Freelancer profile translated to English.

Description

Implementing a solution is not about stacking libraries on top of each other and seeing if it stands. Studying and understanding the fundamentals of processes and technologies to create or improve solutions is my vision as an architect and technical expert.

With 20 years of experience, my knowledge covers a fairly wide spectrum: analysis and design (IAF), backend development (Java, NodeJS, PHP), mobile development (Android and IOS), definition and implementation of cloud infrastructure (AWS), security (TLS, X509...), Linux Debian and Ubuntu system expertise, cryptography (AES, RSA), protocol design, M2M interface, Android customization (AOSP), performance improvement of existing systems (Mysql, MariaDB, nginx, algorithmic complexity analysis...).

Do not hesitate to contact me for support on your future project or a production issue.
