Hands become interfaces. Agents learn to cheat. Models learn to remember. I build these systems—and measure what actually works.
Open to AI / ML internships
Start with the demo. Open a case study for the decisions, experiments, and limits behind it.

Recorded PPO policy · side-by-side with the intended solution
A physics playground where real PPO agents optimise the reward you wrote instead of the task you meant.
Exploit detectors are hand-tuned heuristics: diagnostics, not proofs. Expect false negatives on rewards they were not tuned for.
Real gesture engine · synthetic hand input
A webcam becomes a spatial input device: pinch, drag and throw real Windows windows with your hands.
The demo is the real HUD painter and gesture engine driven by a synthetic hand. A live screen recording is still to be made.
hydra_broadcast — Send the same prompt to every agent in one project.
Interactive architecture · illustrative fleet, real MCP tools
A desktop app that runs Claude Code and OpenAI Codex agents in parallel, with a manager agent that coordinates the others over MCP.
Usage and cost figures are parsed from CLI output: signals, not billing data.
Learned policy · synthetic teacher demonstrations
Demonstrate a pick-and-place with your hand, change the scene, and test what a learned policy actually generalises.
The included checkpoints use synthetic teacher demonstrations, not human webcam data. Human recording is implemented but unvalidated with a participant.
Real pipeline · synthetic desk fixture
Touch a real object in the webcam image, pinch, and lift its appearance out of the video while the background is reconstructed behind it.
Segmentation varies with contrast, clutter, thin, transparent or reflective objects.
Recorded hidden state · memory-intact episode
A PPO laboratory that tests whether agents remember what they can no longer see, by deleting their memory mid-episode.
The strong result concerns retaining a one-time cue in a controlled detour, not learned memory of a door's location.
Working dashboard · synthetic payment events
A real-time dashboard that replays synthetic payment events through an event bus, a risk engine and a guarded conversational analyst.
The public version runs on generated demo data. It demonstrates patterns, not production scale.
DNA design pipeline · simulated expression target
A leakage-controlled surrogate ML pipeline that designs DNA for therapeutic proteins across four plant hosts, and explains its own predictions.
The expression target is a deterministic simulated proxy built from codon, host and structure signals. It is explicitly not wet-lab measured.
I'm an AI engineering student at ESPRIT in Tunis. I like problems where the obvious metric lies.
Agents that game rewards. Gestures that trigger by accident. Models that only work on the layout they trained on. Building the system is half the work; finding out where it fails is the other half.
I work with coding agents as collaborators and review what they produce. That experience led me to build Hydra.
Annual class ranking. AI engineering degree expected in 2028.

Phone video in, metric 3D digital twin out. Today it recovers camera poses with COLMAP, estimates metric scale without a depth sensor (a learned geometry prior plus a bootstrap confidence interval) and fuses a TSDF mesh, on CPU, measured against ground truth. Splats, rooms and floor plans are still planned.

A Flutter field app and a React research dashboard behind one FastAPI gateway serving a wheat-disease CNN, a pest image classifier, an insect-sound classifier and a FAISS-backed retrieval workflow for DNA search.

A PHP/MySQL MVC delivery platform with route views, packaging orders and claims, plus experimental Python sidecars for delivery forecasting and biometric login.

Event booking for Tunisia in Django: QR-code tickets, a Leaflet map of venues by governorate, availability calendars, PDF invoices with VAT and admin analytics.

A C++/Qt operations desktop app on Oracle: inventory and business records with search, stock alerts, charts and PDF reports.

A game written for Linux, played with a gamepad I built on an Arduino board.

I'm looking for AI / ML internships and teams where I can build, test, and keep learning.
