Description

Versatile Full-Stack Developer with over 5 years of experience, I design and develop web and mobile applications from A to Z. My approach: understand your business needs to build simple, robust, and maintainable solutions.

My technical stack covers the entire chain: HTML5, CSS3, and JavaScript on the front-end, Python, Flask, and PHP on the back-end, SQLite and MySQL for databases. I am also comfortable with Android mobile development.

With over 20 projects delivered — management applications, business tools, blogs, showcase websites, media players — I work on both from-scratch projects and improvements to existing ones. Autonomous and rigorous, I quickly adapt to your technical and organizational constraints.

Feel free to contact me to discuss your project!
