Who am I?

About me

I'm a Systems Engineer with 8+ years of experience as a Senior Full-Stack Developer. I specialize in backend with Java (Spring Boot, Jakarta RS) and PHP (Laravel), and frontend with Vue 3, React and Angular.

I currently lead development teams at Thomas Processing & System SAS, where I define architectures, conduct code reviews, and deliver high-quality software solutions. I also have strong experience with relational databases (MySQL, PostgreSQL, IBM DB2) and Linux server administration.

I'm passionate about well-crafted software engineering: clean code, robust systems, and high-performance teams.
