I need a very small Universal Windows Platform (UWP) application whose sole purpose is to launch a local batch file, which in turn starts my existing Java-based desktop application. Once the finished UWP package has been provided, I will configure it as the single locked-down app in Windows 11 Assigned Access, so please also supply the Application User Model ID (AUMID). The launcher should display no user interface at all — no buttons, splash screen, status messages or other visible elements. Its only function is to execute a batch file stored locally on the device, using a path I will provide, and then hand off control to the Java application. No additional security controls, keyboard restrictions or logging are required; reliability, simplicity and a clean hand-off are the priorit...

I already have a fully documented API and need a Windows desktop application that consumes it smoothly. Your task is to create a reliable, user-friendly executable that interacts with the endpoints I supply, handles all requests and responses gracefully, and displays the data in a clean interface. You are free to choose the stack you are most comfortable with—C#/.NET (WPF or WinForms), Electron, or another Windows-friendly framework—so long as the final program runs natively on current Windows versions, installs easily, and requires no extra licensing costs. Deliverables • Compiled Windows installer (.exe or .msi) • Complete, well-commented source code • Brief README covering build steps, environment, and any third-party libraries • Basic user guid...

My automated trading bot runs on NinjaTrader 8 and already executes live orders, yet its current build eats up more resources than necessary and still misses the occasional signal. I want the codebase cleaned up and strengthened—no AI shortcuts, just solid C# engineering. Performance goals • Reduce CPU / memory load so the bot can stay active on multiple instruments without slowing the platform. • Tighten calculation logic and order-routing routines to boost signal accuracy and limit slippage. Functional goals • Add agreed-upon new features—think smarter risk controls or additional indicator inputs—built directly into the existing strategy class. • Rework current functions to be clearer, faster, and easier to maintain; comments and naming...

Hi there, I need a full-stack developer, or team, to build a multi-tenant logistics management system built on Angular 14 for the front-end, .NET Core for the API layer, and SQL Server as the data store. The one capability that must be solid from day one is Fleet management—vehicles, routes, and operational data must stay completely segregated per tenant while sharing the same codebase and database. Everything has to scale cleanly as new companies sign up, so tenant isolation, role-based access, and configurable settings are essential parts of the architecture. Core scope • Set up the tenant-aware user authentication/authorization flow (JWT or similar) • Design the SQL Server schema with row-level or schema-level isolation to keep each tenant’s fleet data separate ...

I have several Windows executables and accompanying .dll files that were originally written in C, but the source code has been lost. I will supply only those compiled binaries; no partial code or documentation is available. Your task is to work through the binaries, reconstruct human-readable, buildable C source, and document any non-obvious logic you uncover along the way. I expect the recovered code to compile on a current GCC/Clang toolchain, reproduce the original behaviour, and be organised into clear modules with meaningful comments. Feel free to use IDA Pro, Ghidra, Hopper, Radare2, or any other reversing tools you are comfortable with—just note your workflow so I can maintain the codebase afterward. Deliverables • Complete C source tree that builds cleanly (no warn...

I run a growing chain of bakeries and now need a single, cohesive system that lets every outlet bill customers, track stock and feed all figures back to a central server. Compatibility • The point-of-sale itself must be a Windows desktop application that works offline when needed, then syncs continuously with a web-based server for consolidated data and remote management. Core scope • Billing & Sales tracking – quick item lookup, discount handling and GST-ready printable / digital receipts. • Inventory – real-time stock level tracking at each outlet, automatic deduction when a sale is made, and a central view so I can reorder in time. • Reporting – daily, weekly and monthly sales reports broken down by outlet, item and GST slab.

I am building a green-field fraud-detection platform and need an experienced back-end engineer to own the server-side work for the next three months. The stack is .NET (C#), PostgreSQL, and Redis; a separate team will handle the React front end, so your focus stays firmly on the APIs, data layer, and real-time processing pipeline. What the engagement looks like You will translate our detection logic into clean, well-tested C# services, design the relational schema in PostgreSQL, and use Redis for low-latency caching and message queues. Because the app is completely standalone, there are no third-party or legacy integrations to worry about—every decision you make will directly shape the core product. Key expectations • Produce readable, documented code that passes automated...

I’m building a C# web application in ASP.NET Core and I’m looking for an experienced developer who can jump in and accelerate the remaining work. The project centres on three pillars: solid user authentication, clear and responsive data visualisation, and reliable third-party API integration. Where I am now: the solution skeleton and basic routing are in place, but the heavy lifting on identity management, charting dashboards, and the external API logic still has to be completed and wired together cleanly. What I need from you: • Implement secure registration, login, and role-based access using ASP.NET Core Identity (or another approach you recommend, as long as it stays within the framework). • Build interactive charts/graphs that pull data from my existing E...

I’m spending far too much time re-typing purchase vouchers into Tally when everything is already organised in Excel. I need a small utility that reads those spreadsheets and posts each row as a purchase entry in my Tally company, with all taxes, supplier details and inventory lines carried over exactly as they appear in the sheet. You are free to choose the most efficient route—Tally XML import, ODBC, TDL, or a Python/.NET bridge—so long as the final result is a one-click (or near one-click) process that any non-technical staff member can run on a Windows machine. Deliverables • Executable tool or script with a simple UI or clear command-line instructions • Mapping configuration so I can point new spreadsheet layouts to the correct Tally fields without cod...

• Description The objective is to create a prototype that sends our XML string via AS4 to a destination URL. You can start with <test>dummy</test> for now, but we will test with real xml. You will need to sign with the internal private key certificate and encrypt with the external public key certificate. The other side will decrypt with their private key certificate and verify our signature with our public key certificate. We will give you the certificates. You will then listen to our URL. They will send an async message 10-15 minutes later. We will give you access to our VPS, so the DNS will be routed to the VPS. You will need to verify their signature with their public key and decrypt the message with our private key. Success metrics are that the message is successfull...

I have four Excel workbooks that I now need housed in an existing MS Access database. None of the sheets are relational at the moment, so the job is a straight import and structure clean-up rather than designing complex links. Here’s what I need from you: • Import 4 existing Excel Files into 4 tables in an existing MS Access DB (.ACCB) • Add a few basic queries so I can filter, sort and export the data quickly. • Delete bad data and duplicates The project is to be done in .net with WPF user interface. Once complete, send me the .accdb file and the brief how-to notes—that’s it. If something in the data suggests a better structure, feel free to flag it before you proceed; otherwise, a clean one-to-one migration is all I’m after.

We have a legacy Windows desktop application built on .NET Framework 4 that captures video from a USB webcam using and a custom wrapper WebCam_Capture.dll.

We need a freelancer to analyze, patch, and improve the camera handling logic so that the software consistently recognizes the camera across all machines. ⸻ Key Requirements / Skills: • Strong experience with .NET Framework 2.0–4.x and C# • Experience with DirectShow / video capture pipelines • Comfortable with Windows desktop apps (WinForms/WPF) • Experience with reverse engineering / decompiling .NET assem...

My WPF desktop app is halfway there; the core logic is working, but the presentation layer and final polish still need attention. I already have a detailed UI specification, so you can focus on bringing the remaining screens to life in XAML, wiring them cleanly into the MVVM structure, and making the whole thing run smoothly against a SQL Server back end. Here is what still needs doing: • Implement every control, style, animation, and layout exactly as shown in the spec. • Connect views to the existing SQL-driven data layer through well-structured ViewModels, keeping bindings clean and testable. • Profile memory, rendering, and startup behaviour, then eliminate the bottlenecks so large result sets scroll without stutter. I’ll hand over the current Visual Studio ...
