Nola-Yang/README.md

Hi, I'm Nola 👋

Systems & low-level software developer. I like building things from the metal up — operating systems, language runtimes, concurrent data structures, and firmware — in C, C++, and ARM assembly, and sometimes all the way down to the gates in HDL.

  • 🛠️ Close to the metal: C · C++20 · AArch64/ARMv8 assembly · POSIX · VHDL/Verilog
  • 🧠 Into operating systems, computer architecture, concurrency, and embedded systems
  • 🪶 On the side: computational approaches to classical Chinese poetry — prosody parsing & authorship stylometry
  • 🌱 Open to systems / embedded software internships and new-grad roles
  • 📫 Reach me at moyuean2020@gmail.com

📜 Computational humanities — classical Chinese poetry

Where my systems/compiler side meets a long-standing interest in classical Chinese literature. A poem in a fixed form is a formal grammar; "who wrote this?" is a classification problem.

Project What it is Stack
classical-chinese-nlp A prosody linter / type-checker for 诗 · 词 — parses each character's historical tone (平/仄, including the 入声 that modern Mandarin lost) and validates against 近体诗 templates & 《钦定词谱》 with compiler-style diagnostics — plus a from-scratch stylometry / authorship-attribution engine (Burrows's Delta, char-bigram LM, leave-one-out), with two real authorship case studies: 岳飞《满江红》 and the Qing poet 贺双卿. C++ · Python
