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.

    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 have an ESP32 based product that should maintain a steady Wi-Fi link, yet on my home network it keeps dropping off and taking too long to re-associate.

    My small business already runs on Gmail, Chat, Docs, Sheets, Slides and Calendar, yet the mix of consumer versus business accounts and a growing email load (10+ messages a week and climbing) leaves the workflow scattered and privacy settings uncertain. What I need is a clean, well-documented Workspace configuration that respects data-sharing comfort levels while letting every tool work together smoothly. Here is what success looks like for me: • A concise audit of the current accounts that spells out where consumer logins can stay and where a business tier would be smarter. • Step-by-step configuration of Gmail (labels, filters, signature, templates), shared Drive folders, Chat spaces and Calendar sharing so the team can collaborate without chasing links. • Privacy an...

    I’m looking for a QA Engineer who can join our Madurai team on a six-month contract and bring 3–4 years of solid quality-assurance experience to the table. Manual testing is the day-to-day backbone of the assignment, and I also need someone confident enough with automation to build and maintain suites that keep regression runs tight and reliable. You’ll collaborate closely with developers and product owners in our office, owning the full test cycle—from writing clear test plans to validating production fixes. If you already script with Selenium or a comparable framework, you’ll ramp up fast; if you have wider performance-testing exposure, that’s a welcome bonus but not essential. Key deliverables during the contract: • Comprehensive test plans...

    Fix Entra ID Teams Bug
    Ending left
    Verified

    I spun up a brand-new Azure Entra ID tenant and installed/used that tenant on my local machine. Ever since doing so, Microsoft Teams desktop refuses to load. The client gets stuck on the splash screen and then consistently throws the same sign-in error on every attempt. No other Microsoft 365 desktop apps (Word, Excel, Outlook, etc.) appear to be affected, which strongly suggests the issue is isolated to Teams authentication and/or licensing, likely stemming from Entra ID or Teams-related configuration applied during the tenant setup and sign-in on this machine. I’m looking for someone who can jump straight into the Entra admin portal (and, if useful, PowerShell and/or the Teams Admin Center) to trace the Teams sign-in flow, identify the misconfiguration, and apply the fix so the T...

    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...
