DARSHAN JIVRAJANI

My responsibilities included developing firmware for automation hardware, with a focus on microcontrollers, and sensors. I worked with various platforms such as ESP32, Texas Instruments (CC1312, CC1352, CC3235SF) microcontrollers.

Key projects involved:

• I2S interfaces.
• Sub-1 GHz communication.
• RGB drivers.
• Drone applications.

I led significant initiatives, including the development of a 5G-based Fixed Wireless Access system, and mmWave communication projects. These roles required optimising firmware and integrating advanced communication and security features, showcasing my expertise in embedded systems, and innovation.

My responsibilities included developing firmware based on client hardware requirements, using Embedded C/C++ and Python. I managed development roadmaps to prioritise tasks efficiently.

My projects involved:

• Data loggers.
• Smart switches.
• Smart Parking systems with indoor navigation.
• Smart Helmets for construction sites.
• Pixel LEDs.
• Induction-based systems.
• ECG devices.

I leveraged platforms like ESP32/8266 and Nordic semiconductors for BLE (4.0/5.0/5.2), and worked with various interfaces, including UART, SPI, I2C, I2S, WiFi, BLE, ZigBee, LoRa, sub-1 GHz, 4G/LTE and NB-IoT. Collaboration with cross-functional teams ensured the successful delivery of integrated, embedded solutions.

I worked at a start-up company specialising in IoT, contributing to several innovative projects.

• Mini Computer: Developed a device similar to a mobile phone, featuring a processor (CPU), a Pico projector for the monitor, and a laser-based keyboard.
• Smart Switch: Designed and implemented IoT-based smart switch systems, providing automation solutions.
• Employee Work Status System: Created an employee tracking system to monitor work status and productivity, enhancing workplace management.

These projects allowed me to engage in cutting-edge hardware integration, optimize functionality, and deliver effective IoT solutions in a startup environment.

During my tenure at Nkkonnect Infoway, I worked on various key projects.

• Smart Switches: Developed firmware, designed PCBs, and contributed to hardware installation for smart touch switchboards, replacing traditional mechanical switchboards.
• Solar Panel Control: Worked on automation and control systems for optimising solar panel performance.
• Tile Automation: Contributed to automating tiles for various applications.

In these projects, I honed my skills in Embedded C, C/C++, Python, PCB design, circuit analysis, and debugging.
