Lalith K.

Are you building an IoT product and need firmware that actually works in the field? I'm Lalith, an Embedded Firmware Engineer with 3+ years of hands-on experience delivering production-grade firmware for IoT devices. I specialize in: Microcontrollers: STM32, ESP32, ESP32-S2/S3, nRF5340, Raspberry Pi Protocols: SPI, I2C, UART, BLE, MQTT, HTTP/HTTPS, USB, Ethernet RTOS & Bare-Metal: FreeRTOS, Zephyr RTOS, DMA, OTA, Secure Boot Tools: ESP-IDF, STM32CubeIDE, PlatformIO, Balena OS I've worked across the full product lifecycle — from driver development and sensor integration to test firmware, production support, and OTA updates. My work at Alomind Labs and Adapt Ideations gave me deep experience building reliable IoT data loggers, and I currently deliver embedded products as a contractor at Spastha Dynamics. On Upwork, I've built a strong track record with clients across the globe, consistently delivering quality firmware on time. If you need someone who understands both the hardware and the software side of embedded systems, let's talk.
