Ynov Campus
Teacher in Master's classes
Teaching and sharing knowledge have always been a passion of mine. I now teach at Ynov Campus in Sophia-Antipolis, a higher education institution, in the Master's program, on web development and software testing.

Smart-Chain
Fullstack developer, Web3 & AI
A Paris startup in the blockchain and artificial intelligence space, where I developed several products, including one for the French Alternative Energies and Atomic Energy Commission (CEA), among other prestigious projects.
Fullstack developer on a cloud infrastructure, mainly using NodeJS, TypeScript, React, Next, Prisma, PostgreSQL, WebSocket, and queuing, to build web applications interacting with:
- blockchains: smart contract calls, indexing, IPFS;
- AI models I developed in-house in computer vision (CNN, GAN, ViTransformers) and on tabular data (RNN, LSTM): classification, detection, segmentation, and regression;
- LLMs such as those from OpenAI and more recently Mistral AI: assistants, prompting, fine-tuning, and RAG.

Frontend, then backend developer
I worked on the first marketplace in Switzerland, in an English-speaking company.
One year as a frontend developer with React hooks and TypeScript based on hydration, using Material-UI, React-Query, and Redux.
Then one year as a backend developer with Java Spring, .NET, Kafka, PostgreSQL, and SQL Server, on a Kubernetes infrastructure managing our microservices, with Scrum.
I also improved my English through daily interactions with my English-speaking colleagues and various presentations.

Infotel
Java & machine learning developer
I designed desktop software in Java with a machine learning component, used to retrieve metadata from patent documents of the European Patent Office with the CRF (Conditional Random Fields) method.
I also honed my skills in software architecture through object-oriented programming and many pair-programming sessions with my mentor.

03 /About
Today, independence
I have been able to grow professionally in various environments, from established companies to startups, as well as in teaching.
I have met many brilliant minds, worked with a wide range of technologies, followed various work methodologies, and adapted to different work paces.
I have immersed myself in, analyzed, and differentiated various practices with a critical perspective, allowing me to better understand their advantages and drawbacks and thus grasp professional challenges.
With the strength of my experiences, I am now pursuing my career independently, with an ever-growing appetite for technology and challenges in my areas of expertise: full-stack web, Web 3.0, and artificial intelligence, while always remaining committed to teaching.
Education
I undertook advanced studies in software development to enhance and certify the skills I acquired as a self-taught developer, obtaining my Master's degree in software development with honors.
During this course at Simplon, Campus ID, and Sophia Ynov Campus, I specialized in web development, software testing, software architecture, artificial intelligence, and blockchain.
04 /Beyond code
My free time? Between good times and technology watch
I am quite a bon vivant: I love my family, outings with friends, traveling, music, sports, reading, video games, series, and movies, like many people.
But my old habits often catch up with me, as I am also passionate about technology watch, research, and developing personal projects.
That is why you will find projects and articles on this site. I spared you the drafts, which I can't even count (my GitHub is a testament to this): I love to explore, optimize, create, share, and learn.
I am sensitive to software architecture and the art of building sustainable, elegant, and efficient solutions for the future.
Resilience, flexibility, maintainability, security, and optimization, balanced with the compromises of production, time, and money, as well as understanding their stakes, guide my professional daily life and conscience.
I have a particular fondness for artificial intelligence and all the work that revolves around it.
Philosophy
“Learn, experiment, contribute, help, and feel; whether you fail or succeed, it will serve one day or another, both technically and humanly.”
