About Me
Engineer, Innovator, and Problem Solver.
Hello, I'm Sandun Siwantha.
I am an Associate Electronic Engineer from Sri Lanka, holding a BSc in Physics & Electronics from the University of Kelaniya. I specialize in designing and building complete hardware and software solutions that combine real-time processing, wireless communication, and intelligent automation.
My hands-on experience covers the full product lifecycle. I write robust C/C++ firmware for microcontrollers like the ESP32 and STM32, utilizing frameworks like FreeRTOS and ESP-IDF. On the hardware front, I design and prototype custom PCBs using tools such as Eagle and Altium. To complete the system, I integrate IoT communication protocols like MQTT, Bluetooth, and LoRaWAN, develop PC-side automation tools in Python, and have experience integrating machine learning models like YOLO for smart sensing applications.
If you're working on something exciting and need a technically-driven team player, let's connect.
