In my first job as a software engineer, I developed Linux drivers myself.
10+ years of experience in the driver layer with C language, which gives me a strong knowledge of control chipsets.
The experience of FAE and MCU has given me strong debugging ability. It makes my project smoother.
3 years of L2+/L3 switch experience let me know the network protocol behavior(VPN,VLAN,STP,IGMP,LLDP,QOS,DHCP).
