I’m also known as Chi Zhang, where Zhang is my last name. As the name is too common in Chinese culture (there are at least four students of this name in my school), I would be happy if you could call me Alex Chi (or 迟策).
I’m a sophomore undergraduate student majoring in Computer Science at Shanghai Jiao Tong University.
Expected to graduate in 2022.
Currently I have research interest in computer systems. I made a RISC-V simulator after reading CS:APP and CA:AQA. I adapted Tomasulo algorithm and Speculation of a single float unit to a fully-functional RISC-V simulator.
💻 RISC-V Simulator of RV32I ISA. Out-of-order execution with Tomasulo algorithm and Speculation. Now with detailed runtime information and a full report on this project.View on GitHub
I’ve implemented a variety of interesting things in distributed systems, computer graphics, programming language, and machine learning.
⛵ Raft Consensus Algorithm. gRPC for communication. Tested with a few cases.View on GitHub
⚡ A ray tracer implemented in Rust based on "Ray Tracing in One Weekend" featuring multi-threaded rendering and a variety of preset scenes.What did it render?
💎 A Lisp interpreter in RubyView on GitHub
🔢 MNIST training of minimal dependency implemented in Rust. Trained with fully-connected layers.View on GitHub
Recently I took part in SJTU CTF 2019, a kind of information security competition. There’s no general procedure for solving these problems. To tackle these interesting challenges, I applied some tools already known to me and then solved them with my own innovative ideas.

I’m also capable of using web-based tools to visualize data and create user-friendly UI.
🌈 BlueSense is a low-cost IoT platform for collecting and visualizing environment data. It has been collecting climate data in Shanghai for over 2 years.

In some team projects, I collaborated with other members on mechanical design, programming and oral reports. I created programs on embedded platforms.
🎾 A robot automatically finds and fetches tennis balls on the ground. Use OpenCV on Android for computer vision. Final project for SJTU ME116 "IntroME".How does it work?
