About Me
- Worked in Japan (2014–2022); relocated to the United States in 2024
- Master's student in Computer Science at San Francisco State University (Expected graduation: Dec 2025)
- Passionate about systems programming and low-level software development
- Currently exploring high-performance computing, compilers, LLVM backend and AI chip emulation.
🧑💼 Professional Work
- Founded mikan and developed Japan’s most popular (9M+ downloads) English vocabulary app from scratch.
- Maintained BitcoinKit (800+ stars), with 345+ contributions across features and fixes.
🎓 Academic Projects
- High-Performance Computing (CSC746) - 99% (A)
- Used C++, CUDA, MPI, and OpenMP
- Designed shared-memory parallel programs for multi-core CPU and GPU systems and analyzed performance using runtime, speedup, memory bandwidth, and cache metrics.
- Conducted various experiments on Perlmutter at NERSC (HPE Cray Shasta platform)
🧪 Hobby / Independent Projects
- Built a Bash clone in C and wrote a detailed guide on incremental, unit-test-driven shell development.
- Developed Quines, self-replicating programs that output their own source code.
- Created an ELF executable packer that encrypts and compresses ELF binaries, which automatically decrypts itself at runtime.
- Reimplemented the nm command to analyze ELF binaries and extract symbol table information.
- Built a Turing Machine Emulator to learn OCaml and understand Turing Machine operations.
- Currently reimplementing the POSIX lex command as a preparation for future compiler development.
