    SOLID .NET Sorting App
    6 days left
    Verified

    I need a clean, well-structured console application in C# (.NET 6 or later) that solves the sorting problem detailed in the attachment. The core requirements are: • Apply every SOLID principle from the ground up—single-responsibility classes, clear abstractions, and no hard-wired dependencies. • Use (or a comparable container) so I can swap sorting strategies without touching Program.cs. • Implement the specific sorting routine exactly as described in the attachment. If the brief allows freedom of choice, a working Quick, Merge, or Bubble version is acceptable as long as the output matches the specification; additional implementations are welcome. • Accept unsorted data via stdin or a simple file path argument, perform the sort, then echo the ordered resul...

    I have a C# / .NET application whose source code must stay confidential. Commercial tools like DNGuard still leave traces I consider readable, so I’m looking for a stronger, tailor-made obfuscation system. Here’s what I need you to deliver: • An advanced obfuscation strategy focused on protecting source code only—data, resources, licensing, and activation aren’t in scope. • Robust techniques such as symbol renaming, control-flow mutation, string and metadata encryption, anti-decompilation stubs, and tamper detection, combined in a way that clearly outperforms DNGuard’s default profile. • A repeatable build process (MSBuild task, CLI, or Visual Studio plug-in) so I can apply the protection to future releases without manual steps. &bull...

    I use a Sartorius PMA-HD weighing scale and want to read its live weight values inside my own software instead of the bundled utility. Your task is to create a lightweight Windows desktop application that: • Connects to the PMA-HD through its standard PC interface (serial/USB). • Continuously retrieves the current weight reading. • Displays the value on-screen in real time and exposes it in a simple form I can reuse later (e.g., a local text file, clipboard copy, or tiny REST/IPC endpoint—whichever is quickest for this first version). Keep the build uncomplicated—think of it as a basic proof-of-concept I can expand on later.

It displays the data provided by the model and sends user commands to the controller. 3. **Cont...

    I’m looking for a skilled software developer who can take my functional requirements and turn them into a reliable desktop application. The main goals are clarity, speed, and maintainability. Key points • Platform flexibility – I’m open to Windows, macOS, Linux, or a truly cross-platform stack such as Electron, Qt, .NET MAUI, or JavaFX. Recommend what best fits long-term stability and cost. • Core build – create a working desktop app with a clean, intuitive UI, secure user authentication, and a lightweight local database (SQLite, LiteDB, or similar). • Code quality – well-structured, modular code, inline comments, and a concise README so future developers can jump in quickly. • Deliverables – compiled installer, full source c...

    I need a compact banking software tool that focuses on transaction processing. The first milestone is a working module that can execute and log fund transfers between accounts in real time, with the flexibility to accommodate other transaction types later. Core requirements • Fund-transfer engine: debit/credit logic, double-entry records, reversal handling, and daily reconciliation report. • Security: token-based authentication, role-based access, encrypted data at rest and in transit. • Integration: REST/JSON API that plugs directly into existing online banking portals; clear sample calls and webhook support for status updates. • Audit & compliance: immutable transaction log, timestamped events, and basic fraud-alert hooks. Deliverables 1. Functional protot...

    I’m looking for a compact desktop application that lets our employees easily share three kinds of input—Performance reviews, Work environment feedback, and Suggestions for improvement—then stores that data for quick reporting. Core objectives • Simple, installer-based desktop build (Windows preferred, but I’m open to cross-platform frameworks such as Electron, .NET, or Python + Tkinter). • Clean form where an employee selects the feedback type, rates on a 1-5 scale, adds optional comments, and submits. • Local database or lightweight file storage to hold the entries. • Basic admin screen to view, filter, and export feedback to CSV. What I’ll provide • Rating categories and wording for each field. • Brand colours and logo...

    Hey, I need some help with my **fully external C++ ImGui project** that interacts with cod.exe. The main task is to **fix controller support**. Right now, all the logic and hotkeys are already in the code, and **mouse input is working perfectly in-game** — including aim and lock-on behavior. However, the **controller support isn’t working** because for controllers, you need to handle 3D angles, while mouse events only use 2D input. **In short:** * Mouse events use 2D input logic (which is already working). * Controller support needs 3D angle logic to properly aim and lock on to players. **What you’ll need to do:** * Implement the correct 3D angle calculations for controller input. * Make controller aiming behave the same as mouse aiming in-game. * Check and fix any co...

    We have an established C#, ASP.NET MVC web application that needs a round of change management focused on adding new functionality rather than simply fixing bugs. I’m looking for a developer who is equally comfortable with design decisions and hands-on coding and who can move efficiently between the front end and the data layer. The task : • Analyse the current solution, identify extension points and map out a clean approach for change & new module development. • Build new data-processing functions end to end: controller actions, business-logic services, and the underlying SQL Server and Oracle objects (tables, views, procedures). Including Front & backend coding . • Refactor or extend existing screens so the new modules fit seamlessly into the user exp...

    I already have C# code in Visual Studio that reads varbinary(max) BLOBs from several SQL Server tables, converts each file to JPEG, and stores the result in MongoDB. What I need now is a hands-free, reliable way to run this pipeline on a set schedule—every night—while expanding it to cover additional tables and capturing solid run-time logging. The only image processing involved is format conversion; no resizing or compression is required at this stage, though the design should leave room for those features later. I am flexible on the exact scheduling mechanism as long as it runs automatically (SQL Server Agent, Windows Task Scheduler, or a lightweight service are all fine) and can retry or alert on failure. Deliverables • Refactored C# solution with clear project struct...
