.NET Core 5, Entity Framework Core, RESTful endpoints. • Front-end: Angular (latest stable), RxJS, Material. • DevOps: Git, pull-request reviews, CI builds on GitHub Actions. Typical tasks you could pick up include: • Expanding endpoints and DTOs. • Wiring new Angular components to the fresh endpoints. • Adding unit / integration tests where coverage is thin. • Fine-tuning performance or refactoring when technical debt appe...

    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...

    .NET MAUI App

    I need a lightweight .NET MAUI mobile application that targets Android and contains only three screens: • Login – users choose Face ID/biometrics, an NFC badge tap, or a numeric PIN to sign in. • WebView – after authentication the app simply embeds a URL that I will provide at build time. • Admin – a management screen (hidden behind its own sign-in) where I can add or edit users, assign permissions, and tweak basic app settings. All data, including user credentials, roles and configuration, must live in a MySQL database accessed through a secure REST API that you will craft and integrate. Please separate API, data-access and front-end layers cleanly and keep the code in MVVM pattern. C#, .NET 8, Entity Framework (or Dapper), Visual Studio and standard...

    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.

The work covers the entire cycle: architecture decisions, coding, UI polish, thorough testing, and packaging for deployment on current Windows versions. I’ll share the functional outline and existing mock-ups as soon as we connect; clean, well-commented code and brief setup notes will serve as the final deliverables, alongside the signed installer. If you’ve shipped at least one production-grade desktop app in .NET and can point me to it, we can get started right away.

    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.

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...
