Profile#

Third-year computer science student and developer with more than ten years of programming experience. I build and operate software used by hundreds of thousands of people: a sharded Discord bot with 200,000+ users, a JavaScript library with 120,000+ downloads, and developer tools in C++, Rust and Python. Strongest in C++, Python and JavaScript, comfortable anywhere from Linux internals to the web.

Experience#

Relaxy! · creator and sole developer#

2021 – present · relaxy.xyz

• Designed, built and operate a multipurpose Discord bot serving 200,000+ users across 280+ servers.
• Sharded architecture (a manager and N cluster processes) on Node.js and MongoDB, with 162 public commands and 58 event handlers.
• One moderation pipeline shared by commands, the dashboard and cross-server sync; OCR and perceptual-hash scam detection.
• Built the Fastify dashboard (Discord OAuth, three permission tiers, CSRF protection, allow-listed writes), the website and the public status page.
• Run the whole ecosystem on a single Raspberry Pi: Podman and bubblewrap isolation, health probes for 24 services, a hardware watchdog and incident tooling.

Fancy Games · community manager, Escape the Backrooms#

Ongoing

• Help run the official community for Escape the Backrooms.
• Own the Escape the Backrooms Community organisation: a speedrun verification bot (Python, talking to Discord's gateway directly), the LiveSplit autosplitter, a UE4SS fork and the community wiki.

Student research group · founder#

University

• Founded and run a student research group focused on machine learning.
• Take part in hackathons, WDI events and CTFs.

Selected open source#

• emoji-mixer (JavaScript): 120,000+ npm downloads, 1,221 dependent repositories; shrank a 96 MB dataset to 2.4 MB.
• LogEye (Python): runtime introspection logger built on sys.settrace, 10,000+ PyPI downloads.
• Lexiglance (C++26, Qt 6): system-wide pop-up dictionary reading text through accessibility APIs or OCR, with offline translation.
• simple-project-tracker (Python): CLI with frecency lookups, undo and a background daemon; about 10,500 lines and 17 test modules.
• hprint (C++23): header-only library for centred terminal headers.

Education#

Computer science, undergraduate#

2024 – present

• Projects beyond the brief: a multithreaded neural network from scratch (C++26), a multi-process hospital simulation using only POSIX IPC (C++20), a sorting visualiser and benchmark suite (OpenGL, SDL3), finite-difference solvers for PDEs.
