Ivry-sur-Seine, France
GetCasa is a connected home application that aims to connect different connected products together in a single application. The project was launched by 2 people. We were then able to choose the technical environment of our choice. We decided to go with Golang with PostgreSQL for the database, as we were looking for a lightweight environment. The mobile application was made in Flutter. A showcase website had been started in React. Because the project started from scratch, I was able to manage the project from the ground up, user data management, creation of complete REST APIs.

Optionizr is a B2B company that offers an option service to e-commerce sites (like airlines, ticket sellers, etc.). I joined Optionizr to integrate a small team of 2 developers, which forced me to be versatile and touch all aspects of the application. By joining Optionizr, I was able to:
- Improve and refactor the back office, create tests, develop new API routes, improve existing code, add features (e.g., invoicing system, management of merchant interface customization, merchant product configuration),
- Develop the user interface, create new pages related to the new directed features,
- Be an important player in decision-making, development proposals,
- Manage new data,
Regarding the technical environment, Optionizr operated with Node.JS and MongoDB / Mongoose for the back-end. In web technologies, we simply used HTML5 / CSS3 / Bootstrap and EJS for content management.
