    Stealth Windows Screen-Share Tool

    I need a custom-built screen-sharing application for Windows that feels as seamless as TeamViewer or AnyDesk but remains persistent even if the host user tries to remove or disable it. The service must install itself as a background process, automatically launch at every system start-up, and quietly reconnect without any manual action. Core capabilities I expect • Full remote-control of the host PC, including keyboard and mouse input, with smooth, real-time streaming. • Secure file transfer in both directions. • Single sign-on authentication so my team can log in with our existing identity provider rather than juggling extra passwords. Please focus only on Windows for the first release; 32- and 64-bit compatibility is required. Strong encryption, minimal latency, and...

    Real-Time Instagram 3D Trend Mapping

    I want to get up to speed on visualising Instagram hashtag activity as an interactive 3D network that updates in real time, so I can explore how clusters of conversation form and evolve. Basic counts or static charts won’t help me—I’m after a high-level, spatial overview that reveals relationships between hashtags at a glance. Here’s what I have in mind. You share your screen (or meet in a recorded call) and walk me through a streamlined pipeline: pulling public hashtag data from Instagram’s API or another compliant endpoint, streaming it into Python or Node, then projecting it with a WebGL or scene—Unity, Blender, or similar is fine if that’s your preferred stack. The goal is clarity over polish: I want to see each step, understand the code, and...

I will supply the trading logic, preferred time-frames, and any edge cases I’ve already identified; you translate that into robust code, add thoughtful error handling, and deliver a compiled script together with the editable source.

    I need a single piece of software that controls my dimension-weight-scanning workflow from start to finish. The application must talk directly to three devices on the line—scale, volumetric camera and scanner—capture the dimension and weight data, then trigger a photo of the package label. From that image the program should reliably pull out the text, barcode and any QR code in one pass. Once each package is processed, all results have to be written to an XML file structured by date, with an auto-incremented package ID embedded in the node. The same data set should immediately feed two more actions: 1. Generate a ready-to-print shipping label (standard 4x6 thermal format). 2. Push the full XML payload to our in-house system through a REST-style API. I expect the software t...

    I am building an intrusion-detection system that relies on entropy-based calculations applied over time windows to flag anomalous behaviour in user activity data. The goal is to detect subtle, previously unseen patterns rather than match against known signatures, so the core of the work is an efficient entropy engine that continuously ingests, time-stamps, and scores each event stream for deviation.

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 already have a working Flex Tool for vanilla Revit that reads a duct-to-grille pick, sizes the flex, and drops in the correct spigot. Since our workflows have moved to Revit Fabrication, I now need that same speed and accuracy inside the fabrication environment. Here is what I expect you to deliver: • Auto-size the flex run from the two picked points on the fabrication duct and the grille connector. • Place the spigot automatically at that location. • If the duct is too flat for the required diameter, select an oval spigot from our existing library and place it instead. • Tie the whole process into the fabrication database so part numbers, materials and sizes come through cleanly and schedules stay correct. • Provide the advanced material and size selec...

    .NET Core React Web Application -- 3

    Βεβαιωμένο

    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 ...

    Project Overview We are building an Excel-based automation and reporting system to track execution progress and speed across two parallel workflows: Listing optimization: - PPC advertising pipeline - The system must show status, velocity, bottlenecks, and readiness on ASIN and Cluster level, both internally and client-facing. This is a system-level automation project, not a simple dashboard. What the System Must Do: At any time, the reporting must clearly answer: - Where do we stand overall? - Which clusters are blocked or slow? - How fast is execution moving? - Is Listing or PPC the bottleneck? - How has progress changed vs yesterday / last week / last month? Core Scope (High-Level): - Derive execution statuses from raw Excel data - Track daily historical snapshots (append-only) - Cal...

    Windows Desktop App Development

    I’m looking for an experienced developer who can take my concept and turn it into a polished Windows desktop application. At this stage the focus is strictly on the Windows environment, so familiarity with tools such as Visual Studio, .NET (WPF or WinForms), C++/MFC, or other proven Windows frameworks is essential. The scope will cover everything from refining requirements with me through to coding, UI design, testing, and delivery of a ready-to-install executable. Clean, well-commented source code and brief user documentation should accompany the final build so I can maintain or extend the software later. Deliverables: • Production-ready Windows installer • Complete source code in a Git-friendly structure • Short setup/usage guide I value clear communic...

    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...
