Portrait of Lounis Hamroun

Lounis Hamroun

AI / ML Engineer

I build and study modern AI systems, with interests in model internals, inference, evaluation, and reliable ML engineering.

Paris, FranceSeeking a 6-month internship from January 2027

About

I am currently completing a Specialized Master's in Artificial Intelligence at Télécom Paris, after an engineering degree in Computer Science from IMT Nord Europe. I am interested in understanding modern AI systems beyond high-level APIs, from model architecture to inference and deployment.

Recently, I rebuilt GPT-2 from first principles in PyTorch and studied GPU execution through Triton kernel implementation and benchmarking. Previously, I worked on LLM infrastructure and MLOps at Air Liquide.

I am currently looking for a six-month AI/ML engineering or research engineering internship starting January 2027.

Selected Work

PyTorch · Transformers · Model Internals

Rebuilding GPT-2 From First Principles

Reimplemented GPT-2 inference from scratch in PyTorch, including causal self-attention, transformer blocks, weight loading, and autoregressive generation, while validating intermediate representations against a reference implementation.

Triton and PyTorch softmax performance benchmark

Triton · PyTorch · GPU Benchmarking

Triton Softmax & GPU Performance

Implemented and benchmarked a fused row-wise softmax kernel on an RTX 5090, investigating shape-dependent performance and a sharp regime change around the 8192-element block-size boundary.

Industrial visual anomaly detection results

PyTorch · Computer Vision · PatchCore

Industrial Visual Anomaly Detection

Built an unsupervised visual anomaly-detection pipeline for industrial automotive inspection using frozen ResNet features, patch representations, memory-bank retrieval, and nearest-neighbor anomaly scoring.
