Built the backend for Makisu, a financial-tracking tool for CAERP (an open-source management platform for French business-and-employment cooperatives), replacing a manual Excel workflow.

• Developed a Java/Spring Boot REST API with endpoints to log monthly user counts per cooperative instance.
• Built endpoints to generate financial recaps and forecast next year's budget.
• Added a scheduled job to fully automate the monthly user-count readings.
• Followed a hexagonal architecture and DDD, with JUnit and Cucumber test coverage.

Built a web app for a TBI research team to configure and run gas-liquid reactor microbiology simulations, separating a researcher's calculation engine from a reusable graphical interface.

• Designed and developed a Node.js REST backend and a TypeScript frontend to manage reactors, species, and flow-based simulations.
• Built an interactive node-based flow editor so users can visually design reactor networks, feeds, and fluid flows.

• Covers the full software lifecycle through project-based coursework, from system design to deployment.
• Tracks offered from year two: application development, secure application deployment, and data management.

• Completed the MIC (Modélisation Informatique et Communication) pre-orientation after the first year.
• Built a Python implementation of circular Nim games (combinatorial game theory) with unit tests, playable through a Discord bot written with discord.py.
• Designed and built an analog signal chain for a multiplayer laser-tag game: DFT-based frequency discrimination, a Chebyshev anti-aliasing filter, and a photodiode receiver circuit, validated on an oscilloscope.
• Left the engineering program during the third year.
