Project details
If you're building a hardware product or working with low-level systems, you need someone who understands both hardware constraints and software performance. I help startups and enterprises design and ship reliable, production-grade embedded systems from firmware development to full IoT integration.
Whether you're working on a prototype, MVP, or scaling an existing product, I bring a structured engineering approach to ensure stability, efficiency, and scalability.
What I Can Help You With
• Firmware Development: Bare-metal & RTOS-based firmware (FreeRTOS, Zephyr), C/C++ embedded programming, peripheral drivers (UART, SPI, I2C, CAN, GPIO, ADC, PWM), real-time systems.
• Microcontrollers & Platforms: ARM Cortex (STM32, NXP, Nordic nRF), ESP32/ESP8266, Arduino, Raspberry Pi.
• IoT & Connectivity: MQTT, HTTP/HTTPS, WebSockets, WiFi, BLE, LoRa, Zigbee, Cloud integration, OTA firmware updates.
• Hardware Integration: Sensor & actuator integration, motor control, power optimization.
• Debugging & Optimization: Firmware debugging, memory optimization, performance tuning.
• Linux Embedded Systems: Embedded Linux development, device drivers, Bash/Python scripting.
