PROJECTS

1. Nintendo Entertainment System (NES) Emulator

   Feb. 2025 – Mar. 2026

   Concurrency, Low-Level Systems, Hardware Emulation, C++

   • Implemented core NES components (6502 CPU, memory map, bus) around a shared clock architecture.
   • Parallelised the entire system with separate threads per component operating at single-tick granularity.
   • Built and debugged a high-concurrency design with an emphasis on determinism and system stability.
   • Analysed performance trade-offs of cycle-accurate emulation: context-switch overhead vs synchronisation costs.
   • Strengthened low-level debugging skills: timing issues, race-prone logic, and system testing strategy.

2. Advanced Encryption Standard in Parallel (AESP)

   Jan. 2026 – Feb. 2026

   Parallelism, Applied Cryptography, API Design, Library Development, Rust

   • Developed and published a pure-software AES library in Rust, prioritising performance on multi-core CPUs.
   • Benchmarked against serial implementations and achieved near-linear speedup across cores on larger inputs.
   • Implemented multiple AES modes (ECB, CTR, GCM) and validated using NIST known-answer test vectors.
   • Authored clear crate documentation and a thorough unit test suite to catch regressions early.
   • Built a CLI for file encryption/decryption with practical flags, strict input validation, and structured error handling using idiomatic Rust patterns.

3. EchoPulse — Tech eChallenge

   Mar. 2025 – Jul. 2025

   UX Design, Market Research, Marketing, Teamwork, Public Speaking

   • Designed a mobile app concept to guide users through life-saving first aid when emergency services are unreachable, working in a team of four.
   • Conducted interviews with industry professionals (medical, legal, and technical) to validate constraints and iterate on the product direction.
   • Pitched the concept to a judging panel and progressed to the final round (top 10 of 60+ teams).
