// BACKEND · CREATIVE DIRECTION · STREETWEAR
Hi, I'm João — a backend developer and creative director building systems and streetwear brands.
I build clean backend systems in C# and work on APIs and databases, while leading the creative direction of FANCY — my own streetwear brand. I like mixing logic, visuals and storytelling into projects that actually feel like something.

// About
Who I am
I’m a final-year student of the CTeSP in Information Systems Programming at Instituto Politécnico de Leiria, focused on backend development, C#, microcontrollers and web technologies.
I have hands-on experience with ESP32, Arduino, Raspberry Pi, Python, PHP, MariaDB and building APIs. I enjoy solving problems and turning ideas into working systems.
On the creative side, I’m the creative director of FANCY, my own streetwear brand. I design the visual world of the brand — from concepts and visual identity to product design, photography and campaigns — building collections that feel minimal, emotional and visually strong.
