Rakesh V

Embedded Firmware Engineer with 2+ years of hands-on experience developing production-grade firmware for industrial IoT, Building Automation, Battery Management Systems (BMS), and Power Management. Proven track record in end-to-end firmware development on ARM Cortex-M (STM32, ESP32) using FreeRTOS and bare-metal architectures. Deep expertise in industrial communication protocols (Modbus RTU/TCP, BLE Mesh, LoRa, MQTT), embedded HMI development using LVGL, and hardware bring-up with oscilloscope and logic analyser debugging.

Domain knowledge closely aligned with energy automation, smart grid, and power systems.

Embedded Firmware Engineer at Qmax Systems Pvt. Ltd. (2024-09 – Present)

• 3-tier BMS architecture: Firmware owner across a Linux master controller → 7 hub nodes → 700 ARM Cortex-M3 (ADuCM355) cell sensors, collectively monitoring 1,400+ batteries in a single live system via Modbus RTU/TCP.
• IoT Building Management: Delivered BLE Mesh firmware across 20+ nodes for smart lighting, energy monitoring (EMR), air quality, ammonia sensing, and LVGL-based 4-inch / 7-inch HMI with AC and lighting control, human presence automation.
• Power Management HMI: Built LVGL 7-inch TFT dashboard monitoring 7 independent power units — solar, generator, battery, PoE — with real-time production vs consumption display over Modbus RTU.
• Wrote DMA-accelerated, interrupt-driven peripheral drivers with FreeRTOS task scheduling, watchdog, and low-power sleep modes; hardware bring-up across 4+ concurrent projects using oscilloscope and logic analyser.

Embedded Firmware Intern at Qmax Systems Pvt. Ltd. (2024-01 – 2024-08)

• Developed and validated Embedded C peripheral drivers (UART, SPI, I2C, ADC, GPIO, Timers); contributed to BLE Mesh lighting firmware and LVGL UI screens with relay and sensor integration.
