During my experience at Origine Cycles, I worked on the development and improvement of the company's internal web services and e-commerce site.

My role was to strengthen the reliability of APIs, optimize back-end performance, and contribute to the overall quality of the tools used internally and by customers.

• Development and maintenance of internal APIs under Symfony

• Improvement and optimization of the multilingual system (i18n)

• Automation of internal processes, particularly through API integrations

• Bug fixing, stability improvement, and performance optimization

• Participation in the development of features for the e-commerce site

• Backend: PHP, Symfony, MySQL, SQL

• APIs: REST, external service integration

• Tools: GitLab, Postman, local environment (MAMP)

• Frontend (as needed): HTML, CSS, JavaScript

This experience allowed me to:

• Deepen my skills in back-end development and API design

• Work on a complex and feature-rich e-commerce environment

• Manage performance, security, and multilingual issues

• Contribute to the improvement of tools used daily by the company

During this project, I designed and developed a complete showcase website to centralize the various content of the Pause Casque collective. The goal was to provide a modern, high-performance, and user-friendly platform to showcase their podcasts and encourage community engagement.

• Implementation of a modern and responsive interface

• Automatic integration of episodes via the podcast's RSS feed

• Development of a support module for online donations via Stripe

• Performance optimization and user experience improvement

• Configuration and deployment of a reliable and scalable solution

• Frontend: ViteJs, React, Tailwind CSS

• Backend: Java, Spring Boot

• Payments: Stripe (online donations)

• APIs: RSS feed integration

• Tools: Git, Vercel, Render

This project allowed me to:

• Work on a complete UX/UI-oriented showcase website

• Integrate external services (RSS, Stripe) efficiently and securely

• Strengthen my front-end development skills with Next.js

• Support a real project autonomously, from design to production

During my internship at BanWaves, I had the opportunity to develop Payment Wall, a web application for centralized customer payment and invoicing management.

The application aims to provide a simple, high-performance, and secure solution, with several **key features**:

- Invoice viewing via a secure customer portal

- Online payment through Stripe and Coinbase integration

- Confidential and secure management of payment information

- Frontend: Next.js, Tailwind CSS -> for a fluid and responsive interface

- Backend: Spring Boot, Java, MariaDB -> for a robust and reliable API

- Payments: Stripe, Coinbase -> for online transaction management

- Security: Passwordless authentication with Auth.js

Outcome

This project allowed me to:

- Deepen my full-stack development skills

- Integrate complex and secure online payment solutions

- Improve user experience through modern and responsive design

- Manage a complete flow: from customer management to transaction.
