Back to original languageAbout Jean-Baptiste
Experienced developer in C++, Rust, and Python, I design reliable, high-performance, and maintainable software. My approach is centered on code quality: readability, automated testing, and optimized performance.
I enjoy teamwork, sharing knowledge, and passing on my expertise to help both the team and the project progress.
💼 What I bring:
- Maintainable code: clear architecture, precise documentation, and solid test coverage.
- Performance: fine-tuning algorithms and reducing memory/CPU consumption.
- Reliability: robust CI/CD pipeline, unit, and integration tests.
- Controlled AWS cloud costs: usage analysis, refactoring, and optimization to reduce bills without compromising performance.
- Team spirit: supporting developers, sharing best practices, and technical mentoring.
💡 My philosophy:
A good code is understandable, tested, and durable.
I favor efficient simplicity: every line must have a reason to exist.
And above all, a good project is first and foremost a collective adventure.
🤝 In summary:
If you are looking for a developer capable of delivering robust, clean, and performant code, advancing your team, and reducing your cloud operational costs, let's discuss your project!
