Louai Ben Hassine

[ About ]

I'm in my second year of computer engineering (génie informatique) at Université Laval. Outside class I build things end to end: a graph engine in C++, a movie recommender that runs on a local model, a terminal helper, and a calorie tracker that never leaves the browser.

I care about what a model is allowed to see, what it's allowed to claim, and how you prove it works: benchmarks, tests, and answers that show their sources. I like software that is fast, runs on your own machine, and does one job well.

[ Selected work ]

Built end to end, measured, and open source.

01C++20 · Python · 2026

Chronos-Graph

A code-graph engine that hands AI agents the right code.

Indexes Python and C++ into one call graph, across the pybind11 boundary.
Ranks code by embeddings and PageRank, then prunes it to fit a token budget.
PageRank runs 161× faster than NetworkX; a sandboxed agent can fix a failing test.

02Python · RAG · 2026

LBH Cima

A movie recommender that isn't allowed to make things up.

Embeds each request and matches it against 4,800 films by cosine similarity.
A local Llama 3.2 answers through Ollama, restricted to the films retrieval returned.
A citations panel shows the similarity scores a RAG app usually hides.

03zsh · Swift · 2026

Zap

Plain words in, shell command out.

Type /zap and what you want in Terminal; it writes the command and asks before running.
Commands that delete or overwrite get a red warning and need an explicit yes.
Answers in about half a second on Groq, or through Claude or a local model.

04JavaScript · PWA · 2026

Kalo

A calorie tracker that never leaves the browser.

No dependencies, no build step and no backend: everything lives on the device.
A photographed plate is matched against a local food table in about 5–10 ms.
“2 eggs and a black coffee” parses into logged items; installs as a PWA.

Quoridor engine

Full rule validation in Python, including the path-existence check that stops a wall from sealing a player in. CLI, REST client and unit tests.

Hide or Die

A hide-and-seek game on Roblox, in public beta: maps, a custom dark interface and phone controls, written in Luau.
Editor tooling

Unreal Engine 5 editor plugins and scripted After Effects panels, written to delete manual steps from my own workflow.
