Freelancer profile translated to English.
Back to original languageAbout Adrien
I come from web development, which I discovered in 2011. For the past 6 years, I have been specializing in Go, particularly for web backends and microservices. I also have good experience with IoT technologies; through my personal projects, I have learned a lot, and this field interests me greatly.
I have about 4 years of experience in IT consulting firms and 3 years as a freelancer, where I have worked in various domains:
- Creating a modular system in Angular 8 for maritime satellite boxes
- Frontend web with associated Android application
- Architecture and development of iOS applications in C++/Qt for aeronautics
- Project management for a small team
- Use of agile methodologies and client relations
- Refactoring and architecture of a microservices system
Above all, I believe my broadest background comes from my interest in IT through the numerous personal projects I developed alongside my studies (from middle school to the end of my master's degree). It is thanks to these experiences in particular that I developed my interest in code "maintainability," a point I am very attached to; because in my eyes, it is the major flaw of many software products on the market today. This period also taught me to work autonomously and to develop my versatility: graphic design and web design, fullstack development, being proactive, and having a real interest in the health of the projects I develop.

- VygonEasyComMEDICALJanuary 2022 - Today (4 years and 5 months)Toulouse, FranceMedical project for a French company with an international reach. The project consists of a modern web system for managing fleets of nutrient pumps via the Internet. I developed the system's backend and set up the production environment.The backend is developed in Go and uses Docker. It exposes a REST API for the frontend and a WebSocket API to communicate with the pumps. A PostgreSQL database manages the various resources. Several systems have been implemented to ensure medical-grade security at different application levels, notably through the use of certificate chains, Argon2, mTLS, and JWT. The backend is fully tested with unit and integration tests (dockerized) to achieve maximum code coverage (+80%). I developed continuous integration and deployment mechanisms to provide the client with an up-to-date version throughout the development process.The REST API relies on the open-source aicra library, which I have been developing for several years.My work includes:- Backend: the backend with its 2 APIs.- Cert: a command-line tool for managing certificate chains, used as a library by the backend.- Package: a simplified execution environment for team members.- Setup: production environment.
