I am a Unity Developer and author of “Mastering Unity Game Development” with over 5 years of experience creating engaging 2D and 3D games across multiple platforms. I specialize in building gameplay systems, optimizing performance, and developing clean, maintainable code that scales. In my career, I’ve contributed to successful projects such as Climbing Sand Dune (20M+ downloads) where I boosted daily active users and revenue through new features and optimizations, and Nordhold, a roguelike tower defense game on Steam, where I worked on new gameplay mechanics, bug fixing, performance improvements, and UI enhancements. I have also collaborated with teams on various other genres, from mobile casual to multiplayer strategy. Key Skills: - Unity scripting, gameplay programming, and UI engineering - Systems architecture, rapid prototyping, and clean code principles - AI development (state behaviors, pathfinding, smarter enemy logic) - Networking & backend integration (REST APIs, PlayFab) - Advanced 3D math, physics, and optimization techniques - Mobile performance optimization across low-end devices I bring a comprehensive approach to game development from designing mechanics and improving user experience to solving performance challenges. Whether you need to enhance an existing project or build something new, I can help you bring your vision to life.

I am a Unity Game Developer specializing in action-heavy gameplay, intelligent AI, and high-performance optimization for both PC and mobile. Over my career, I have evolved from building core RPG mechanics to developing complex, highly optimized systems—bridging the gap between pure programming and technical art. I don’t just write code; I build complete, scalable game experiences. Whether it’s designing multi-phase boss fights, writing custom network logic for multiplayer, or modeling and animating assets from scratch in Blender, I focus on delivering buttery-smooth gameplay (targeting 60-120 FPS on mobile). Core Expertise: 1- Advanced Combat & AI: State-machine-driven enemy logic, complex attack behaviors, multi-phase boss fights, and Souls-like combat mechanics. 2- 3D Animation & Pipeline: Custom Blender modeling, rigging, and seamless animation integration (including root motion) directly into Unity. 3- Systems Architecture: Robust save systems, inventory management, player progression, and modular C# frameworks designed to scale. 4- Performance Optimization: Deep mobile optimization, memory management, and maintaining high frame rates across low-end and high-end hardware. Featured Portfolio Projects: 1- Mobile Action RPG (Recent): A high-performance, Souls-like mobile game featuring advanced enemy AI, complex boss encounters, and a custom 3D art pipeline. Engineered specifically for flawless mobile performance without sacrificing visual fidelity. 2- Real-Time Multiplayer Survival: A fully networked mobile survival game demonstrating strict performance optimization, real-time multiplayer synchronization, and robust server-client architecture. 3- Narrative Top-Down RPG: A systems-heavy PC RPG showcasing foundational architecture, including custom save/load serialization, quest logic, and core combat loops. 💡 My Approach: I write clean, modular, and highly optimized code. I treat every freelance project as if it were my own game, ensuring the final product is not only functional but highly polished and easy for other developers to expand upon. Whether you need a complete combat system built from scratch, a multiplayer backend, or advanced AI to bring your enemies to life, let’s discuss how I can elevate your project. 🚀

With 9+ years of game-development experience, a 100% Job Success Score, Top Rated status, $20K+ earned, and 600+ Upwork hours, I can join an existing project, understand its architecture quickly, identify technical risks, and deliver maintainable solutions. Selected Unreal Engine experience: • Online multiplayer, replication, sessions, lobbies, matchmaking, and reconnection flows • Epic Online Services and PlayFab integration • C++ and Blueprint gameplay architecture • Gameplay Ability System, locomotion, interaction, and combat systems • AI using Behavior Trees, EQS, navigation, and custom systems • Performance profiling, debugging, optimization, and project stabilization • Procedural animation, Control Rig, physics, and animation integration • Windows, Linux, macOS, VR, iOS, and Android development Recent work includes a long-term EOS and PlayFab lobby-system integration, multiplayer development for Glizzy Royale, and serving as Multiplayer Lead Programmer on Katana Inu. When contacting me, please include: • Your Unreal Engine version • Target platforms • The system or problem you need solved • Whether the project uses C++, Blueprints, or both • Any relevant screenshots, videos, logs, or technical documentation I will review the requirements and recommend the most practical next step.

Senior Unity/C# developer (5+ yrs) specializing in real-time multiplayer, live-ops backends, and VR/XR. Top Rated, 100% Job Success, 50+ projects delivered. I recently shipped C# gameplay and full Arabic RTL localization for Football Manager 2026 at Sports Interactive (SEGA) — a AAA franchise built on a 100+ developer Perforce pipeline. On the product side, I built Block Battle Online, a 1v1 real-time multiplayer game (Unity + Photon Fusion + PlayFab) with 50,000+ downloads, a 4.7★ rating, and 700+ reviews. If you need multiplayer that holds up under load, a backend that scales, or a VR prototype that runs at 90 FPS on Quest, that's the core of what I do: • Multiplayer / netcode: Photon Fusion 2 (Shared & Host/Client modes), FishNet, Mirror — matchmaking, lag comp, state sync, authority • Backend / live-ops: PlayFab (Azure Gaming BaaS), Azure Functions, Firebase, AWS — leaderboards, tournaments, virtual currencies, CloudScript • VR/XR: Meta Quest 2/3, VRIF, XR Interaction Toolkit — I shipped an enterprise VR training app demoed at GISEC Dubai 2024 • Mobile & WebGL: Unity IAP, AdMob, cross-platform optimization; a game-based learning WebGL platform for Rutgers University; 3 self-published titles at 22K+ combined downloads • Arabic RTL localization: production-grade RTL via Unity UI Toolkit / TextMeshPro — a genuinely hard problem I've solved at AAA scale Credentials: BSc (Hons) Computer Science, University of Greenwich (UK) / MSA Cairo; AWS Certified Cloud Practitioner; IBM IoT/AI/Cloud badges. I also run a small studio, Mind Invaders Games, so I can scale from a solo contract to a small delivery team when a project needs it. I write clean, documented, production-grade C#, communicate in clear English, and ship on schedule. Whether it's a fixed-scope feature (add multiplayer, wire up PlayFab, localize to Arabic) or full-cycle development, I'll give you a straight estimate and hit it. Send me a message with your build and your goal — I'll reply with a concrete plan and timeline.
