Hello, I'm Zhilei Zheng

I am sophomore undergraduate student studying Networked and Social Systems Engineering at University of Pennsylvania.

My interest is in building scalable software products and services with optimized user experience. Fluent in Java, JavaScript, Ruby, Swift and Python, I have accumulated experiences and a number of production-level projects in Web Development, iOS and Android Development.

Academic-wise, I concentrate on cloud computing infrastructure, platforms and services. My recent study directions also include blockchain protocols.

I am currently an iOS developer at Pennlabs, Director of Technology at Penn Wharton China Summit, and a Teaching Assistant for Ruby on Rails Course (CIS-196).
