⚙️ AI Infra & C++ 20 Embedded Systems Journey

---

🎯 Project Purpose

This repository tracks my professional upskilling roadmap:

• Technical Expertise in Modern C++ 20/23 and to align with the current design trend.
• Master Embedded & RTOS development using Zephyr and ARM Cortex-M.
• Master the Design & innovation skills to create great products
• Build a solid base for AI Infrastructure — C++ systems + Python ML stack.
• Maintain a public GitHub portfolio for interviews (target Holi 2026).

🧭 Upcoming Roadmap

📘 Phase 1 ( Oct – Dec 2025 )

C++ 20 Mastery + Zephyr RTOS Setup

• Design Patterns in Modern C++
• Advanced C++ 20 features (ranges · concepts · coroutines · modules basics)
• Zephyr RTOS basics → threads · GPIO · timers · QEMU runs
• ARM Cortex-M architecture overview (ready for Pi 5 + Pico)

📗 Phase 2 ( Jan – Feb 2026 )

Embedded Integration + RTOS Design

• Memory management · ISR · multi-thread design patterns
• Build automation for Zephyr apps + GTest mocks
• Simple device drivers & peripherals (LED, UART)
• Mini project: RTOS Task Scheduler Demo on QEMU then Pi Pico

📙 Phase 3 ( Mar – May 2026 )

AI Infra Bridge

• Python–C++ interoperability (PyBind11)
• Data pipelines + ONNX Runtime demo
• Micro AI on Embedded (TinyML concepts)
• GitHub polish + mock interviews (DSA + System Design + Embedded)
