    I’m putting together a brand-new game in Unreal Engine and need an experienced developer to help me take it from concept to a polished PC release. The core responsibilities will revolve around building gameplay systems, integrating assets, and packaging stable Windows builds. I already have a general vision and art direction; what I’m missing is the technical expertise to transform those ideas into a smooth, responsive experience. You should be fully comfortable with Unreal Engine (Blueprints and/or C++), know your way around performance optimisation for desktop hardware, and be able to advise on best practices for input handling, networking, and QA workflows.

    I want an app that scans the phone’s camera roll, recognises the same person across different shots, and then lets me decide exactly which images to forward. The core flow is simple: • First, the app analyses every photo, clusters faces that it believes belong to the same individual and shows me those groupings. • From there, I can pick pictures one-by-one or bulk-select them in three distinct ways: individually, by date range, or by geolocation. This mirrors the way I already think about my library, so the interface needs to surface those three filters prominently and let me combine them if I wish. • Once I have a final selection, the app should open the standard share sheet so I can send the chosen files through any installed channel (Messages, WhatsApp, AirDrop...

Think World of Warcraft’s third-person feel, but stripped down to the essentials—no progression, inventory, or persistent accounts.

    I need our current project, built in Unity 4, migrated cleanly to Unity 6 while keeping the game exactly as players know it. The core work is twofold: first, bring every gameplay mechanic over so it runs flawlessly on the newer engine flow on the latest UI toolkit. No new features are required; this is a straight upgrade focused on compatibility, stability, and a polished feel in the updated environment. I expect you to handle any API changes, package replacements, shader or lighting tweaks, and input-system updates that Unity 6 now enforces. Final delivery is the upgraded Unity 6 project folder ready to open, build, and release version. In this time run in android, need to work with Windows and WebGL too.

    # MMORPG Game Client Reverse Engineering - Anti-Cheat Bypass ## Project Description We operate a private server for an MMORPG game. The game client is written in C++ (Win32, DirectX 9, x86) and uses XignCode3 as its anti-cheat system. We have a complete C++ GameServer and a custom Launcher. We need a reverse engineer to update our existing client hook DLL to work with the current game client version. The anti-cheat addresses have changed in the latest client update, and our hook DLL needs to be updated accordingly. This is for private server development, not cheating on official servers. ## What We Need 1. Analyze the current game client EXE using IDA Pro with Hex-Rays decompiler 2. Find all XignCode3 bypass addresses in the new client (LoadLibrary calls, init functions, timer callba...

    أعمل على لعبة كرة قدم أركيد جديدة بعنوان "الإسماعيلي بطل" موجهة لأجهزة Android (5.0 فما فوق) وبحجم لا يتجاوز ‎100 MB. الفكرة بسيطة ومباشرة: يتحكم اللاعب في نجم الإسماعيلي داخل ملعب الإسماعيلية، يسجل الأهداف، تزداد سرعته، ويتخطى العقبات والأعداء مع تقدّم المستوى. لدينا ثلاث درجات صعوبة، وأهداف زمنية واضحة (على سبيل المثال: إحراز 5 أهداف في 30 ثانية). التركيز الأكبر في هذا التنفيذ سيكون على تصميم الشخصيات؛ أرغب في نماذج ثلاثية الأبعاد واقعية للاعبي الإسماعيلي الحاليين مع إمكانية تخصيصها للمستخدم (تغيير المظهر، الأطقم، وربما الاحتفالات بعد التسجيل). أحتاج أن تبدو الوجوه مألوفة لجمهور النادي، لكن في الوقت نفسه يجب أن تعمل بسلاسة داخل بيئة أركيد خفيفة. إلى جانب الشخصيات، يلزم ضبط فيزياء الكرة والحركة، بناء نظام ترقية المهارات، وإضافة موسيقى حماسية تعكس أجواء استاد الإسماعيلية من...

    My current site already runs on Angular 21, but several persistent bugs are hurting the user experience and a few fresh features are overdue. I’m looking for an Angular specialist who can dive straight into the existing codebase, resolve those glitches, and then extend the app with the new functionality I have planned. Here’s what I need you to handle: • Identify and squash the reported bugs so there are no unexpected console errors or broken flows. • Build the new features I’ll outline during our kick-off call, following the project’s current coding standards (TypeScript, RxJS, Angular CLI, SCSS). • Leave the code cleaner than you found it—unit tests updated, comments clear, and lint warnings at zero. All work will be reviewed on a featur...

    I'm seeking an experienced C++ developer to write a patch for an old Windows 98/XP game to make it stable on Windows 10. The game currently crashes or freezes during gameplay, seemingly at random after playing for a while. The game is designed for 32bit, not 16, so it should probably be a bit easier.

    I’m building an internal business tool and need an experienced .NET Core developer who can work during the India night shift (roughly 9 PM–5 AM IST). The project centers on a browser-based web application, so you’ll spend most of your time inside ASP.NET Core, Entity Framework, and SQL Server, wiring up clean MVC or Razor Pages, setting up dependency injection, and testing endpoints with Postman or Swagger. You’ll collaborate directly with me over Teams for quick stand-ups and code reviews, pushing updates to a Git repository each night. I already have wireframes, a partial domain model, and an Azure DevOps board with user stories ready for you; your first tasks will involve refining the data layer, implementing responsive views, and tightening up API endpoints. D...
