Projects

Index of engineering artifacts. Systems depth is the primary axis of this page; machine-learning and deployed artifacts follow.

Low-Level & Systems

• Weenix
  Unix-like kernel in ~7,000 lines of C. Virtual memory, VFS, system calls, threading, device drivers, interrupt handlers, and file systems; custom linker support for running userspace x86-64 ELF binaries. Originally a project from Brown CS 169 (Operating Systems with Lab), extended with further features like pipes and userspace preemption. January – May 2025.
• Networking Stack from Scratch
  TCP/IP, RIP, UDP, and DNS in Go, supporting file transmission of up to 1 GB across networks of 8 virtual machines. Extended with a fully RFC-compliant SSH implementation (2,000+ additional lines) supporting sustained sessions of arbitrary length. October 2024 – July 2025.
• Where Does SIMD Help Post-Quantum Cryptography? · Artifact
  Hand-written AVX2 assembly for ML-KEM / Kyber. 35×–56× speedup over compiler-optimized C for core NTT arithmetic; 5.4×–7.1× end-to-end KEM speedup. Full statistical-analysis pipeline (Mann-Whitney U, Cliff’s δ, bootstrapped CIs) on Brown’s OSCAR HPC cluster. Phase 1 report and reproducible artifact public; Phase 2 (PAPI, RAPL) and Phase 3 (ARM NEON/SVE, RISC-V V) in progress.

Machine Learning & Deployed

• ICD-10-CM outcome calculator · Preprint · Code
  Public, read-only calculator for the permutation-invariant Deep Sets model underlying the paper currently under review at JAMA Network Open. Takes a diagnosis-code set; returns 30-day readmission and postdischarge mortality predictions with Integrated-Gradients attribution.
• NeuroPose
  3D pose-estimation and kinematic-analysis system for neurological-recovery research in Liqi Shu’s laboratory at Brown Neurology. Python/TensorFlow inference pipeline, MATLAB-based statistical post-processing, Rust backend with HTML/JS frontends. 20,000+ lines across four externally-funded sub-projects since 2023.
