    I want every sales voucher leaving our system—whether it ends up printed or emailed—to carry the correct user-specific signature without anyone having to paste or sign manually. We issue both paper and digital vouchers, so the solution must handle both paths seamlessly. Here is the flow I’m after: once a user finalises a voucher, the system recognises who they are and drops in their signature automatically. For digital vouchers the signature can be a clean, typed representation of their name; for paper vouchers the same text should print in the signature area so the document is ready for filing or handing to the customer. You may connect this functionality to our existing voucher module, extend our print template, or introduce a lightweight middleware layer—whiche...

    I need a Windows-based quotation program tailored to our poultry-feed-mill manufacturing business. We build everything from complete feed mills to automation systems, grain-storage silos and feed-transport units, so the application has to let me create and save several product lines in one place, then pull them into a quote without re-typing anything. The heart of the job is a set of fully customizable templates. Each template must let me decide how Product details, a clear Pricing breakdown and Customer information appear, then lock those choices in for reuse. When a quote is ready, one click should render it as a neat, branded PDF that I can download or attach to an email outside the app. I’m comfortable if you use .NET, C# or another Windows-friendly stack, as long as the instal...

    I need a Windows-based tool that plays the Shipwrightery puzzle inside Puzzle Pirates to an “Incredible” rating every board. The core of the job is a C# script that reads the current board state, calculates the mathematically optimal next move, and shows that move on a small, simple interface I can leave open beside the game. Because I already know the game inside out, the algorithm has to be rock-solid: it must keep an internal timer, track streaks, update its board model after every click I make, and immediately refresh the suggestion so there is no visible lag. A lightweight WinForms or WPF front end is fine—clarity and speed matter more than fancy animations. Think coloured highlights or arrow overlays, not theme skins.

    I want to build a small, self-contained application that lets me place and manage equity trades from a single interface. At this stage I have not committed to any one platform or trading style, so I am happy to consider web, desktop, or mobile solutions and to refine the workflow together once we review your proposed stack and timeline. Core functions I need right away are: • Secure sign-in tied to my brokerage API • Real-time quotes and basic charting • Order entry for market, limit, and stop orders • A straightforward positions and P&L view If you have experience wiring APIs such as Interactive Brokers, Alpaca, TD Ameritrade, or similar, please highlight that, along with the language or framework you would prefer (for example Python with FastAPI, React + ...

    I’ve built the core of my basketball prototype in Unity 3D and now I’m ready to bring the on-court feel to life with realistic dribbling. The focus is exclusively on advanced dribble moves—crossovers, spin moves, and behind-the-back transitions—and I’d like them to chain smoothly so players can string combinations together on the fly. Here’s what I need from you: • A responsive dribble controller written in C# that plugs into my existing player controller. • Quality animations (or placeholders I can swap later) for each move, blended so there’s no foot-sliding or ball warping. • Input handling that feels natural on both keyboard/gamepad, including quick direction changes and move cancels. • Clean, commented code that I ...

    I am starting a new project that revolves around ASP .NET Core 8 (C# 12). The priority is pure backend work: designing and coding a robust API layer that will let intelligent agents plug into our existing business systems in real time. The heart of the job is the “connexion d’agents IA” aspect. You will be creating MCP-compliant services that expose context, receive agent actions, and safely persist results. While the immediate focus is this AI bridge, your code must stay clean and extensible so we can later hook the same backbone to front-end interfaces or even an eventual Sage 100 connector. To move forward I need a detailed project proposal outlining: • the architecture you would follow for an MCP server under ASP .NET Core 8 • the way you will secu...

    I need a patient, hands-on mentor to guide me through building a full Document Approval & Digital Signature solution while I learn Microsoft Power Apps from the ground up. I’m a beginner, so every step—planning the data in SharePoint Lists, wiring up flows in Power Automate, and designing a responsive Canvas App—has to be explained and demonstrated live, then repeated by me until I’m comfortable. We will start with Power Automate because I want to understand the backbone of the workflow first: dynamic approver selection, multi-level approvals, automated email notifications, and status tracking. Once the flows are solid, we’ll switch to the Canvas App to surface those same capabilities—focusing especially on dynamic approver pickers, live status indi...

    I already have the full source code for a desktop .NET application and I’m happy with its functionality, but it feels sluggish. What I’m looking for is a focused performance pass aimed purely at speed—no new features or bug-hunting, just making the existing code run faster. Right now the two problem spots are: • Data-intensive routines that slow to a crawl when large datasets are loaded or complex calculations run. • User-interface lag; controls hesitate and redraw slowly while those same heavy operations are happening. You’re free to suggest profiling tools such as Visual Studio Profiler, dotTrace, or PerfView; whatever pinpoints bottlenecks most effectively. Once identified, I’d like you to refactor the hotspots—algorithm tweaks, async/aw...

    I need a compact trading bot that plugs into Pocket Option, tracks my your strategy, and texts me the moment every condition lines up. The bot must monitor three data streams at once—price trends, a defined set of technical indicators, and live market news—then run its alignment check on a fixed five-minute loop. When all three pillars confirm the same direction, it should fire off an SMS alert to my phone instantly and reliably. Key points you’ll handle: • Direct integration with Pocket Option (API or web-automation, whichever is safest and within their terms). • Modular indicator engine so I can tweak or swap indicators later without rewriting the whole bot. • Lightweight news feed parser that can pull headlines or sentiment scores and feed them in...
