Engineering & CS

A Rustlings-style CLI that teaches operating systems by making you build a RISC-V kernel, one exercise at a time. The test suite boots your kernel in QEMU and reads the serial console, so a green test means it actually ran.

Adopted for the operating systems course I assist

Does seeing a concept beat reading about it? A survey of 55 students, interviews with three professors, and the literature behind both. Visuals led on understanding, text held on for precision, and the design that survived was neither: teach the same step both ways and let the learner switch.

Course research, ongoing

A desktop screenwriting app whose AI collaborator reads your actual script. It pulls in earlier scenes on its own and proposes edits as diffs you accept or reject, so it never overwrites your words behind your back.

A gamified Android focus timer shaped as a boss fight. Every focused minute damages the villain; opening something you were avoiding raises a full-screen overlay that walls it off until you come back. The 846 tests grew around two bugs that reached real testers, a reward exploit and a migration that locked outfits players had already earned.

Where inside a language model does “this is a math question” get decided, and does that decision drive what it says next? 300 real prompts, 24,576 sparse features, then activation patching to separate what is causal from what merely correlates.

Built with two others

One hotel review and booking application, rebuilt five times across a semester. It starts as a JSON parser and ends as a servlet app on MySQL with sessions, bookings and an agent that answers questions about the reviews. The fourth build was HTTP written on a raw socket, before a framework was allowed.

Coursework, private repository

A browser extension that rewrites your prompt inside ChatGPT's own input bar, one click, without leaving the page. Spring Boot behind it, with LangChain4j handling the model calls.

Built with one other

A Blender addon that takes plain English and edits the 3D scene. Type “move cube to 1,2,3” or “apply red material to sphere” and it does.

Friends lock up money against an event and earn on-chain reputation for turning up. Built on XRP over a hackathon weekend.
