Hire the Best Qgiv Specialists

Hi! I am a graphic designer and developer. I've worked on Blender pipeline automatization, scripting and addons for the past +10 years. My experience includes parametric modelling, custom nodes systems, automated rendering and support for custom file formats. Over the years, I’ve also worked on web design, 3D modelling/lighting, and more recently mobile development. While user interfaces have always been my passion and focus, I’ve also worked on backends such as HTTP/WebSocket servers, geometric algorithms for 3D processing/generations, as well as glue code for libraries. I consider myself a quick learner and fast to adapt.

If your 3D model is going into a configurator, I already know what can go wrong before it reaches the browser. I build product assets for runtime control from the start: clean components, predictable materials, optimized GLB/glTF files, and a structure developers can actually work with. I prepare 3D products for component switching, material variations, tiled textures, configurable options, animation, and real-time use. My main focus is furniture, products, technical objects, vehicles, interiors, and other hard-surface assets for Web, AR, VR, e-commerce, and interactive product configurators. I understand the entire life of a configurable 3D product - from geometry in Blender to the customer clicking options in the browser. I also work with React and Three.js, which helps me understand both sides of the pipeline: how the asset should be built and how it will be controlled at runtime. My work includes: - 3D product modeling - GLB/glTF preparation - low-poly and mid-poly optimization - clean topology and UVs - PBR materials and texturing - scan and CAD cleanup - configurable component structure - material and product variants - real-time and web optimization 3D: Blender, 3ds Max, Substance Painter, Photoshop Web 3D: Three.js, React, WebGL Formats: GLB/glTF, FBX, OBJ and other production formats If you already have a model, CAD file, scan, drawings, or product references, send them along with the target platform. I can help prepare the asset correctly from the start.

I build production-ready Android apps that don’t just look good—they work reliably, sync in real-time, and scale with your business. I help businesses transform complex ideas into fully functional, high-performance mobile products. By combining Kotlin and Jetpack Compose with robust backend integration, I deliver apps that are ready for the Play Store—not just prototypes. ✅ Modern Android Development • Build fluid, responsive UIs using Jetpack Compose and Material 3 guidelines. • Implement scalable Clean Architecture (MVVM) and Hilt (Dependency Injection) for maintainable code. • Full RTL (Arabic) support and localization for the Middle Eastern market. ✅ AI & Intelligent Automation • Seamlessly integrate Google Gemini AI for intelligent health insights, chat assistants, and data analysis. • Implement automated data extraction using OCR (ML Kit & Tesseract) for National ID verification and document processing. ✅ Real-Time Sync & Business Logic • Design robust data layers with Firebase (RTDB, Firestore) and Room for a seamless local-to-cloud experience. • Architect role-based access systems (Owner/Admin/Staff) and QR-based authentication for secure operations. 💡 Proven Business Impact: • Dar Masr (Charity Management): Built and deployed a multi-branch system currently operating in 2 live branches. Digitized a 100% paper-based system into a real-time synchronized environment. • Se7ti AI (Health Companion): Developed a comprehensive 7-module platform integrating Gemini AI for anomaly detection and intelligent health tracking. • Logistics & Reporting: Built automated Google Sheets API pipelines to eliminate manual branch reporting for organizational leads. If your current app is buggy, outdated, or just an idea on paper, I will build a robust solution with precision and strategy. 🗓 Let’s connect to discuss your Android project or AI integration today.
