Aditya Raj C.

I am an Embedded Software Engineer with 5+ years of experience, specializing in firmware development, BLE security, IoT solutions, and medical device compliance. I have worked on projects ranging from secure medical devices (insulin pump, heart monitoring systems) to IoT-based smart home and industrial solutions using STM32, ESP32, Nordic nRF52, and Beken controllers. 💡 Key Expertise: Firmware & Drivers: Embedded C/C++, FreeRTOS, device drivers (SPI, I2C, UART, USB, SD card, sensors). Wireless & IoT: BLE (HARA/TARA, AES-CCM, FIDO2), Wi-Fi (ESP-IDF, ESP32), Alexa integration, Firebase, ThingsBoard, OpenRemote. Medical Standards: IEC 62304, ISO/IEC 60601-1-8 (medical alarms), secure communication for medical devices. Low-Power Design: Optimized devices to run on 2–4µA for wearables and portable devices. Cloud & OTA: IoT cloud dashboards, wireless OTA updates, data logging, and real-time monitoring. ✅ Highlighted Projects: Insulin Pump Firmware (IISc): Basal/bolus control, BLE security, alarms per IEC standards. Biometric Access Card (Cionlabs): Multi-fingerprint enrollment, BLE authentication, FIDO2 integration. IoT Smart Devices: Smart LED bulbs, ESP32 camera, Alexa-enabled devices, dairy IoT monitoring systems. Home & Industrial Automation: Wi-Fi + BLE integrated devices with secure OTA and cloud connectivity. I bring a blend of deep technical expertise, compliance knowledge, and hands-on development skills to deliver reliable, scalable, and secure embedded solutions. 🚀 If you’re looking for a developer who can take your IoT, embedded, or medical device project from concept to working product with precision and quality — let’s connect!
