Tech Recruiter
In one sentence : what's your profile?
Idir Meradji
A software engineer focused on AI/ML who builds from the ground up as comfortable with knowledge graphs and SPARQL as with computer vision and deep learning.
I like the whole path, from the maths of a model to the final product.

What sets you apart from other AI profiles?
Idir Meradji
I learn things by rebuilding them, a Transformer tensor by tensor, an OWL ontology by hand, classical vision wired into a CNN. I want to understand the machinery before I use it.
And I care as much about clean pipelines and honest evaluation as about the last point of accuracy. A model that only works in a notebook isn't done.

What are you most into right now?
Idir Meradji
Honestly, most of what moves fast. I'll spend a weekend on a generative architecture as happily as on a data pipeline or an optimization problem.
That range is what pulled me into AI in the first place and it's what keeps me here.

experience

Where I've shipped

AI / Software Engineer Intern

Dassault Systèmes Mar – Aug 2026

Built an end-to-end GraphRAG assistant over a skills ontology (ESCO/SKOS): natural-language to SPARQL, an ontology embedding pipeline in Java with an in-memory vector store, and a conversational panel inside the 3DEXPERIENCE Ontology Explorer.

AI Engineer Intern

BNP Paribas Mar – Jun 2025

Built a multi-agent RAG assistant for internal knowledge access doing semantic search over 20K+ documents with BGE multilingual embeddings, FAISS indexing, and a GPT model for answer generation.

Data Analyst & NLP Intern

ThynkTech Nov 2024 – Jan 2025

Built a document-clustering pipeline (TF-IDF + K-Means, scikit-learn, spaCy) over 500+ documents, surfacing recurring topics and the most-referenced resources.

Machine Learning Intern

SAA (Société Nationale d'Assurance) Mar – Jun 2024

Developed a Variational Recurrent Autoencoder in TensorFlow to detect anomalies in clients' historical records, reaching 94% accuracy and cutting manual data-cleaning effort.

projects

Five domains, one way of working

Knowledge graphs, neural architectures, computer vision, applied risk modelling, representation learning each one built rather than assembled from a tutorial.

Deep Learning · NLP · 2025

Transformer from Scratch

A full Transformer built in PyTorch with no high-level libraries, multi-head self-attention, positional encoding, and autoregressive text generation, implemented to understand every tensor rather than to call one.

PyTorchAttentionNLP
Applied ML · Risk & Fraud · 2024 1st prize · national

Credit Assessment Workflow

Built at Hack4Future with Société Générale and won first place nationally: an AI-assisted credit workflow chaining document analysis, cross-document consistency checking, and ML fraud detection into a single risk decision.

Pythonscikit-learnDocument AIAnomaly Detection
Representation Learning · 2026

Neural Feature Learning Study

A study on multi-model feature fusion: combining deep feature extraction with representation learning to push classification performance past what any single backbone reached on its own.

Also worth a look

recommender systems · 2026

Food Planning App

A deployed meal-planning application built on recommendation algorithms and REST APIs, designed around how people actually eat.

2nd place · 2023

IEEE Hackathon

An intelligent student assistant bringing personalized recommendations, resource aggregation, and productivity tools into one app.

thesis · 2025

Hybrid Intelligent Assistant

Engineering thesis: a multi-agent architecture for contextual reasoning and information retrieval, graded with high honors.

off the clock

Idir when i don't do AI ;)

I like people, trading traditions, and finding out what makes a place itself either it's the food, the customs, the small specifics you only ever learn from someone who grew up there. Most of what I know outside engineering came from a conversation rather than a book.

national champion

Swimming

800m finswimming, national title and also Lifeguard certification. Years of early mornings in a pool teach the one thing that transfers everywhere: showing up on the days you don't feel like it.

Video games

Genshin Impact mostly part decompression, part puzzle box. A good game hands you a system whose rules you have to reverse-engineer and an incredible storyline on top of it.

Piano

Six years of it. It didn't stick in the end, but the habit of reading something structured and turning it into something that sounds right did.

Animation

Disney, cartoons, the whole catalogue. I've made peace with the fact that the inner child isn't going anywhere and honestly, it's good company.

Let's talk

Looking for a full-time AI/ML engineering role from September 2026. If your team works on retrieval, knowledge graphs, or getting models into production, I'd like to hear about it.
