Kevin Hsin-Kai Wang has experience building distributed computing environments using Apache Spark and migrating models between R, Scala, and Python. He has interned at HBI Solutions since 2015 developing Spark clusters and at MediaTek in 2014 building a network simulation in OMNeT++. Wang received his Master's in Electrical and Computer Engineering from UC San Diego in 2015 and Bachelor's in Electrical Engineering from National Taiwan University in 2012. His projects include implementing sliding window protocols, routers, a Tetris game, MapReduce jobs, and a gesture-based data transfer app.

Project Experiences
Network Projects in C Language
• Implemented a Sliding Window Protocol to transmit messages between multiple senders and receivers, to ensure reliable,
in-order delivery across unreliable links through CRC (cyclic redundancy check), message partition in senders, acknowledgments,
sequencing numbers and SWP implementation.
• Architected a router to forward frames between hosts and communicate between internet and Ethernet layers. Used ARP
(Address Resolution Protocol) cache implementation and six kinds of ICMP (Internet Control Message Protocol) handling,
checksum and longest prefix IP to match with routing table in the actual RFC specification.
Tetris Game Project in Java
• Individually built a Tetris game from scratch with a Java Swing object user interface.
Network Service Projects in Java, C, and Python
• Developed a server in C which accepted HTML requests and returned secure and concurrent responses. The server can accept
new connections, receive well-formed HTTP/1.0 requests, and determine if a target file exists and permissions are set properly.
• Implemented a series of MapReduce jobs that calculate various metrics over the Netflix dataset with Hadoop.
• Used Python’s client program and Java server to recreate a Twitter service through Thrift toolkit.
Operating System Projects using the Java version of the Nachos Instructional Operating System
• Built a thread system with a lock condition variable and sleep/ wake functions.
• Created functions to encapsulate the state of a user process that is not contained in its user thread- including address translation
state, a file table, and information about the program being executed.
Developed a System-Performance Measuring Tool using low-level C system calls in Windows
• Developed a system-performance benchmark to measure CPU time, scheduling, OS Services, and file system with Microsoft
Foundation Classes in Windows 8.
Computer Architecture Project in C++
• Implemented the prefetcher interface with self-designed algorithm (a combination of Markov chain and sequential prefetching)
to implement the prefetching in 32KB, 16 byte line size, 2-way set associative data cache and 256KB, 32 byte line size, 8-way set
associative L2 cache.
Won Third Place in Adder and Multiplier Design Competition using Verilog and Python
• Use Python to generate 10,000 lines of Verilog code to complete the 64*64 multiplication in Wallace Tree structure; ranked
third place.
Android Phone Projects in Java
• In a Gesture-based data transfer application, created a way to trigger data transmission with hand gestures through sensors and
Bluetooth. In a Near-Field Communication (NFC) application, constructed a light control panel and set up the NFC-triggered
module when NFC was the state-of-the-art technology on android phone.
