Before vs After 👇 Started with a basic placeholder — ended with a fullscreen 3D G63 you can rotate, change paint color, and view in cinematic camera shots. What's under the hood: → Real-time inventory synced from Telegram → Fullscreen interactive 3D model with 7 cinematic shots → Auto-cycling paint colors every 30 seconds → Multi-image photo galleries on every listing → Auto-detects phone numbers & contacts from listings → TikTok video section with raw embeds → Full car detail pages with image carousel Built with: Node.js · Express · Google model-viewer · GSAP · Three.js · Cheerio Real Cars ETH — premium auto dealership, Addis Ababa 🇪🇹 Before vs After 👇

Why drop in a 3rd-party package when you can engineer the engine? I had a standard Flutter YouTube package sitting right there. One dependency. Seven lines of boilerplate. I could have shipped it and gone to bed. Instead, I went down to the bare metal. I spent my nights engineering Aura Trinity—a sovereign media ingestion and compositing engine built directly from raw bitstreams. 4 languages. 3 layers. 0 external SDKs. 📊 The Numbers: • 16 concurrent live streams composited simultaneously without a single dropped frame • 512-stream architecture built for carrier-grade ingestion density • Hardware-accelerated pipeline: 100% transcode offload to the NVIDIA GPU via CUVID / NVENC ⚙️ The Technical Trinity: 🦀 Rust (The Network Core): High-throughput async I/O handling 512 concurrent TCP/UDP sockets with Tokio. Zero leaks, zero runtime overhead. ⚙️ C++ (The Bitstream Engine): Direct FFI interop walking raw H.264 NAL units and executing bitstream-level forensic watermarking directly in the DCT domain. 🌐 Node.js (The Edge Ingestion): A diskless proxy intercepting dynamic N-signatures through direct V8 memory piping to eliminate 403 Forbidden throttling at scale. Most packages give you a feature. Architecture gives you absolute control and leverage. I chose the architecture. 🎯 Currently exploring high-impact roles in Systems Architecture, Distributed Video Infrastructure, and Performance Engineering. 🔗 Deep-dive docs & architecture diagrams: • Framework: [Link] • Systems Architecture: [Link] (Links also pinned in the comments below) #SystemsEngineering #Rust #CPP #CUDA #FFmpeg #MediaStreaming #PerformanceEngineering #DistributedSystems #LowLevel

Mobile AI shouldn't just talk. It should ACT. ⚡ Here is a 1-minute demo of an autonomous mobile agent I built: 🔹 Converts natural language instructions into multi-step execution plans 🔹 Interacts with native Android apps (Settings, Chrome, etc.) 🔹 Identifies UI elements dynamically and handles taps, swipes, and text input hands-free Built with Python, LLMs, and on-device UI perception. If you're building agentic AI, mobile automations, or looking to collaborate, my DMs are open! 🚀 #AI #MachineLearning #AIAgents #Python #AndroidDev #Automation
