Available for a 3-month international internship · 3 years of work-study · Efrei × SGP
I'm Alexandre,
full-stack dev.
I build web and mobile applications end to end, from the API to the interface. I'm an engineering student at Efrei Paris and, on a work-study contract at the Société des Grands Projets (the Grand Paris Express), I take part in the v4 rebuild of S-Print, the platform where SGP's partners declare their data.

S-Print v4: the rebuild I'm working on
SGP is building the Grand Paris Express. To manage its contracts, it gives its partners S-Print: a portal to enter and check their declarative data (economic activity, jobs created, construction-site safety). I take part in the rebuild of its third version, which replaces Excel files with a user-friendly interface, controlled reference data and an automatic feed into the Cockpit analysis tool. Here are its five main areas, drawn as a metro line.
Economic footprint
Contract holders declare the economic and social impact of their contracts: at least 20% of the amount for small businesses and 10% of the hours for people far from employment.

What I'm most proud of
My work-study rebuild, a personal project that holds up, and a school platform that goes all the way down to the infrastructure.
S-Print v4
The rebuild of the Société des Grands Projets' platform where contract holders file their declarations, from Java/Vue to Symfony and React.
PersonalPlanesView
All air traffic live on a photorealistic globe, and the view from the cockpit of any aircraft.
School project · teamWheeltrip
A complete mobility platform for people with reduced mobility: mobile app, web, API, databases and infrastructure.
About
Engineering student, working developer
After two years of work-study in the SINUM department of the Val-de-Marne prefecture, where I worked on web, mobile and databases, I earned my BUT in Computer Science at the IUT of Créteil-Vitry. Since September 2025, I've been preparing the Efrei Paris engineering degree, Software and Information Systems major, over three years of work-study.
I can work alone — two years of full autonomy at the prefecture — as well as in a team, at school and at SGP. And I use AI every day, with method, to go faster without losing rigour. Alone and in a team → · How I work with AI →
I split my week between Efrei and SGP. At school, I consolidate the fundamentals: software engineering, algorithmics, databases. At work, I deliver: React/TypeScript pages, Symfony services, tests, code reviews, and I take turns as scrum master.

Beyond the code
Rigor, perseverance, curiosity
Four years of weight training, bouldering, wildlife photography and involvement in the Efrei climbing association: what I learned there, I apply to my work.
