• 4.0 GPA. Various awards/scholarships totalling ~$11000
• Former exec and mentor for the UBC CTF team Maple Bacon
• Previously
  • Swift standard library @ Apple
  • Software dev @ Canadian Centre for Cybersecurity

Feel free to contact me about opportunities to work on interesting problems at the intersection of programming languages, security, compilers, or cryptography

• Issue triaging and the bug fixing PR: swiftlang/swift-experimental-string-processing#558 swiftlang/swift-experimental-string-processing#560
• A feature PR: swiftlang/swift-experimental-string-processing#577

• CTF challenge writeups, writeups for some of the CTF challenges I've solved
• Cryptography resources, a work in progress resource for helping beginners get into cryptography

I have many many silly projects

• rlox, A rust bytecode compiler and VM for the Lox language
• tal-inference, type inference on an assembly subset. It kinda works.
• queens, a whole bunch of really really dumb AI players for the Amazons board game, based on this tom7 video https://www.youtube.com/watch?v=DpXy041BIlA
• rust-fractran, did you know that fractions are Turing complete? Watch me compute prime numbers using them
• rop-fk, using return oriented programming to make a bf interpreter

• blake3, a simple implementation of the blake3 hash function in pure java
• py_hash_sigs, while on a flight I implemented some hash based signature schemes, which are very cool (and going to be standardized in the post quantum nist competition! See SPHINCS)
• cryptopals, solutions for the original Matasano Cryptopals sets. Lots of fun attacks on real cryptography

• letter_boxed, a solver for https://www.nytimes.com/puzzles/letter-boxed
• sidewords, a solver for https://sidewords.ca/

• jlox: A java tree walk interpreter for Lox
• minecraft_api, we wanted an api to connect our minecraft server messages to a discord bot, so I wrote this little rust project
• advent, some Advent of Code solutions, a few of these got in the daily top 100 placings!
• sudoku, a little haskell project, just a simple backtracking sudoku solver
• YAOPD, a generator for obfuscated malicious powershell scripts. Originally to be part of a machine learning deobfuscation project but my partner ditched me
• py_spec. You know those circular audio waveform things? I wanted a script that could generate those for me so I wrote one. It works ok
• python-bees, a python implementation of the Artificial Bee Colony algoirthm, which is this weird meta-heuristic algorithm based on bee foraging patterns
