Z Secret — Mobile E-Learning & Training Academy Platform 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

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.

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! 🚀
