Top SchoolWen-chen Lo is a software engineer with 11 years of experience specializing in backend and distributed systems, currently working on Siri Platform Infrastructure at Apple. He brings deep systems and networking expertise—C/C++ and Java at scale—having built P2P libraries, RTSP streaming servers, and storage managers that improved throughput, latency, and bandwidth efficiency in prior roles. Comfortable across cloud and big-data stacks (Hadoop, Spark, AWS) and databases from MySQL to Cassandra, he blends low-level performance tuning with API and service design. A strong foundation in electrical and communication engineering (NTU) plus CS masters work at UIUC underpins his pragmatic approach to complex concurrency and networking problems. Notably, his past work reduced server traffic by ~20% and maintained 99.9% availability for 100k concurrent sessions, reflecting a focus on measurable operational impact.
