Back to original languageAbout SĂ©bastien
I have 20 years of professional experience in software development. My areas of expertise are:
• CTO:
I have been CTO of several startups. I am involved in various types of missions:
- Team management / project management
- Tech Lead and software development consulting: architecture, implementation, testing, CI/CD, industrialization, monitoring, etc.
- Consulting for startup executives
- Project feasibility studies, budgeting
• HEAD OF AI / MACHINE LEARNING / DATA ENGINEERING:
I have led projects in data analysis, image recognition, NLP, and recommendation engines. Machine Learning, but not only: also Data Mining and entity recognition, for example.
- for Majelan, I worked on improving the semantic search engine: how to find podcasts that match what you like?
- I fully coded the wine recommendation IT system for Serjee (it learns your tastes when you tell it which bottles you like, and then recommends bottles you might buy because they should please you). Result: 430% increase in online sales
- I coded the wine bottle label recognition engine: take a photo of a bottle with your smartphone, and the wine in question is identified
• BACK-END DEVELOPMENT:
All types of systems and architectures, coded mainly in Python, which is my current preferred language, sometimes supplemented with C/C++ sections for performance needs. Web with database interfacing, of course, but also telecommunication systems, electronic signature applications, data integration, legacy code refactoring, etc.
I am professional, reliable (you'll see), passionate about new ideas and technologies, and committed to the success of your projects. Contact me and let's discuss our collaboration. Guaranteed response.
