From 192,546 reviews, clients rate our .NET Developers 4.9 out of 5 stars.I need an experienced .NET and Blazor developer who can give my product a full-time focus—eight hours a day ,starting asap —while working side-by-side with my lead engineer during Indian Standard Time. The codebase is already in production; our goal over the coming weeks is to tidy up rough edges, harden performance, and keep new issues from sneaking in as we roll out incremental updates. Tech stack you’ll touch daily: ASP.NET Core APIs, a Blazor front end that leans on hooks and functional components, JSON-heavy data exchange, and Azure resources provisioned with Bicep. You’ll be handling pull requests, writing clean commits, and jumping on quick Teams or Slack calls whenever a change needs clarification. Expect a straightforward workflow—branch, code, PR, r...
I need a browser-based system that lets me run every aspect of our carpark from any Windows PC without installing extra software. The core of the build is flexible customer handling: I must be able to set up and manage short-term, long-term and annual accounts with independent pricing, expiry rules and access limits. For customers who park “on account”, the system has to trigger an automatic email on the 20th of each month containing their balance and payment link, so scheduling and SMTP integration are essential. A live dashboard should surface the three key metrics I use to steer the business—revenue, customer-usage statistics and occupancy rates—with the option to export each report to CSV or PDF. Drilling down into any figure should reveal the underlying tra...
I have a C# application that is now locked behind WinLicense + Themida 3.x. My only goal is to regain access to the project so I can open it in Visual Studio and continue working on it. I do not need a ready-to-run executable; what I’m after is clean, compilable source code. Once unpacked, I want to see: • the full user-interface layout and resources, • the core functionality and algorithms, and • all data-processing and storage routines. A straightforward Visual Studio solution (.sln, .csproj, assets, references) with clear build instructions will be considered a complete delivery. If any sections remain obfuscated, please document the reasons and suggest next steps.
I need assistance installing Visual Studio 2022 on Windows 11 and creating an MSI installer for it. I am a Visual Basic developer, but have hit a problem creating an installer and would like some assistance/guidance. I recently updated the application to use Nuget packages and Net 8.0 and am struggling getting the dlls to install correctly. The VS installation creator is picking up the wrong sql server and system dlls. The application includes two extensions, Component One and DevExpress I suspect the problem might be because the extensions are using different versions of the system and sql server dlls. Is this something you can help with please? Requirements: - Create an MSI installer for the setup of a desktop application Ideal Skills: - Experience with Visual Studio 2022 and Ne...
I run a project with a large-scale, custom integration to SAP S/4 HANA and now need an expert who knows the Sales and Distribution area inside out. The technical landscape already includes an extensive C# service layer that exchanges data with S/4, so the ideal partner is comfortable discussing both functional SD scenarios and how they translate into .NET code and APIs. Your main focus will be to examine my current SD setup, identify any gaps or mis-alignments with best practice, and guide me through the right configuration or enhancements. Whether the issue lies in pricing, order processing, delivery scheduling, or billing flows, I want pragmatic recommendations I can apply immediately and, when needed, hands-on help inside the system. Experience with the relevant SAP tools—SPRO,...
My donation-counter application (VB.NET, ASP.NET, SQL Server) currently treats the day as four 6-hour shifts. I need the underlying logic switched to three 8-hour shifts—nothing else about the feature set is changing and the screens can stay exactly as they are. Core work • Rework the scheduling code so every function that references shift boundaries now recognises 00:00-07:59, 08:00-15:59 and 16:00-23:59 (or equivalent server-time logic). • Update the existing SQL reports and any stored procedures that aggregate by shift so their totals align with the new 8-hour blocks. Acceptance I’ll verify by running a full day’s test data: the counters must roll over at the new cut-off times and all daily/shift reports must balance against those timestamps. This ...
I have an in-house VB.NET application backed by SQL Server 2008 R2 that currently schedules four 6-hour shifts per day. Operational changes now require three 8-hour shifts instead. The change touches two main areas: • Business logic – all routines that build the daily roster, assign staff and calculate shift boundaries work off the 4 × 6 model. • Database structure – several tables store fixed shift identifiers, start / end times, and downstream references that assume four records per day. Because the scheduling and allocation algorithms drive time-sensitive workflows, any adjustment must keep existing calculation accuracy intact. The user interface itself can stay as is; only back-end logic and schema need attention. What I need delivered 1. Updated ...
I’m moving our freight-invoice workflow off a Windows-only desktop utility and into a fully SQL Server–driven pipeline. All business rules live in clear documentation, every data source has been mapped, and I have a year’s worth of validated invoices to prove the expected outputs. Here is the flow I need implemented: CSV files arrive from carriers, they are ingested into staging tables, T-SQL stored procedures match each line to the appropriate rate-card logic, the correct freight charges are calculated, and the results are surfaced through an API. The API’s main purpose is to let our client application migrate data and trigger the stored-procedure processing as needed. To keep us aligned, these are the concrete deliverables: • Schema for raw, staging, and ...
Dear Partners, I am currently seeking a fully functional, production-ready white-label neo-banking SaaS platform that can be rapidly deployed and customized with our branding (logo, colors, visual identity).

I need a Windows-only desktop application tied to a web-based LMS portal. The core of the job is to let learners access course content on a single, registered machine and to keep that content safe from capture. Key points • Single-device login: once a user signs in with their username and password, the licence is bound to that computer. Any attempt to log in elsewhere must be blocked automatically. • Screen-capture defence: the moment a screen-recording or screenshot tool is detected, the learning window should turn blank until the activity stops. • Course management tools are required inside the LMS so I can upload, organise and retire modules, monitor enrolments and push updates to the desktop client seamlessly. Deliverables 1. Windows desktop client (installer + sou...

I need my existing VB.NET application (currently locked to a three-shift pattern) adapted to run four distinct shifts per day while keeping everything our staff already know intact. What must stay the same • The original shift times and their duration logic • All employee assignment and roster rules • The look, layout and structure of our current reports What must now be flexible • Shift schedules: start and end times should be editable from the UI • Report parameters: date range, department, and any other filters must be user-selectable Reports required • Daily Shift Summary • Shift Attendance Scope of work • Refactor VB.NET code, UI and business rules to recognise a fourth shift without breaking historical data • ...
I’ve just purchased a new Windows computer and need all my existing content moved across—roughly 200 GB made up of standard documents, office files, and a collection of photos and videos. Both machines run Windows, so the job is a like-for-like transfer with no OS conversion headaches. What I need from you: • Prepare the new PC so it is ready for everyday use (user account, basic preferences, folder structure, network connection). • Copy every file exactly as it sits on the old machine, keeping the same hierarchy so I can find everything instantly. • Verify that all 200 GB arrives intact—no corrupt images, no missing Word docs—before wrapping up. No additional software installation is required; I’m handling Office and any specialty apps later....

I’m overhauling a growing startup’s ASP.NET Core codebase and I need another set of expert hands. The immediate focus is to simplify and clean up the API layer, with special attention to the database-interaction code. We are on SQL Server, hosted in Azure, and wired into Azure DevOps for CI/CD, so solid experience across that stack is essential. Beyond the back-end work, you should feel comfortable dipping into the HTML and lightweight UI touches that surface in our Razor pages. The first milestone is to rebuild the authentication portion of the API; once that is stable we will iterate through the remaining endpoints. To make sure we are a good fit, I’ll start you on a contained trial task. Let me know: • Your hourly rate • The number of hours you can commi...
I’m looking for an experienced M-Files developer based in India to join us remotely for an initial 3–6 month engagement, with the option to extend if the collaboration goes well. Primary objective • Build and refine API integrations that connect M-Files to our CRM platform. (We already handle basic workflows and configuration in-house; your main mission is clean, reliable data exchange between the two systems.) Day-to-day expectations • Analyse our current M-Files vault structure and CRM data model. • Design the integration flow, mapping objects and metadata appropriately. • Develop .NET/C# code that leverages the M-Files API and the CRM’s REST/SDK endpoints. • Implement secure authentication and robust error handling. • Docum...
I need a clean, well-structured ASP.NET REST service that processes static infrastructure data stored in a SQL database. The service must expose endpoints to create, read, update and delete the records, returning JSON throughout. Key points • Technology stack: ASP.NET (Core preferred) with Entity Framework (Code First or Database First—use what lets you move fastest) and Microsoft SQL Server. • Data model: a small set of tables representing our infrastructure items; I will supply the exact fields once we start, but plan for typical ID, name, location and status columns. • Endpoints: /items (GET list, POST create), /items/{id} (GET, PUT, DELETE) plus any helper routes you feel are useful. • Processing rules: basic validation (unique names, non-null locat...
I’m building a REST-based .NET API dedicated to policy management for an Indian insurance platform. The immediate scope is twofold: enabling seamless policy creation and automating renewals, all while exchanging customer data with our existing CRM system in real time. You’ll be working in C# on .NET 6/7, applying clean-architecture patterns, Entity Framework (SQL Server), and secure OAuth2/JWT authentication. Because this sits inside an IRDA-regulated environment, I expect production-ready logging, error handling, and audit trails that match standard compliance practices in the Indian market. A minimum of three years’ hands-on experience delivering insurance solutions in India is essential—you should already understand typical policy lifecycles, endorsement logic,...
I have an idea for a Windows-only desktop application and I’m looking for a software developer who can turn that concept into a working program. At this stage I will share the core functionality and user-flow privately, then rely on you to: • Translate my requirements into a clear technical plan • Build a clean, responsive GUI using a modern Windows-friendly framework (for example, C#/.NET or similar—open to your recommendation) • Package the finished solution with an installer so end-users can set it up easily • Provide source code, brief build instructions, and a short user guide Code must run smoothly on current Windows versions and follow standard best practices for error handling and maintainability. If you have experience integrating local da...
I am building 630792Dooro as a dedicated software application for e-commerce and need a solid, production-ready shopping cart coded from the ground up. The app will not run inside a browser; it should be a standalone desktop or server-side application (you can suggest the stack you feel is most reliable for this use case). Core objective • Design and implement a secure, scalable shopping cart that can handle item selection, quantity updates, discount codes, tax and shipping calculations, and checkout hand-off to a payment gateway. What you will deliver • Source code with clear, commented logic • Database schema or ORM models for cart persistence • Simple UI mock-ups or wireframes demonstrating cart flow • A short README explaining setup and build st...
I need my BUSY Accounting Software quotation print-out turned into a three-part PDF that is produced with a single click inside BUSY’s Sales Quotation screen. Here is the exact flow I am after: • Part 1 – the standard sales-quotation layout that already ships with BUSY (no visual changes). • Part 2 – an extra page that the user populates on the fly with up to four project images or drawings. Each image must accept a short title; when the quotation is printed or exported, those four titled images should be auto-arranged on a single portrait page. • Part 3 – an existing “clients list” PDF that resides in a fixed location and must be appended automatically. When the user chooses Print or Export to PDF, BUSY should silently merge Parts ...
I’m building a production-ready web application on ASP.NET Core and need a seasoned C# engineer to accelerate the backend and UI layers. The project already has a clean architectural outline; what I’m missing is expert-level implementation that ties everything together smoothly. Core scope • Secure user authentication and role-based access (ASP.NET Core Identity). • Robust data-processing routines that read, transform, and persist large datasets via Entity Framework Core and SQL Server. • Interactive reporting and dashboard views with concise visualisations; or any comparable library is fine as long as the end result is responsive and exports cleanly to PDF/Excel. Your tasks will include wiring up the authentication flow, designing efficient EF Core mode...
