.NET Jobs

I’m preparing a bespoke digital project (internally referenced as “zek23145f78”) and I need an experienced developer who can guide the build from concept to launch. The core idea is defined, but I’m still refining key details such as whether we’ll deliver it as a web app, mobile solution, or cross-platform desktop tool. Because of that, I’m looking for someone comfortable discussing options, recommending the best tech stack, and then executing the agreed-upon plan. Here’s what I need from you: • An initial consultation where we walk through my objectives, target users, and any constraints I might not have surfaced yet. • A concise technical proposal that outlines architecture, timeline, and milestones. • Development, testing, a...

I need an experienced software engineer to design, code, and package a Windows-only desktop application whose core purpose is to boost user productivity. The interface should feel modern yet lightweight, launching quickly and remaining unobtrusive while running in the background. You will take the project from concept to final installer, including UI/UX design, core feature implementation, local data storage, and basic update handling. Please choose the language and framework you are most comfortable with on Windows (for example C#, .NET 6/7, WPF, WinUI 3, Electron, or another proven stack) and explain why it is the best fit for maintainability and performance. Key deliverables • Compiled executable and a click-through installer that works on Windows 10 and 11 • Complet...

I’m ready to streamline my small office, starting with document management. The priority is a system that can automatically file every incoming document, allow my team to edit or collaborate on those files in real time, and then archive them for fast, reliable retrieval later. Beyond the core workflow, I want lightweight AI woven in to handle automated tagging and categorisation so files surface instantly when we search or trigger downstream processes. If your preferred stack already includes smart search or data-extraction modules, let me know—those could be next on the roadmap once the first phase proves itself. What I need from you: • Design or recommend the best-fit platform (SharePoint, Google Workspace, Notion, dedicated DMS—open to options). • Config...

I need senior full-stack developers who can prove a substantial open-source record—specifically at least 300 merged pull requests on GitHub under your own name. The work spans web, mobile, and desktop initiatives, so versatility is key. The active tech stack includes JavaScript/TypeScript, Python, Java, .NET, Rust, and Go. Depth in two or more of those languages is mandatory because projects move quickly and switch contexts often. Share your Github repos that has over 300 + PR's and ensure no AI code are used and only human written code is written. Deliverables • Clean, well-tested code merged via GitHub PRs • Concise commit messages and inline documentation • Regular participation in review discussions Acceptance criteria • CI pipelines pass...

I need a seasoned .NET backend developer to build a suite of RESTful APIs that will power our next release. The core of the job is pure API development—no UI work—so you should feel completely at home writing clean, well-structured C# code in .NET (preferably .NET 6 or later), wiring it up with Entity Framework or Dapper for data access, and documenting everything with Swagger / OpenAPI. Here’s what the APIs must handle: • User authentication (token-based, ideally JWT) • Full CRUD operations for our primary data models • Smooth third-party integrations, starting with two vendors that expose JSON endpoints I’ll provide the database schema, access credentials, and a concise list of integration endpoints on kickoff. You’ll return: 1. So...

My production C# application currently targets .NET Framework 4.8 and has started to show its age. I need it migrated to a supported, more secure runtime (ideally the latest LTS release of .NET), with every dependency updated and any obsolete APIs refactored. The primary driver is security: I want all outstanding vulnerabilities removed, HTTPS enforcement tightened, and modern authentication/cryptography practices adopted throughout the codebase. During the upgrade I also want to introduce a clean integration layer so the app can talk to external systems (REST and, if feasible, simple message-queue endpoints). This should be implemented in a way that keeps the core logic decoupled and unit-testable. Finally, a handful of persistent UI glitches—visual misalignments and sporadic cont...

I’m ready to move my Paying-Guest/hostel operations off spreadsheets and into a single, web-based platform built with .NET (C#), SQL Server or MySQL, HTML, CSS and JavaScript. The application will sit on a hybrid setup—part cloud, part on-prem—so clean separation of concerns and a painless deploy script are important. Core scope • Secure, role-based authentication for Owners, Students and Administrators, each landing on a tailored dashboard. • Property and room management with live availability, quick search and filters. • Student self-registration followed by a guided room-booking flow that updates availability in real time. • Integrated rent ledger: capture payments, show history, flag overdue amounts and let me export or print offline recei...

I run a combined warehousing and steel fabrication operation and I need a dedicated desktop application (MS Excel) that lets us schedule production efficiently. The tool must install and run reliably on both macOS and Windows machines and I’m aiming to have a first usable release as soon as possible. At a minimum the scheduler should let us: • input the difference machines and their respective production rates • set up different production methodologies • create and edit production jobs in a calendar or Gantt-style view • forecast delivery and expenses depending on manpower, shift schedules, and workdays • assign work centres, crews, or machines to each job • track inventory or raw-material availability and usage • produce simple status or ...

I need an experienced engineer who can take ownership of a large-scale, long-term product built around a .NET 8 / ASP.NET Core backend and a React.js + TypeScript frontend. Your first focus will be refining and extending our existing API layer, modelling new features, optimising performance, and making sure every endpoint is production-ready. Once the backend foundations are solid, you’ll move fluidly into the React codebase—building reusable components, wiring state with modern hooks, and ensuring the UX feels instant even when we lean on complex business logic. We already run in AWS, so you should be comfortable deploying microservices and event-driven workflows with containers (Docker) orchestrated through Kubernetes and managed via standard CI/CD pipelines. The infras...

I’m adding a “one-click” PDF-to-Excel feature to my website and need an executable that can take any uploaded bank statement in PDF form and return a clean, well-structured XLSX file for the user to download. At this stage I’m not tied to specific bank templates—the tool should handle common layouts gracefully and be easy to extend later if we decide to fine-tune it for particular institutions. Because the service will be open to everyone who lands on the page, stability, speed, and simple error handling are crucial. Visitors will not log in; they will just drop a file, hit convert, and immediately receive the spreadsheet, so there’s no room for lengthy queues or time-outs. Here’s how I picture the workflow: 1. User uploads PDF via the web inte...

I need a self-contained desktop application that lets our transport office see every vehicle in the fleet at a glance, schedule and log each service, record fines as they occur and plan future availability. A web portal or mobile extension could follow later, yet the first milestone must be a solid Windows desktop build that runs smoothly on ordinary office PCs. Core functionality • Live or near-real-time vehicle tracking tied to each registration number so the map, status panel and reports always agree. • A maintenance calendar that warns us before inspections or services are due and locks vehicles that overrun, with a history tab for parts, labour and cost. • A fines module where staff can enter penalties, attach scans/photos and track payment status, with quick fil...

I’m ready to stand up a full-featured Customer SOP library in Microsoft SharePoint Online and need someone who can take it from blank site to production-ready. The finished space must let the team store and organise every SOP, co-author drafts in real time, then route each document through a formal approval flow that ends with an automatically generated PDF published for end-users. Here is what I expect to see when we’re done: • A clean document library with a well-planned metadata schema (content type or columns) and a handful of saved views that surface the right SOPs by status, owner, effective date, review frequency and any other tags we finalise together. • A master SOP template in Word stored centrally so new documents inherit the right layout and metadata...

I’m looking for an experienced IT professional who can jump in quickly and resolve a Windows-based software-installation problem for me. The application fails to complete its setup on a Windows 10 workstation and I need clear, actionable help to get it running without errors. Here is what I expect: • A live session (Zoom, Teams, or similar) or secure remote-desktop connection so you can diagnose the root cause. • Step-by-step fixes applied during the session, covering prerequisites, permissions, registry edits or command-line work if necessary. • A brief recap at the end—what you changed and how to repeat the process should I reinstall in the future. If you routinely troubleshoot Windows installers, handle dependency issues, and are comfortable with tools like ...

I want to build a full-stack desktop application that enables pharmacists in my store to manage daily operations from a single, intuitive interface. The core modules I need are: • Inventory management that keeps real-time stock levels, tracks expiry dates, and provides low-stock alerts. • Prescription handling with quick patient lookup, doctor information capture, and automated interaction checks. • Sales reporting that summarises daily and monthly revenue, highlights best-selling medicines, and exports to CSV or PDF. The entire workflow—from receiving a prescription to final sale—has to feel seamless on a desktop computer, so performance and an offline-friendly architecture are important. A clean UI/UX, role-based access, and straightforward installation o...

Pharmacy Management System – Full-Stack Web Application I developed a complete Pharmacy Management System designed to help pharmacies efficiently manage their daily operations, inventory, sales, purchases, and financial activities.

Key Features: • Dashboard with pharmacy statistics and business overview • Medicine and product management • Categories management • Inventory and stock management • Expiry date tracking • Low-stock alerts • Supplier management • Purchase management • Sales and Point of Sale (POS) • Customer management &...

We have an enterprise-grade Angular 19 code-base running in Azure that now needs to be spun into a brand-new mobile-first application containing only a subset of key features. Alongside the front-end work, the server side is expected to run on .NET 8, so clean API design and modern C# patterns are part of the scope. Here is what I need from you: • Own the build: clone the existing repository, set up a fresh solution for the trimmed-down app, and keep everything wired through our Azure Repos, Azure DevOps pipelines, and Azure App Service. • Translate my high-level requirements into detailed estimates, sprint plans, and milestones; I rely on you to manage this process end-to-end. • Implement the identified features (we will finalise the list together) using Angular 19 be...

I need a ready-to-deploy POS application for my restaurant that runs natively on Windows laptops and touchscreen terminals. The core job is to deliver a billing system that lets staff enter orders quickly, split or merge checks, apply discounts and taxes, and print receipts without lag. Table control is essential. I want an on-screen floor plan where hosts can see open, occupied, or reserved tables at a glance, create new reservations, and assign them to servers. The interface should switch seamlessly between touch input on a kiosk screen and keyboard/mouse on back-office machines. Speed, stability, and an intuitive layout matter more to me than a long list of peripheral modules. Inventory tracking or employee scheduling can stay out of scope for now; what I really care about is rock-sol...
