Embedded Systems — Hardware, Firmware, Low-level Software

👋 Hi, I'm Elias

Embedded Systems Developer

Building systems from hardware to firmware.

⚙ What I Build

🔧 MCU Firmware

Firmware for 8051/STC and Cortex-M platforms, from register configuration to interrupt-driven control.

⚡ Peripheral Drivers

GPIO, timers, UART, I²C, SPI, ADC, DMA, display, storage, and sensor interfaces.

🧠 Embedded Systems

Hardware-aware software organized around resource maps, driver boundaries, task scheduling, IPC, and resource synchronization.
