From design to validation
I connect the data model, application logic, interface and functional tests. That is the core of the Application Development track, and what I want to practise during an internship.

Application Development track: design, development and validation
I design and build web and software applications, from data modelling to the user interface. I am looking for an internship to strengthen these skills within a development team.
Profile
Second-year student in a University Bachelor of Technology (BUT) in Computer Science at IUT de Metz, on the Application Development track: design, development and validation. I enjoy building complete applications: a clean data model, clear logic and a polished interface.

- Looking for an internship
- Programme
- BUT Computer Science · 2nd year
- Area
- Metz, France
- Core stack
- React, Next.js, TypeScript, SQL
Comfortable with data
Conceptual and logical data models, constraints, foreign keys, joins and aggregations. Data never stays theoretical.
A reliable junior profile
Pair work, Git, reports, presentations, organisation. I aim to learn fast without overselling my level.
Projects
Projects carried out at the IUT, from data modelling to the interface, with the approach detailed for each one.
Web project · Completed · 2024-2025
Subscription management web application
Web application to track and manage active subscriptions, from the SQL database to a responsive interface. Built in pairs as part of the BUT programme.

- Conceptual and logical data modelling with Looping.
- Tables, constraints and foreign keys in SQL.
- Joins, aggregations and subqueries.
- Visualisations and Excel/CSV exports to monitor the data.
Outcome
A structured report with models, tables, constraints, queries and Excel/CSV exports.

macOS app · Release candidate · 2026
CoreTend — macOS cleanup and maintenance
Native macOS app (SwiftUI, Swift 6) to clean up, monitor and audit a Mac locally: storage, duplicates, large files, system performance, IntegrityCore, provenance, quarantine, signatures and launch items. Personal project, built and maintained solo.
View the project- Modular architecture across 9 Swift packages (scan engines, security, system metrics, SQLite persistence).
- Local scans with no account or telemetry; only an explicitly requested update check reads the public HTTPS manifest.
- IntegrityCore audits quarantine, provenance, signatures, Gatekeeper, LaunchAgents and LaunchDaemons; no antivirus feature.
- Stress-test suite (10,000+ files, deep directory trees) alongside the unit tests.
Outcome
Full automated test suite (passing in the repository and on a clean clone), warning-free release build, public bilingual FR/EN site and distribution state shown without hiding Gatekeeper. Unsigned/not notarized (needs Developer ID); the exact version is stated on the project page.
