- **[Weenix](/essays/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. - **[Weenix](/essays/weenix/)**\
- **[Networking Stack from Scratch](/essays/networking-stack/)** — 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. Unix-like kernel in ~7,000 lines of C.

- **[Where Does SIMD Help Post-Quantum Cryptography?](/essays/where-does-simd-help-post-quantum-cryptography/)** — 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.
