Message

At HCL Technologies, I managed the CADD Solis Infusion Pump development program and contributed to firmware updates from prototype through beta, DVT, and PVT. I led integration of device drivers, FreeRTOS configuration, and a port of the legacy application, and improved battery life by reworking sleep-stage logic.

At Mettler Toledo Turing Softwares, I led development and quality control for European retail weighing scale firmware and software. I ported the source code base to the IAR compiler, extended RAM availability, and developed a new UI using uC-GUI.

At Samsung Research Institute, I contributed to the development and commercialization of Android smartphones, including Galaxy S2, S3, and S4. I developed an Android Linux Kernel and boot-loader debug module to extract core dumps and processor status registers, and worked on ARM-based smartphone board bring-up.
