Experience

1. Firmware Engineer

   Broadcom

   Jul 2014 — Present

   Support customer issues reported from Apple, Samsung, Huawei, LG, etc. and resolve firmware issues reported from SVT (Software Verification Test) team on combo chip.(43342A2, 4358A3, 4345C0)- Capture Host-to-Controller log and OTA (over the air) trace by GPIO toggling, sniffer, and Bluetool and analyze the log and timing- Use ARM JTag debugger / GPIO Toggling / Debug Framework to debug firmware and crash issues- Porting Bluetooth firmware features to chipsets after taping out the chip.• Manage the firmware team’s test lab to help team trouble shoot issues found in the nightly regression test- Setup test bench and run sanity test- When there is a sudden break, quickly reproduce the problem and get trace for team member to fix.
