About Swan
Since 2022, I've started working as a freelance software engineer alongside my studies (graduating from INSA Lyon in Software Engineering). I've worked with diverse clients, from individuals to large companies, and helped them build complete production-ready solutions.
My goal is to help transforming an idea into a complete solution, from designing the app, developing a clean and modern frontend as well as a robust backend, or automating the delivery with DevOps workflow.
So whether you need to strengthen a team, implement a new feature or even if you've just started growing an idea, I would be glad to join your project and bring my expertise!
What I can bring to your project:
- Bringing a concept into a deployed app by guiding you through all the thought process and decision making
- Iterating quickly and working in agile environments, to be sure to perfectly match your needs.
I’ve worked with diverse tech stacks over the years. On the backend, I mainly use:
- Java / Kotlin with Spring Boot
- Hibernate / JPA
- Flyway
- Testing tools (JUnit, Mockito, AssertJ, Test Containers)
On the frontend, I mostly work with:
- React.js
- Vue.js
- TypeScript
- Tailwind or Bootstrap
- SASS
Alongside my personal and professional projects, I've also gained experience working with diverse other stacks, both backend and frontend:
- PHP / Symfony
- Node.js / Express
- C# / ASP.NET / Blazor
- Python / Flask
- Angular
- Nuxt
On the DevOps side, I work with:
- Gitlab CI/CD for pipelines and image registry
- Docker for containerization
- Kubernetes, Helm and ArgoCD for containers orchestration
- Sentry for monitoring
- SonarQube for code quality measurements

I’m currently taking on new freelance projects, so feel free to reach out if you want to chat or learn more about me and my work!

Experience
- ECOSSIMFullstack Developer FreelanceMEDICALAugust 2022 - Today (3 years and 10 months)Lyon, FranceECOSSIM is a web platform dedicated to the simulation and training ofECOS(Objective Structured Clinical Examinations), which are used at the end of medical school to assess students' clinical skills.The project was born out of a collaboration with a medical intern who was looking for an interactive tool to help students practice alone or in small groups, in conditions similar to the real exam.I supported the client from initial design to production release, managing the entire project as full-stack developer and UX/UI designer. My responsibilities also included product consulting, setting up DevOps workflows, and ongoing maintenance.
Main achievements:
- Designed the entire interface in Figma, in close collaboration with the client. We defined user journeys and created responsive functional mockups.
- Developed the front end using Vue.js and Nuxt with server-side rendering to ensure better performance and SEO.
- Set up automated deployment with GitLab CI/CD, including continuous integration, testing, error monitoring via Sentry, and code quality analysis with SonarQube.
- Integrated Stripe for subscription management, offering multiple plans (monthly, one-time, and annual). Subscribed users are synced via Stripe webhooks.
- Built an interactive ECOS scenario system, allowing students to join training stations solo or in multiplayer mode, each playing a specific role (doctor, patient, evaluator). Each session is graded, commented on, recorded, and the results are presented in a personal dashboard with analytics.
- Added a flashcard module based on the spaced repetition method, supporting long-term retention of medical knowledge.
