For each technology: where I have put it into practice (work-study, school, team project or personal project) and, where relevant, the modules taken at Efrei. Courses lay the foundations; work-study and projects put them to use.

AIArtificial intelligence
AI, a real work tool
It doesn't replace reasoning: it speeds it up, provided you know how to direct it and check what it produces.
Prompt engineering
Frame the context, give examples, break a request into steps, iterate: the quality of the answer depends on the quality of the question.
Several tools, not just one
I can use most of the AIs on the market and I choose depending on the task: code, writing, research, analysis, knowing the strengths and limits of each.
Understanding, not just using
I'm interested in what happens behind the scenes: how a model produces its answer, why it can be wrong, how to check. I review and test what it produces.
An AI culture in the company
At SGP, the AI culture is advanced: regular briefings, meetings, feedback among colleagues. Added to my personal practice and my training, it clearly speeds up my daily work.
BUT in Computer Science framework
Three skills, and where I lived them
The BUT is structured around skills, with professional situations (PS), critical learning outcomes (CLO) and resources. For each one, what I actually did.
Building an application
Design, develop, test and integrate a complete application while respecting the client's needs, ergonomics and good programming practices.
Professional situations
Build a software application
Evolve an existing application
Maintain an application in operational conditions
Critical learning outcomes
Draw up and implement functional and non-functional specifications
Apply accessibility and ergonomics principles
Adopt good design and programming practices
Check and validate the quality of the application through tests
Associated resources
Web and mobile development
Object-oriented programming and systems
Software architecture
Development quality and testing methods
In my background · On S-Print v4 (SGP): React/TypeScript pages and components, Symfony endpoints, tests. At the prefecture: rebuilding and putting the booking site into production.
Optimising applications
Analyse and improve program performance while taking constraints (time, memory, consumption) and environmental impact into account.
Professional situations
Improve performance in constrained contexts
Limit the environmental impact of an application
Implement suitable and innovative solutions
Critical learning outcomes
Choose suitable complex data structures
Use advanced algorithmic techniques (optimisation, AI…)
Assess the environmental and societal impact of a solution
Profile, analyse and justify the behaviour of code
In my background · Dijkstra and Bellman-Ford on the RATP metro, Kalman filters and tile cache in PlanesView, a memory crash of the tests under WSL reported to the team.
Working in an IT team
Collaborate effectively within a project team with clear communication, agile methods and collaborative management.
Professional situations

Draw up, manage and pass on information
Launch and steer a project collaboratively
Critical learning outcomes
