I specialize in low-level, register-level development (Bare Metal) and firmware optimization for ARM Cortex-M, AVR, and STM8 microcontrollers. I focus on writing highly efficient, non-blocking peripheral drivers, wireless telemetry systems, and creating custom automation tools to streamline the development workflow.

• STMicroelectronics: STM32 and STM8
• Nordic Semiconductor: nRF52832
• Microchip: ATmega8 (AVR)

• Wireless/Radio: Proprietary 2.4GHz (nRF24L01), BLE (nRF52)
• Sensors: BME280 (Bosch), DS18B20 (Dallas/Maxim)
• Interfaces: Register-level control of UART, SPI, I2C, 1-Wire, DMA, and Timers

• Firmware: C (Primary for MCU), C++
• Automation & Scripting: Python (code generation, parsing), Bash / Shell scripting
• Methodology: Pure CMSIS & Register-level development (No heavy HAL abstractions), CPU overhead optimization, and Low Power management

Here are the key repositories that reflect my engineering approach and code quality:

• Overview: A universal, register-level 1-Wire master layer for STM32 with non-blocking DS18B20 temperature and DS2431 EEPROM drivers built on top. The MCU-independent core rides a small port interface; header-only per-family backends cover STM32F0, F1, F3, F4, G0, G4 and H5.
• Key Feature: Every bus slot is generated and captured by TIM1 + DMA hardware automation — zero interrupts, zero busy-waits. Multi-sensor Search ROM, alarm search, per-device addressing, non-blocking command transactions, and a full DS2431 read/write EEPROM cycle, verified on real hardware.
• Stack: C, CMSIS / Register-Level Programming, TIM + DMA, Cortex-M0/M0+/M3/M4/M33.

• Overview: A complete three-link wireless telemetry system spanning three MCU architectures. An STM32F030F4P6 multisensor node (BMP180, Si7021, BH1750) transmits environmental data over nRF24L01+ to an ATmega8 repeater, which controls a load relay and retransmits the datagram across multiple channels. An STM8S003F3 receiver decodes the relayed data and sends it over UART to an OpenWrt-based router, which forwards the telemetry to the internet via a set of scripts.
• Key Feature: Demonstrates cross-architecture interoperability (ARM Cortex-M0, AVR, STM8) with a shared radio protocol, bare-metal drivers, and relay-based automation, with end-to-end telemetry delivery to an internet-connected endpoint.
• Stack: C, STM32F030F4P6, ATmega8, STM8S003F3, nRF24L01+.

• Overview: Firmware for a wireless environmental sensor node measuring pressure, humidity, and temperature.
• Key Feature: Implements direct radio communication on Nordic chips with a strong focus on low-power optimization and standalone efficiency.
• Stack: C, nRF52832, BME280.

• Overview: A shell script for instantaneous scaffolding of a clean, CMSIS-ready project structure for BluePill boards, bypassing bulky IDE project wizards.
• Stack: Bash / Shell.

• Overview: A Python-based CLI tool designed to automatically generate CMSIS-compliant peripheral initialization templates for STM32 MCUs.
• Key Feature: Serving as a lightweight alternative to heavy IDE tools (like STM32CubeMX) for developers who prefer clean, bloat-free bare-metal code.
• Stack: Python, CMSIS, Bare-metal workflow.
