Back to original languageAbout Maxime
Hello,
I'm Maxime, a developer for over 10 years, specializing in backend systems, high-performance applications, and Linux environments.
I have worked in various environments: logistics, investment banking, payment processing, software publishing, and application development.
Today, as an independent contractor, I assist companies in designing, improving, and optimizing their backend and application systems.
I can help with:
- Designing or developing a reliable backend: APIs, authentication, data aggregation, business services.
- Auditing existing architecture.
- Improving the performance of an application or API.
- Resolving infrastructure or deployment issues.
- Assisting with technological transitions.
- Implementing simple, robust solutions tailored to your constraints.
Since becoming independent, I have focused particularly on API design, authentication systems, databases, Linux infrastructure, performance, and lightweight distributed systems.
I primarily use C/C++, Go, OCaml, SQL, Linux, Docker, and NGINX. My past experience in .NET environments also allows me to work on C# projects.
I enjoy working on pragmatic solutions: clear code, understandable architecture, measurable performance, and easy-to-maintain infrastructure.
If you have an application project to structure, a backend to stabilize, an API to optimize, or an existing system to refactor cleanly, I can help you lay a solid technical foundation.
