I am currently an undergraduate studying computer science and applied mathematics at the National University of Singapore (NUS). This is a double degree programme, which will allow me to graduate with a Bachelor of Computing (BComp) in Computer Science, as well as a Bachelor of Science (BSc) in Applied Mathematics. I am a recipient of the NUS Merit Scholarship. I should graduate in 2021.

I have participated in many algorithmic programming competitions, such as the ACM-ICPC World Finals, the International Olympiad in Informatics (IOI), and the Google Code Jam. When opportunities arise, I continue to participate in such competitions.

I also tinker with technologies and write some code during my free time. See below for some of my personal projects.

Interests:

• Algorithmic problem solving
• High-performance software development
• Lock-free and wait-free parallel programming
• C++ programming language
• (and there might be more …)

Work Experience:

• Software Engineer Intern (Core Development) at Jump Trading
  June – August 2019
  This internship comprised a four-week training programme at the Chicago headquarters, and then six weeks of work at the Singapore office. I worked on the portion of the trading platform that receives market data, which is used by trading teams to efficiently receive and parse data from exchanges. My work improved the compilation time and execution performance of the trading platform.
  Technologies: C++14/17

Personal Software Projects:

• Circuit Sandbox
  May – August 2018
  GitHub repository | Poster |
  Circuit Sandbox is a digital sandbox game where users can create arbitrarily complex circuits out of simple components. To support large and complex simulations efficiently, Circuit Sandbox uses many careful optimisation techniques, such as lock-free multi-threading and C++ template metaprogramming. Circuit Sandbox is a collaboration with Kuan Wei Heng, for our Independent Software Development Project (Orbital) module at NUS.
  Technologies: C++17, Boost, SDL2
• Jelly Compiler for Brainfuck / wasm-codegen
  March 2017
  Try it here! | GitHub repository |
  Jelly is a browser-based compiler for Brainfuck, one of the most well-known esoteric programming languages. Jelly features an optimising compiler (written in JavaScript) that compiles Brainfuck to WebAssembly, which can then be compiled to native code and executed in the browser. This allows much faster execution as compared to other browser-based compilers.
  Technologies: JavaScript, WebAssembly

Other Experience:

• National Olympiad in Informatics (NOI) Scientific Committee
  January – March 2017
  January – March 2018
  January – July 2020
  The National Olympiad in Informatics is an algorithmic problem solving competition for secondary school and junior college students in Singapore, modelled after the International Olympiad in Informatics. The scientific committee prepares and ensures quality control the tasks in the competition. In 2017, I reviewed and tested the competition tasks. In 2018, I designed and prepared some tasks which were eventually used in the competition. In 2020, I was in charge of the scientific committee, and led the team in task selection and preparation, to ensure the quality and fairness of the competition tasks.
