    My son wants to play the PC game “Football Player,” but the download is tucked away behind a multi-part archive on an external site. I already have the direct link; what I need is someone who can: • Grab the full set of game files from that link • Safely extract and re-package them into a single, clean installer or folder that runs on Windows • Send back the ready-to-play files (or a verified cloud link) along with brief notes on anything I should know—extra DLLs, run-as-admin steps, or antivirus flags that might pop up If you normally use WinRAR, 7-Zip, or similar tools, that’s perfect. Just be sure the final result launches without errors on a standard Windows 10/11 machine. Please let me know roughly how long you’ll need once you recei...

    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 need a fully-coded Relative Strength Index indicator that plugs straight into Quantower via its open API. The core requirement is simple: the look-back period must be user-adjustable from the platform’s settings panel so I (or any trader) can fine-tune it on the chart without opening the source. Please keep the script lightweight, coded in C# as recommended by Quantower, and use the platform’s standard drawing and event hooks so it behaves exactly like a native study—automatic repaint on bar close, proper scaling on sub-panes, and settings persistence between sessions.

    I already run my content calendar across several social- and blog-channels and now want the entire publishing chain handled automatically through Make (formerly Integromat). Together we’ll map the exact workflow, but at a high level I need a scenario that can: • Pull fresh copy, images, and short clips generated by ChatGPT, Google AI, or IBM Watson—choosing the best tool per step. • Re-format that content on the fly (proper aspect ratios, text length, metadata, alt tags). • Publish simultaneously to the social networks and blogging platform accounts I’ll share with you. • Return clear logs plus error notifications in Slack or email so nothing slips through the cracks. what I’m missing is the Make scenario(s) and any helper scripts that g...

    I need a seasoned NinjaTrader coder to turn my trading ideas into fully functional components on the platform. While I’m still refining the exact mix of custom indicators, automated strategies, and possible data-feed integrations, the immediate priority is clean, efficient NinjaScript that can be compiled and deployed without hassles on both live and simulation accounts. 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. Clear in-code comments are a must so I can tweak parameters down the road. For hand-off, I expect: • The finished .cs file(s) ready to import. • A brief outline of param...

    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 need a standalone desktop program that lets me analyse horse races by pulling fresh horse-performance data directly from www.racenet.com.au. The application’s single job is to automate that scrape, store the information locally, then give me an interface where I can filter and compare runners so I can make better decisions before each meet. Key workflow • Scrape horse performance data (form, distance, track conditions, times, margins, etc.) from the public pages on whenever I hit “update”. • Save everything to a local database so I can work offline once the sync is done. • Surface simple analytics—speed ratings, last-start comparisons, track/distance strike rates, and any other insights you can compute reliably from the scraped fields. &bu...

    I need a Windows-based desktop program that follows each sofa, chair, or table we build from the moment it is sold right through to the truck leaving our dock. The flow should start with order entry, automatically raise the fabric purchase request, then guide the piece through cutting, frame-building, upholstery, packaging, and finally shipping. At every stage I want a clear status board and simple way to update progress so the whole team can see what is waiting, what is in work, and what is finished. A small local SQL database is fine as long as it scales to a few dozen simultaneous users; if you prefer another lightweight option, mention it and why. The interface must be straightforward—touch-friendly for the shop floor, keyboard-driven in the office—so staff can scan a barc...

    Necesito un pequeño software hecho a medida que instale y funcione sin complicaciones en Windows. Trabajo como Masajista y Terapeuta Gestalt y hoy llevo mis registros en hojas sueltas y un par de hojas de cálculo; busco concentrar todo en una única aplicación ligera, clara y en español. El núcleo debe ser una ficha de cliente con su historial completo de sesiones (fecha, tipo de tratamiento, notas rápidas). Desde la misma pantalla quiero poder registrar el cobro, generar una factura en PDF y, si lo deseo, programar un recordatorio automático para la próxima cita (correo, SMS o cualquier integración sencilla que me propongas). También me interesa un pequeño panel estadístico con los tres datos q...

    Role: Software Developer / Technical Partner (Equity Opportunity) I am looking for an experienced software developer to join me as a technical partner on the development of an AI-integrated desktop application, from MVP through to initial launch. This is not a contract-only role. For the right person, there is an opportunity to take on a meaningful equity stake, reflecting long-term involvement in architecture, implementation, and product evolution. The product is a stateful, non-trivial application that integrates AI as an interactive system component. It requires careful data modelling consistency management, and thoughtful UX for extended use. This is not a marketing website or a thin wrapper around an API. Core requirements: Experience building desktop applications (Electron, Tauri, ....
