    I’m building a new web application and need an experienced ASP.NET MVC developer to turn my functional requirements into a polished, production-ready site. The stack is already set: C#, ASP.NET MVC, HTML5, CSS3, Bootstrap 4/5 for a responsive front end, and Microsoft SQL Server on the back end. Here’s what I need done: • Set up a clean Visual Studio solution with separate projects for UI, business logic, and data access. • Design and implement database schema in SQL Server, including tables, indexes, stored procedures, and necessary relationships. • Create models, controllers, and razor views that follow best practices for separation of concerns and clean coding standards. • Style every view using Bootstrap so the interface is fully responsive on des...

    I want to roll out a single API panel that lets my platform handle mobile recharges, utility bill payments, and DTH recharges in one place. The goal is a clean set of endpoints I can drop straight into my current codebase, together with a lightweight web interface where I can view traffic, transaction status, and basic error logs. Here is what I need delivered: • RESTful or JSON-RPC endpoints for the three services listed above. • A minimal dashboard (PHP, Node, or Python—your call) showing transaction history, amounts, and provider response codes. • Clear, commented documentation that lets another developer — or future me — wire new front-end screens without guessing. If you have suggestions on best-practice security or ...

    I built a C# .NET 8 desktop application that leverages the ChatGPT API to turn a prompt into a full presentation, then exports it to Word and PDF. The app also lets users switch between light and dark themes. Everything works—except the light theme only flips the text colour. The background, buttons, navigation menu, text fields and every other UI element stay in their dark-mode styling. That’s the first issue to solve. While you are inside the codebase, I also want to extend the editing workflow. When users highlight any generated text, a right-click context menu should appear where they can choose a tone (e.g. formal, casual, persuasive, etc.) and an action—Summarise or Expand. The selected text, tone and action are then sent to ChatGPT and the response should overwrit...

Your main mission is to design and implement the entire server side in .NET (Core 6 or later is fine), then expose clean, versioned endpoints that cover: • User authentication and role-based authorization • Fast, reliable data storage and retrieval (SQL Server or a lightweight alternative—whatever fits) • All business-logic processing, kept neatly behind service interfaces Along the way we’ll be integrating three categor...

    This is a little task to see who I select for further work on my project. Ongoing work on this project would be at a negotiated hourly rate, separate to the prize of this contest. Build a small .NET minimal API that exposes a single GET endpoint which, given a userId (Guid), returns whether that user is subscribed or not (true/false). You may mock any persistence functionality as needed, but assume the project could later use EF for ORM. The functional requirement is intentionally simple because the primary goal of this exercise is actually to evaluate how you structure and design the project. I’m interested in things like your project layout and design patterns rather than just the endpoint working. For example, there’s only one place where fat lambdas belong and that&rsqu...

Kullanılabilirlik ilk önceliğim; kullanıcı arayüzünün karmaşık ayarlarla boğuşmadan, sürükle-bırak mantığıyla ekran tasarlamaya izin vermesini istiyorum. Masaüstü, tablet ve mobil tarayıcılarda tutarlı görünmesi kritik, dolayısıyla responsive tasarım baştan düşünülmeli. Gerçek-zamanlı veri akışı ve komut geri bildirimi için SignalR altyapısının sorunsuz işlemesi, .Net Core MVC üzerinde katmanlı ve ölçeklenebilir bir mimari kurulması gerekiyor. PLC ekl...

    Project Title: Need .NET Developer to Fix False Antivirus/SmartScreen Detection (EXE Protection & Encryption) Project Description: I have a .NET software that I fully own and developed for legal purposes. The software builds a Windows EXE file, but after generating the EXE, I am facing false security detections: • If I put the EXE in any folder, Microsoft Defender automatically deletes it without even running the file. • When downloading the EXE using Google Chrome, the browser shows a red warning saying the file may be unsafe. • SmartScreen also blocks the EXE even though the program is completely legitimate. I need a professional .NET encryption/protection developer to build a security layer so that my EXE is not flagged incorrectly. Requirements: The developer...

    A brand-new web-based store is taking shape on the .NET stack, and the next milestone is a full feature buildout from database to responsive UI. The project already has its high-level architecture sketched in ASP.NET Core, but I need the full stack pulled together—front-end Razor Views (or Blazor if you prefer), C# business logic, Entity Framework data layer, and deployment to Azure or IIS. Core objective The site will function as a complete e-commerce platform. Beyond the usual catalog, cart, and checkout flow, the standout requirement is a robust Support module. Think customer ticketing with status tracking, optional live-chat handoff, and an admin dashboard that surfaces unresolved issues at a glance. Clean code, layered architecture, and solid security (OAuth 2 / Identity) are...

    I run a small-to-medium transportation business and need a Windows desktop application that keeps every moving part of my fleet in one place. The core idea is simple: each driver, vehicle, trip and rupee spent or earned must be captured once and reported back to me whenever I ask. Key workflows I need covered • Driver advances and deductions – when I hand cash to a driver, I want to enter it immediately so the amount is automatically deducted from that month’s salary calculation. • Trip logging – date, route, freight earned and the vehicle used. This should let me see per-vehicle earnings at a glance. • Vehicle expenses – fuel, repairs, FC, insurance and any other mechanical cost recorded against the correct truck or van. • Reminders &nd...

    • Description Your objective is to create a WinForm demo which consumes all the Restful and subscription API in the documentation. Below is the specification. There is also a sample Java code available if you need it. The result is that we click on the button, and the action is launched successfully. Please implement all functions. Please start by logging into the platform successfully first, then code your logic in each button in WinForm. Please make sure you can log in via the API, as all subsequent actions rely on being able to log in. You can also verify your API post/input via the MATS platform. For the WinForm, please use Visual Studio, drag and drop the button from the toolbox and double click. This will make the code cleaner. Your work will be tested, and all b...

    Trabalho com C# e Windows Forms e preciso que, ao acionar um botão na tela principal, um novo formulário apareça exatamente sobre ela, ocupando o foco e impedindo qualquer clique ou rolagem no formulário que fica por baixo. Em outras palavras, a nova janela deve ser modal, bloqueando completamente a interação com a tela existente até que o usuário a feche. Não me preocupo em seguir o mesmo design da tela atual; se o novo formulário tiver um visual independente já atende ao que preciso. Fico à vontade para usar recursos padrão de WinForms (ShowDialog, Owner, TopMost, etc.) ou alguma outra abordagem enxuta que garanta o comportamento modal sem efeitos colaterais. Aceito tanto um pequeno projeto exemp...
