.NET Jobs

I need access to battle-tested enterprise repositories that exceed 50,000 lines of code. The primary goal is to run AI benchmarking, perform deep architecture reviews, and carry out engineering evaluations for technical due-diligence work. Real-world complexity is essential—simple CRUD samples will be declined. Preferred technology foundations include Java, .NET, Python, Node.js, or React, ideally containerised with Docker or orchestrated through Kubernetes and deployed on AWS, Azure, or GCP. Repos hosted on GitHub, GitLab, Bitbucket, or a private Git server are all welcome. Any supplementary assets—such as PRD/BRD documents, Jira tickets, detailed API docs, architecture diagrams, deployment playbooks, or test artefacts—will significantly strengthen your submission and ...

I need a developer who has already completed a Malaysian MyInvois / e-Invoice integration to plug that same expertise into our web-based EMR (ASP.NET C#, Microsoft SQL Server). The immediate goal is automated invoice generation: every time a consultation, treatment or ancillary service is saved in the EMR, a compliant e-Invoice must be created in the background and transmitted to the LHDN MyInvois gateway without any manual touch points. You will work directly in our existing codebase, expose or consume the necessary REST endpoints, handle authentication and digital signing, and persist the MyInvois response so finance staff can retrieve the PDF or XML from inside the EMR UI. Please bring along any helper libraries, middleware components or stored-procedure strategies you have already pro...

I have the full concept for a PC-only 2D MMO sandbox inspired by Pixel Worlds and I’m ready to see it running. What I need right now is the playable foundation: account creation that stores credentials securely, a clean main menu that leads into the world, and enough networked infrastructure so I can begin plugging in the building, chat, trading, and character-customization systems I’ve already designed. As Of Right Now I just need the basics (Main Menu, Account creation and world making/saving if possible) Engine choice is open—Unity, Godot, or anything you’re comfortable with—as long as the end result is stable, well-commented, and easy for me to expand. A lightweight server back end (Node, .NET, or similar) plus a simple database for user data will be expe...

I need a lightweight Windows desktop application that lets me handle the everyday paperwork of freight management without fuss. The core flow is simple: I open the program, create or select a client, and immediately start filling out ledger entries that capture shipment details—origin, destination, weight, carrier, cost, and any reference numbers. As those records grow, I want to be able to pull clean summaries and printable reports at the click of a button. Must-haves • A ledger module where I can add, edit, and archive entries. • A shipment tracker that links each ledger line to its current status. • A reporting screen that filters by date range, client, or carrier and exports to PDF or Excel. • Smooth installation on modern Windows machines (Windows 10...

I need a single-file Windows executable that wraps the open-source LiveKit stack so I can spin up, host, and join video meetings on demand. I do not need a full graphical interface—basic, CLI-driven operation is fine—but the build must still expose three core features: screen sharing, session recording, and an in-meeting chat. Please use whichever language or tooling you prefer (Go, Node, Electron, .NET, etc.) provided the final deliverable is a stand-alone .exe that launches on Windows 10/11 without external installs. Source code, a concise README with build steps, and any minimal configuration files should accompany the binary. Acceptance criteria • The .exe starts a LiveKit room and allows another instance to join. • Screen sharing works between participants....

I need help now is a focused, advanced walkthrough on cracking ’s deobfuscation layer. What I want from you is a set of clear, well-structured video tutorials ( in person or offline)that show—step by step—how to unpack an assembly protected by , peel away its control-flow, string and metadata tricks, and rebuild readable, workable source. I’m not looking for surface-level theory; I need you to demonstrate real-world tooling in action, explain why each choice matters, and discuss subtle counter-measures deploys. Please base the recordings on tools you trust in your own workflow—whether that’s a customised de4dot fork, dnSpy, ILSpy plugins, or any purpose-built scripts you’ve crafted. Provide the protected sample binaries you work on so I can re...

I need a full-stack inventory management application that lets me create, read, update and delete every core entity—products, suppliers, categories and locations—through a clean web interface and a documented Web API. Real-time stock updates are critical, so I expect live quantity adjustments pushed instantly to connected users (SignalR or an equivalent WebSocket approach is fine). The workflow must also support barcode scanning from either handheld scanners or a device camera, immediately pulling up the matching SKU for fast check-in / check-out. Reporting and analytics round out the must-haves: dashboards that show current stock, low-level alerts, turnover rates and exportable PDF/CSV summaries. A straightforward filter/search experience should let me slice data by date ra...

My existing VB.NET project is behaving unpredictably: it sometimes crashes on startup and, even after it loads, other crashes appear at random. I need these bugs isolated and fixed so the application runs reliably every time it is launched and during normal use. You will receive the full Visual Studio solution and a short video showing the crashes in action. I have not added any custom logging yet, so incorporating meaningful exception handling or a lightweight logging mechanism is welcome if it helps trace the faults quickly. Deliverables • Corrected source code with clear comments on the changes • A brief summary explaining what caused each crash and how you resolved it • Simple reproducibility steps that confirm the issues no longer occur Please use standard VB...

I’m setting up a new e-commerce platform and want it architected as a collection of microservices. The core service I need first is a rock-solid Product Catalog: searchable, filterable, and ready to scale as the inventory grows. That means designing its own database schema, APIs, and admin endpoints while keeping the door open for companion services such as user authentication and a payment gateway that I may plug in later. Here’s how I picture the engagement: • You define the microservice structure, select appropriate tech (Node.js, Spring Boot, or another framework you’re comfortable with), and spin up a clean, container-ready codebase. • The Product Catalog must expose REST/GraphQL endpoints, handle basic CRUD plus bulk import/export, and support SKU-l...

I need a small, self-hosted OCR service written in C# (.NET 6 or later) that accepts a Base64-encoded image and instantly returns the recognised text. Tesseract must be the engine under the hood, configured for English only, with any preprocessing kept lightweight so the full request/response cycle stays in the low-millisecond range on a typical workstation. The DLL or minimal Web API you build has to be thread-safe so several parallel calls will not block each other. I’ll plug this straight into existing .NET applications, so please expose a clean public method or REST endpoint, document every parameter, and keep external dependencies to a minimum. Deliverables • Complete, well-commented source code and solution files • Build/run instructions and NuGet package li...

I built our freight-forwarding solution in .NET with an MS SQL back end, covering everything from enquiries and quotations through to job management, House BL printing, and P&L reporting. The only missing piece is a seamless bridge to external accounting software—this is where I need your expertise. What I want • Direct integration between my freight-forwarding database and a well-known accounting package (e.g., Tally, QuickBooks, Xero or a similar platform you can propose). • Automatic transfer of all financial events we already capture—sales invoices, supplier bills, receivables, payables, and cost allocations—so the books stay in sync without duplicate entry. • Bi-directional status updates: if an invoice is paid or a journal is adjusted in th...

Our large-scale application already runs smoothly on Angular with a .NET back end, but its interface lacks the polish our users expect. I want the entire front end re-skinned with a modern, minimalist theme that keeps every screen consistent wiht out any functionality change, introduces a refined colour palette, improves the layout hierarchy and tightens up the typography. You are free to recommend a high-quality commercial or open-source Angular theme; once we agree on the choice, you will handle full integration. That includes wiring its components into our existing modules, replacing current styles, and ensuring the new look stays responsive across desktop and mobile. A particular focus is the main dashboard: I need clean, interactive data-visualisation widgets (charts and graphs) tha...

I need a small, reliable service that sits between Busy Accounting Software (desktop) and my cloud-based ERP. The goal is simple: every time my ERP creates an invoice, payment voucher, credit note or debit note the same document must appear in Busy instantly—no manual export-import, no delays. My ERP already exposes a well-documented REST API and its data lives in MySQL. Your task is to read the new or updated records, apply the correct field mapping (most fields match one-to-one, but a handful will need custom logic for tax and cost-centre breakdowns) and then push the payload into Busy through the method you know best—SDK, XML import, ODBC or any proven Busy integration technique. Key expectations • Sub-second or near real-time sync for invoices, payment vouchers and...
