I design embedded systems and PCBs for clients building hardware products. My work spans the full stack of a hardware product — schematic capture, PCB layout, firmware, IoT cloud integration, and the mobile app that talks to the device. Most embedded engineers stop at firmware. I go all the way to the app your customer holds in their hand.

Before going independent, I spent five years at Synopsys as a senior engineer verifying RTL, CDC, and RDC for large SoCs — including designs for Intel and other tier-1 semiconductor companies. That work gave me a deep understanding of how silicon behaves, which informs how I think about the hardware I build today.

My hands-on experience spans EV thermal management systems with CAN-bus control loops, medical device R&D using IVF protocols, industrial IoT sensor nodes, and consumer electronics prototypes. I've worked across ESP32, ARM Cortex-M4, ATMEGA, C2000, and STM32 platforms, and I'm comfortable with FreeRTOS, CAN, LoRa, MQTT, and Modbus.

I'm currently a visiting lecturer in Digital Systems Design at South Eastern University of Sri Lanka. I take on freelance hardware projects remotely — my timezone (+5:30) works well for UK and EU clients, and I'm comfortable with async collaboration across timezones.
