About

I’m Sy.

My background is in developer tooling; I’ve worked on compilers, debuggers, profilers, language runtimes, standard libraries, IDEs, everything.

I currently work as Microsoft’s C++ Developer Advocate.

Some notable projects of mine:

I wrote the largest resource on debugger implementation, Building a Debugger, which walks you through writing an entire native x64 debugger from scratch
My implementations of std::expected and std::optional
My C++ ranges library
I have designed and implemented several esoteric programming languages:
- li1I: A language where the only valid characters are l, i, 1, I, and whitespace
- Enjamb: A poetic language where it’s not what’s in your lines that matters—it’s where you break them
- vizh: A visual programming language whose input files are images, ideally created in MS Paint
- dwarbf: A Brainfuck interpreter embedded in DWARF debug information
- elmscrew: An online visual Brainfuck debugger
I wrote the recommendation engine for the arkham.build deckbuilder for Arkham Horror: The Card Game
I’ve contributed to several C++ features:
- Deducing this (P0847)
- std::views::cartesian_product (P2374)
- Monadic operations for std::optional (P0798)
