I run a home-grown virtual tabletop simulation and would like to replace the handful of spreadsheets and manual clicks with one cohesive Windows desktop app. The goal is to automate three core areas: resource management, combat resolution, and the various turn-by-turn trackers that keep the session running smoothly. The interface needs to be an intuitive GUI—think drag-and-drop character panes, quick-access buttons for initiative, real-time stat bars, and a clean dashboard where I can toggle optional house-rules on the fly. Under the hood, I need solid data handling so that hit points, spell slots, cooldowns, and inventory stay in sync even when multiple NPCs are involved. If a player swings a sword, I want the dice rolled, modifiers applied, and results logged to the history panel ...

My ASP .NET website loads fine until the moment a user logs in—right after pressing the Login button an error message pops up and the page stops there. I can capture and share a screenshot of the exact message, but I don’t have the text copied out. Nothing else needs to be clicked for the issue to appear; it happens instantly after authentication. I’m looking for someone willing to troubleshoot this one-off problem pro bono. You’ll have temporary access to the project files or a zipped copy (C#, .NET Framework, SQL Server back-end) so you can replicate and patch the fault. Once you identify the cause and supply the fix—whether it’s a tweak, an authentication middleware adjustment, or a code-behind patch—I’ll implement it on the live serve...

I need a lightweight .NET MAUI mobile application that targets Android and contains only three screens: • Login – users choose Face ID/biometrics, an NFC badge tap, or a numeric PIN to sign in. • WebView – after authentication the app simply embeds a URL that I will provide at build time. • Admin – a management screen (hidden behind its own sign-in) where I can add or edit users, assign permissions, and tweak basic app settings. All data, including user credentials, roles and configuration, must live in a MySQL database accessed through a secure REST API that you will craft and integrate. Please separate API, data-access and front-end layers cleanly and keep the code in MVVM pattern. C#, .NET 8, Entity Framework (or Dapper), Visual Studio and standard...

I already have a web-based EHR written in .NET that stalled before launch. The core workflows are in place, yet three areas still block us from going live: • Bug fixing (top priority): the current build shows several UI/UX inconsistencies, a handful of security gaps around authentication/authorization, and broken FHIR calls that return empty payloads or 500 errors. • FHIR integration: the R4 endpoints exist but half of the resources are unmapped and the conformance statement fails validation. . I need someone who has shipped an EHR or similar health-tech product, is comfortable working in C#, ASP.NET Core, Entity Framework, and knows the HL7 FHIR spec inside out. Familiarity with ONC certification criteria—USCDI data classes, SMART on FHIR launch, etc.—will make...

I’m looking for a developer who can turn SharePoint Online into a secure image library where every single photo is automatically bound to a verified informed-consent record. The aim is strict compliance and traceability, not public display. The solution must recognise three role‐based audiences: Administrators, Compliance Officers and Regular Users. Administrators need the ability to manage user roles, audit consent records and approve or revoke access in real time. Compliance Officers must be able to audit those records as well, monitor actual image usage across the site and generate exportable compliance reports. Regular Users simply add, search and use images—but only within the permissions that the linked consent allows. Core expectations • When a user uploads an i...

I need a hands-on full-stack developer who can own both the C#/ASP.NET Core back-end and a React front-end. The immediate focus is to build, test, and maintain a scalable web application that cleanly separates concerns yet feels seamless to the end user. On the server side you’ll architect RESTful endpoints with ASP.NET Core Web API, wire them to MS SQL Server, and keep performance in check through efficient queries and thoughtful caching. On the client side you’ll create reusable React components, manage state responsibly, and make sure the UI stays snappy across modern browsers. I expect clean, well-documented code, meaningful unit tests, and proactive communication when a requirement needs clarification. Collaboration is part of the daily routine: you will coordinate with ...

I am building a fully-featured social networking platform from the ground up and need a developer who can own both the server-side and front-end work. The stack is set: C# ASP.NET (Core preferred) powered by an MS-SQL database. Scope of work You’ll start by architecting the database, spinning up the ASP.NET project, and exposing a clean, well-documented REST (or GraphQL, if you prefer) API. Identity-based authentication, role management, and token-based security need to be wired in from day one. Key features I must see at launch: • Messaging system (asynchronous and real-time) • News feed with post, comment, like, and share capabilities • Private chat using SignalR or an equivalent WebSocket solution • Meeting scheduling module that lets users create, ...

I need an experienced .NET and React developer who can give my product a full-time focus—eight hours a day for the next month—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 React 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, ...

I’m building a Windows desktop application and need someone who already feels at home in the full .NET ecosystem—C#, WinForms or WPF, Entity Framework, and modern async patterns. The work covers the entire cycle: architecture decisions, coding, UI polish, thorough testing, and packaging for deployment on current Windows versions. I’ll share the functional outline and existing mock-ups as soon as we connect; clean, well-commented code and brief setup notes will serve as the final deliverables, alongside the signed installer. If you’ve shipped at least one production-grade desktop app in .NET and can point me to it, we can get started right away.

I want a Blazor WebAssembly application that my team can run entirely in the browser while still taking advantage of .NET on the back end. The project’s focus is an internal business app, so security, speed, and a clean code-base are more important to me than public-facing design polish. Core features I need working from day one: • User authentication – sign-in, sign-out, role-based access, and token refresh handled with ASP.NET Core Identity or another proven library. • Data visualization – interactive charts and tables (think , Plotly, or the built-in Telerik/Syncfusion components if you prefer) driven by live data pulled from our existing APIs. • File uploads – drag-and-drop or standard picker that writes to a secure storage endpoint, then d...

Our perinatal care application runs on the classic .NET Framework with an MVC architecture over a MySQL data store. The current print-friendly forms for the patient’s perinatal history are only half wired: the controller does not yet retrieve every field we need and the Razor templates themselves need several small layout tweaks. The assignment is to: • extend the existing controller so every relevant perinatal-history field is queried from MySQL, mapped to the correct view model, and passed to the view • refresh the print templates (we already have them, they just need updates) so the output matches the supplied layout exactly, including headers, footers, and page breaks • run through enough test cases to prove data integrity and visual consistency across common...

I am completing a capstone project that must showcase end-to-end work inside Power BI. The source data sits in SQL Server and is modest in size—well under 10 k rows—so performance tuning will centre on clean Query Folding rather than heavy aggregation tricks. Here is what I need done: • Connect Power BI to the SQL Server instance through Power Query, document each step, and keep every transformation foldable. • Shape and load the tables, then model them with the correct many-to-many relationship where required. Please do this in the Model view so the links are visually clear. • Create essential DAX measures—CALCULATE(), RELATED(), and any supporting columns you find helpful—so the model answers typical summary and slice-and-dice questions. &bu...

I have an Ubuntu server ready for production and a custom domain that is already registered. The stack running on that machine is a React front-end, a Python API, and Mongodb for data storage. What I’m missing is the final wiring that turns all of this into a publicly reachable, secure site. Here’s what I expect as concrete deliverables: 1. Install Python and setup api to accessible remotely 2. Install Node JS and React and setup domain and run required npm install ensure site is accessible with SSL 3.

Concept I am seeking to take a Trading View strategy utilizing the Lux Algo Fair Value Gaps on NAS100 (NASDAQ CFD) on a 3 minute chart, ultimately automating the execution at speed to precision with a C Trader bot. The reason for this is pertaining to the fact that there is a severe latency delay in data being received from broker to Trading View, then to generate a signal and execute this on a 3 minute chart is not possible to do in sync. Secondly, following a traumatic death of my dad, my emotional state has simply not been in the right place to execute my strategy without breaking the rules in one way or another. Therefore there is a need to automate things and remove the emotional aspect to trading, whilst the robot will also only ever follow the rules. With regard to the indicator c...

The immediate milestone is to stand up a fully-functional DocuSign environment inside our C# / ASP.NET Core platform. Within that integration I need three things working seamlessly: • each template must pull the correct rates and monetary values into every field, • document workflows have to fire automatically from creation through signature, and • the whole flow must hook into our existing system endpoints without manual intervention. Because no formal documentation for those rates and values exists, you and I will map the data together, define the XML schema that will carry the information, and wire that schema to the DocuSign API. Once the DocuSign piece is solid we can move on to the wider XML-driven automation logic and, finally, a performance-oriented redesig...

I have a C# Blazor Server web application that runs unattended in several kiosks. From this app I must be able to push invoices, reports, stickers and small queue tokens straight to the locally-attached printer without stopping for a browser dialog. The ideal workflow is: • the user clicks “Print” inside the Blazor page • the job is routed to the default printer (thermal and A4 models are both in use) • if required, a quick print preview can be shown inside the app • the document leaves the printer immediately, with no system pop-ups or confirmation windows I am looking for someone who has demonstrable experience implementing silent printing in Blazor or similar web stacks (Javascript interop, WebAssembly, raw ESC/POS or Microsoft Print Document AP...

I have an ASP.NET Core 9 API up and running on my Windows development machine. The next step is to serve responses from the Ollama Phi3 language model through that API, leveraging an NVIDIA GPU so inference remains fast even under load, and then publish the service so it can be reached publicly from anywhere in the world. Here is what I need: • Configure the Ollama Phi3 model to run on an NVIDIA card (CUDA already installed). • Wire the model into my existing controllers so endpoints stay unchanged for consumers but now call the GPU-accelerated Phi3 instance behind the scenes. • Package everything for production—Docker is fine if it simplifies deployment, but a native Windows service is equally acceptable. • Provide brief, step-by-step documentation so fut...

I need an engineer who has spent at least five years building production software with both .NET Framework and .NET Core. The stack you will step into combines C#, ASP.NET Web API, Entity Framework and SQL Server on the backend, served through RESTful endpoints and a growing set of microservices. The frontend is split between Angular and ReactJS, so confidence working in either framework—and switching when the codebase demands it—is essential. You will work fully remote but must overlap with Indian Standard Time for stand-ups and ad-hoc discussions. Strong verbal and written communication is therefore just as important as your coding skills, because you will often be the one making technical decisions independently. The first milestones include extending existing APIs, migrat...

I want a complete, desktop-based Hospital Management System that lets me register patients, schedule appointments, manage both OPD and IPD workflows, and produce clean invoices in a single click. The application must run locally on Windows and keep its own database so the hospital can continue working even if the internet is down. Alongside the desktop app I need a small online CRM whose sole focus is software licensing. It should: • Generate unique license keys automatically • Let me allocate those keys to Distributors and, in turn, to their Retailers • Show real-time activation / expiry status so I can disable or extend keys remotely Both parts should share a consistent tech stack (C#, Java, or any mainstream framework you are comfortable maintaining) and follow sta...

I need a skilled developer to build a brand-new desktop application for the technology sector. The goal is to take the idea from concept to a working installable program, complete with clean, well-commented source code. The core scope includes: • Architecture design and technology stack recommendation (I’m open to .NET, Java, Electron, or another framework you feel best fits). • Implementation of the main features and a responsive desktop UI. • Basic data persistence—local database or file storage, whichever suits the design. • Setup script or installer so users can get up and running quickly. • Concise user documentation and a brief hand-over session so I can maintain the app after delivery. Key things I value are clear communication, regular...

I’m building a complete MCA-compliant XBRL filing solution that takes a company’s financial data all the way from spreadsheet import to final submission on the MCA portal. The application must: • Import and export data seamlessly to and from common spreadsheet formats so finance teams can keep using Excel without re-keying figures. • Validate every tag against the latest MCA taxonomy, catching errors long before the upload stage. • Generate human-readable reports (PDF or HTML) alongside the XBRL instance so directors can review what will actually be filed. • Operate both as an installable Windows desktop client and as a browser-based interface served from the same code-base, sharing logic wherever possible. • Log straight into the MCA porta...

I need a lightweight Windows-only .exe that lets me draw directly on the screen while any application is running. The main interface can be a slim sidebar with the classic whiteboard controls—pen (with adjustable size and colour), highlighter, eraser, hand/pan tool, plus undo and redo. Two extra features round it out: • An Import button so I can pull external files straight onto the canvas. I’m open to whichever formats are easiest to implement first; images and PDFs would cover most of my use cases, and we can expand later if it’s straightforward. • A built-in “Open Browser” command. I just need a full browser window to appear inside the app; I haven’t fixed on Chrome, Edge, or Firefox, so use whichever engine integrates cleanly and kee...

I’m looking for a standalone Windows desktop application that takes a set of repetitive tasks off my hands and runs them automatically at the click of a button (or on a schedule I can set). This first version is strictly for Windows, though having an architecture that could be ported to macOS or Linux later would be a welcome bonus. You’ll receive a detailed step-by-step outline of the processes I want automated. I’m flexible on the tech stack—C#/.NET, Python with PyInstaller, or any framework you’re confident will produce a clean, single-installer experience—but the end result must be a lightweight .exe with no cumbersome dependencies. Core expectations • A minimal, intuitive UI for inputting paths, parameters, and schedule options • Rel...

EUA INGLES I use Fan Control software daily to manage my PC's fan speeds, but I'd like to control one or more fans without having to open the program every time. I want simple keyboard shortcuts (for example, Fn + PgUp to increase RPM and Fn + PgDn to decrease RPM) that adjust the fan speeds (either as a group or a specific fan) directly, without opening the Fan Control graphical interface.
