About

I'm a systems programmer who finds rigour in the intersection of mathematics and low-level implementation. Currently in my first year of MEng Discrete Mathematics at the University of Warwick, I write Rust almost exclusively — drawn to memory safety, zero-cost abstractions, and the discipline of working close to hardware. I've built production tools, emulators, games, and async services, always with a preference for correctness over convenience.

Projects

Desktop Japanese Dictionary
A desktop dictionary with a data pipeline ingesting over 1 million entries from JMdict and KANJIDIC. Sub-millisecond lookups via SQLite FTS5, packaged as a native app with a Tauri frontend.
RustTauriSQLite
Code
Gamified Personal Finance Engine
A personal finance tracker with gamification mechanics. Uses fixed-point arithmetic throughout to guarantee monetary precision — no floating-point rounding errors touching money.
Rust
Code
Multi-Threaded CHIP-8 VM
A cycle-accurate CHIP-8 emulator with dedicated threads for CPU, display, and audio. Coordinated via atomic types and lock-free data structures — no mutexes in the hot path.
RustEmulationConcurrency
Code
Bullet Hell Game
A complete bullet-hell game built on Bevy's entity-component-system architecture. Procedural enemy patterns, clean separation between game logic and rendering, and a full gameplay loop.
RustBevyECS
Code
Discord Bot
A Discord bot built on Tokio's async runtime, handling high-concurrency event streams efficiently. Designed to scale without thread-per-connection overhead.
RustTokioAsync
Code
KPI.com Freelance Tool
A Tauri desktop application built during my KPI.com contract. Uses an LLM to parse and categorise bank statement data, with a Rust backend handling document ingestion and structured output extraction.
