Our IoT & Embedded Systems Services
Firmware Development
We develop robust, optimized firmware for microcontrollers and microprocessors across ARM Cortex, AVR, PIC, ESP32, and STM32 platforms. Our firmware engineers write efficient C/C++ code for bare-metal and RTOS environments, ensuring low-latency performance, minimal power consumption, and reliable operation in safety-critical and commercial-grade embedded applications.
Device Driver Engineering
Our engineers build custom device drivers for Linux, Windows, and RTOS-based systems that enable seamless hardware-software communication. From USB, SPI, I2C, and UART interfaces to complex peripheral controllers, we deliver production-ready kernel-level and user-space drivers that integrate tightly with your hardware platform and operating system stack.
Sensor Integration & Calibration
We integrate and calibrate a wide range of industrial and commercial sensors, including temperature, pressure, humidity, accelerometers, gyroscopes, LiDAR, and GPS modules. Our team ensures accurate data acquisition through signal conditioning, filtering, and calibration algorithms that deliver reliable real-time measurements for your IoT ecosystem.
IoT Cloud & Edge Computing
We architect and deploy scalable device-to-cloud solutions using AWS IoT Core, Azure IoT Hub, and Google Cloud IoT. Our edge computing implementations process data locally on gateways and edge devices, reducing latency and bandwidth costs while enabling real-time analytics, OTA firmware updates, and centralized fleet management dashboards.
Industrial IoT (IIoT) Solutions
We design and deploy Industrial IoT platforms for manufacturing, energy, and logistics operations. Our IIoT solutions encompass predictive maintenance systems, SCADA integration, Modbus and OPC-UA protocol support, and real-time asset tracking that help enterprises reduce downtime, optimize throughput, and achieve measurable operational efficiency gains.
Embedded Linux & RTOS
We build custom Embedded Linux distributions using Yocto and Buildroot, and develop applications on real-time operating systems such as FreeRTOS, Zephyr, and VxWorks. Our expertise covers BSP development, kernel customization, bootloader configuration, and system optimization to deliver deterministic, production-grade embedded platforms.
