I'm Sourabh Patyal, an Embedded Systems Engineer and Technical Trainer from 🇮🇳 India.
With a passion for bare-metal logic and a mission to mentor future engineers, I dive deep into microcontroller programming, hardware protocols, and system-level design.
🧠 “I don’t just blink LEDs — I light up understanding.”
- 🛠️ Bare-metal C – No HAL, no layers — just you and the silicon
- 🧾 Datasheet Diver – Registers don’t scare me, they guide me
- ⚡ Bitwise Thinker – Every bit has a story
- 🧵 Interrupt Sculptor – Precision ISR designs
- 🧠 Debugging Mentor – Find it. Fix it. Learn it.
