🚀Career Journey
I started as a Backend Engineer, then evolved into a Full-Stack Developer building end-to-end web applications. I am currently working as a DevOps Engineer at mgm Technologies Partner - a software development partner serving international clients across multiple industries and countries.

🌍Language Journey
As an extroverted person, I have always been passionate about connecting with people from different cultures. Through traveling, working internationally, and attending global events, I have met and made friends with people from over 50 countries around the world. English has been my primary tool for global communication — from daily work with international clients to building friendships across continents. I also speak French at a conversational level, which I picked up through self-study and cultural exchange.

🎹Piano Journey
Beyond coding, music is my creative outlet. I have been teaching myself piano, exploring everything from classical pieces to modern compositions. Playing piano helps me stay focused, develop patience, and find balance between the analytical and creative sides of my mind — skills that translate directly into better problem-solving as an engineer.
