.NET Jobs

I have a Windows-based productivity desktop application that is almost ready for release, and I need a detailed, functionality-focused review. The assignment is straightforward: install the app on a Windows 10 or 11 machine, use every feature as an everyday user would, and record exactly how each function behaves. I’m interested only in what the app does and whether it does it correctly—visual polish and performance metrics are outside this scope. Please pay close attention to workflow logic, data handling, error messages, and how well edge-cases are managed. If you spot anything confusing, missing, or broken, capture it with a screenshot or short screen recording. Deliverables I need from you: • A succinct issue log with severity or priority tags • Clear steps to...

The project is an ASP.NET Core web application backed by MS SQL Server. I already have the base solution set up and connected to the database; what I need now is an advanced .NET developer who can push the codebase forward, polish architecture decisions, and keep everything aligned with the most recent ASP.NET Core best practices. Front-end pages are rendered with Angular and, in a few feature areas, Vue components, so you’ll occasionally collaborate with the UI layer and make sure the API contracts remain clean and stable. Key areas I want you to focus on: • New feature implementation in C#, ASP.NET Core, and Entity Framework Core • RESTful API design and integration with existing Angular/Vue views • Query optimisation and indexing on MS SQL Server, including p...

I need a Windows desktop application written in C#/.NET that faithfully reproduces the behaviour of my current software—yet there is no documentation or source code to reference. Your first milestone will involve analysing the existing executable, mapping out its logic, and rebuilding the same core flow from scratch, including all API interactions that keep the program functional. Once parity is reached, I want a handful of bespoke improvements folded in before moving on to Phase 2: a secure, browser-based admin panel that lets me manage users, licensing, and configuration parameters remotely. The admin back end can be built with the stack you are most comfortable with so long as it integrates cleanly with the desktop client and follows solid authentication practices. Deliverab...

Tengo una aplicación de escritorio compleja desarrollada en .NET MAUI. La versión Windows funciona correctamente y no debe modificarse, pero la versión compilada con Mac Catalyst presenta fallos que impiden su uso profesional en macOS.

Requisitos imprescindibles - Español hablado fluido - Disponibilidad inmediata (esta semana o, como muy tarde, la próxima) - Dedicación de 30–40 horas semanales - Trabajo directo sobre el código ...

I’m a YouTuber who wants immediate, practical coaching while I’m recording or live-streaming. The goal is a desktop application that lets me pick any connected microphone and camera, sends the live feed to Gemini (or the most effective alternative you recommend), and listens for moments where I can improve myself for the rhythms or anything else, listener-friendly rhythm. When that happens, the app should break could speak to me so I can correct myself on the spot. I work on both macOS and Windows. So I’ll let you decide what is the best. I’m happy with an Electron wrapper, a native Swift + .NET pair, or any framework you believe will keep latency low; just outline why you think it’s the best route. If the Gemini Live API is not yet public or stable, feel fr...

I need an ASP.NET Web API that external partners can safely call to create, read, update, and delete transactional data. The service will sit in front of an existing external database, so the project covers building the endpoints and wiring them to that data source through Entity Framework (or another lightweight ORM if you can justify the choice). I’m interested in a clean REST-style design, proper HTTP status use, and solid exception handling so third-party developers can integrate without surprises. Key deliverables: • Fully functional ASP.NET Web API project targeting .NET 6 or later • CRUD endpoints for all transactional entities mapped to the external database • Token-based authentication and role-based authorization • Swagger / OpenAPI docs generat...

I’m building a custom ASP.NET MVC web application whose centerpiece is an interactive dashboard. The dashboard must surface key metrics with clear visualisations and allow me to drill down, filter and export data-driven insights on demand. Custom report generation is critical: users need to click a button and receive a professionally formatted PDF powered by the iTextSharp library. Your job is to wire up the MVC project, design the views and controllers for the analytics area, and integrate iTextSharp so the same data that feeds the on-screen charts can also be compiled into downloadable reports. I already have a SQL Server schema in place; you’ll connect to it via Entity Framework (Code First or Database First is fine) and shape the queries that drive both the dashboard wid...

I need an AI-driven workflow that starts with raw Excel workbooks and ends with ready-to-present Power BI-embedded PowerPoint files. At its core, the agent must take over repetitive data-entry chores—copying and pasting data between sheets, applying consistent cell formatting, and generating the routine summary reports I currently build by hand. Once the spreadsheets are in shape, the same pipeline should feed that refreshed data straight into Power BI, refresh the visuals, and export the updated dashboards as slides. Here is what I expect to receive: • An autonomous script, service, or low-code bot that opens designated Excel templates, performs the three data-entry tasks above without human clicks, and logs every step for traceability. • Automated refresh of the linke...

I run a live production app that combines a .NET 8 microservice back-end with a React Native front end, hosted on Ubuntu servers in AWS. Right now the most urgent need is to deliver new functionality, and nearly all of that work sits squarely on the back end. Your first assignments will centre on extending our microservice architecture and exposing new, well-documented APIs. You’ll be writing C#, containerising services, wiring events through RabbitMQ, and persisting data in PostgreSQL—then shipping the code straight into production. I pay $6/hour for hands-on development only; time spent reading code, researching, or experimenting is on the freelancer. Work independently, own your tasks, communicate clearly, and suggest improvements when you see them. Do that well and there&r...

I’m building a cross-platform social media application that will let users create rich profiles, chat in real time, and scroll an algorithm-driven news feed. The front end is planned in React; on the server side I’m open to Python (FastAPI or Django), .NET, or Java—whichever lets you deliver clean, well-documented RESTful APIs quickly. Beyond the core features, I want to embed an AI-powered chatbot that can handle basic customer-support questions inside the app. If you already work with frameworks such as TensorFlow, PyTorch, or Azure Cognitive Services, that experience will be valuable. I’ll handle UI mock-ups and brand assets; you’ll translate them into responsive components, wire them to the backend, and integrate the chatbot so it feels native. I pre...

I need a Windows-compatible desktop application built from scratch. At this stage the concept is defined at a high level, so I’m ready to discuss use-cases, UI flow, and the most suitable tech stack—whether that ends up being .NET, C#, C++, or another approach you can justify. Here’s what I expect once we agree on specifications: the compiled installer, well-commented source code, and a concise setup/user guide so I can maintain or extend the program later. Clean architecture, clear documentation, and timely progress updates are important to me, and I’m happy to iterate quickly through milestones to keep everything on track. If you have a strong background in Windows software development and can walk me through the best way to turn the requirements into a reliable...

I want a lightweight Gen-AI application that lets me write a plain-language prompt and instantly receive a fully populated Autodesk Civil 3D site plan. The generated drawing must respect standard Civil 3D objects and styles and include road-design elements such as intersections, roundabouts, and complete drainage systems exactly as described in the prompt. The flow I’m after is simple: I type something like “Create a 500 m collector road with two T-intersections, one central roundabout, and a curb-and-gutter drainage network that ties into the existing surface,” press enter, and Civil 3D builds the geometry for me. No manual drawing—everything should appear as polylines, alignments, corridors, surfaces, and pipe networks ready for refinement. Core expectations &...

I'm operating a care home service in Sweden, currently housing six clients who permanently reside in my establishment. I am not interested in the existing systems on the market, as they are prohibitively expensive and do not meet my needs effectively. They lack integration, proper development, and adherence to standards. What I require is a tailored system for my clients that includes the following features: 1. Implementation Plan: For each of the six clients, the system should cover nine different life areas (such as communication, health, daily life, free time, etc.). Each life area should define a goal, specify WHAT actions need to be taken, identify WHEN these actions should occur, and designate WHO will be responsible for them and HOW. 2. Documentation: This feature will allow...

I’m looking to have a full-featured point-of-sale application built for Windows PCs that I can distribute to my own clients. They will install it locally, enjoy a 3-month free trial, and then move automatically to a paid monthly subscription, so licence management has to be baked in from day one. The user must be able to tailor three key areas on their own—interface layout, report generation, and inventory management—without calling a developer each time. Within the sales screen the software should accept Credit/Debit Cards, Mobile Payments, and Cash, storing each transaction type separately for reporting purposes. What I need from you: • An installer for Windows that runs cleanly on standard PC-based POS hardware • A licensing / activation module that start...

I need a flow in Microsoft Power Automate that pulls KPI values from our SQL Server tables and turns them into polished, user-friendly PDF reports. The report must rely on a custom-designed template and display information with a mixture of charts, graphs, and tables so non-technical stakeholders can grasp trends at a glance. Our priority metrics revolve around operational efficiency—think throughput, cycle time, and utilisation—so the layout should spotlight those numbers first while still letting me expand to other KPIs later. The ideal solution lets me choose a date range (or other common filters) and then either schedule or trigger the report on demand. Once generated, the PDF should save to SharePoint and email key managers automatically. I am comfortable giving you read ...

I need a desktop application built exclusively for Windows that streamlines our vehicle turnover process.

First, I want the data layer to communicate with external accounting services through a REST-style API. The module should issue authenticated HTTP requests using only the methods I plan to expose—GET, POST and PUT—to push or pull records between the database and providers such as InFakt or Betterfly. I expect clean, asynchronous calls via HttpClient (or another modern .NET approach), clear error handling and concise helper classes that make future endpoint additions straightforward. Second, the system must generate invoice exports. When I select ‘Faktury’ in the UI, the code should collect the relevant rows and create XML files that fully respect the FA(3) KSeF structure. The output has to validate against the official XSD so that I can upload it to KSeF without ...

I’m assembling a small, dedicated team of developers who can commit full-time hours to building and maintaining desktop applications. Your day-to-day will revolve around new feature development, refactoring legacy code, squashing bugs, and collaborating closely with me on release planning and UX improvements. Because the role focuses on desktop‐grade performance and cross-platform reliability, hands-on experience shipping production-ready Windows, macOS, or Linux apps is essential. I’m flexible on the specific language or framework you prefer—whether you thrive with Electron, .NET, Qt, JavaFX, or another stack, what matters most is that you can demonstrate polished, stable executables and a solid engineering process.

I need a Windows-only desktop application that streamlines my day-to-day data analysis work. At minimum the utility should let me import common formats such as CSV or Excel, inspect and filter the records, run simple statistical summaries (mean, median, standard deviation, counts), and export the results. Clean visualisations—basic line, bar and scatter plots—would be ideal so I can spot trends quickly without jumping to another tool. Responsiveness matters more than flashy UI; native Windows frameworks (WPF, WinForms, Electron, Qt—whichever you are comfortable with) are all acceptable as long as the final build runs smoothly on Windows 10 and 11 without additional installs. I’ll also need the complete, well-commented source code and a brief user guide so future tw...
