About

Fresh out of ECE Paris, Data & AI track. I got my start at Renault Group, in data engineering, then at Wakam, in full stack development. I'm convinced hand-coding has less and less of a future, AI already automates a good share of it, and what really matters is knowing how to make the right calls: understanding the data, the architecture, the product. That's what's drawing me toward a role in data or AI, a sector with real staying power. Outside of client work, I build and host my own projects, down to the server they run on, mostly out of curiosity.

Projects

A few personal projects I build and host myself, plus some group projects from school.

GVVB logo

GVVB

gvvb.fr

The volleyball club's old site was outdated, badly organized and confusing. I volunteered to rebuild it from scratch, design to deployment.

Next.jsReact

I keep it updated all season long, results, photos, news, like the club's own little blog.

Metron-pricing logo

Metron-pricing

metron-pricing.fr

My graduation project, built with a team of six. Most of the group majored in finance and worked on the pricing and arbitrage models, I handled the site, front and back.

FastAPIReactSupabaseQuantLibyfinance

The most technical project of the bunch, and my first real taste of working with people who don't code.

Rubik's Clock logo

Rubik's Clock

rubiksclock.fr

I learned to solve the Rubik's Clock on YouTube. Once I had the method down I wanted to go fast, but beginner technique meant bad times. I fell down the speedcubing rabbit hole, algorithms, phases, techniques, and wanted a real timer for myself. So I built one.

Next.js

A timer built for me, with the completion algorithms always at hand.

Soirée Popcorn logo

Soirée Popcorn

soireepopcorn.fr

Picking a movie as a family is always the same struggle. The Tinder-style swipe idea was already floating around school and social media, I made it mine to practice, and to try out Claude's SuperPowers plugin along the way.

Next.js

A simple project on the data side, more about testing a new tool than impressing anyone.

TravelAI

github.com/Djo1711/travelai

A two-person school project: a trip-itinerary recommender that adapts to budget and time available. My teammate handled the geospatial data (OSM, a graph of places), I built the recommendation model, the API and the interface.

PyTorch GeometricFastAPIStreamlitGeoPandas

My first real ML project: a Graph Attention Network trained to recommend places based on user context.

Semantic Analysis

github.com/Djo1711/semantic-analysis-project-fork

A group school project: a tool that reads a user's free-text answers and recommends a job profile and key skills. I focused on the semantic engine, SBERT sentence embeddings combined with TF-IDF to score closeness to each competency.

Sentence-BERTscikit-learnStreamlit

My first real dive into NLP: comparing free text against a skills database using sentence embeddings.

IMDB + Kafka

github.com/Djo1711/imdb-kafka-bigdata

A group school project: analysis of the IMDB dataset (millions of movies and people), plus a Kafka pipeline that streams Wikipedia edits on popular movies and actors in real time to spot activity spikes.

PandasApache KafkaDocker

My first real taste of Big Data: handling huge datasets and real-time streams with the same tools used in production.

Self-hosted infrastructure

I was running everything for free on Vercel, until curiosity won: I wanted my own domain names. With Claude by my side, I built my own infra, Cloudflare, Traefik, Docker, Coolify, on a Hetzner VPS. I provision, deploy and monitor it all solo, and this portfolio runs on the same stack.
