Kerberos Based Authentication Implementation

• Implemented Kerberos based authentication for Item Pipeline's Repetitive Task Management System (RTMS), which is a framework used to schedule redrive/republish/reprocessing of entities in the catalog. After my implementation, it is no longer easy for someone to spoof another user when using RTMS.

New Item Pipeline's Repetitive Task Management System Scheduler

• Developed an Amazon Simple Queue Service (SQS) based design for the previous RTMS Job Scheduler with which starvation happened even when other workers were idle due to a modulo on job id.

• Implemented a more scalable and predictable RTMS scheduler with my SQS based design.

• Designed Boot mode including Host Port Interface mode and External Memory Interface mode

• programming the Bootloader and Boot Table.

• Compiled and simulated source code.

• Led a team of six undergraduates in the Line-Tracking Robot Design project.

• Designed the circuit connection among sensors, comparators, PIC, drivers, and motors.

• Achieved First Prize in the final race (rank 1/20 groups).

• Participated in system-building program and the host system construction program in Changsha South Railway Station.

• Data collection for the construction of intelligent traffic variable message signs.
