Zipizapp

Independent developer

Apps, websites, and other experiments

I build personal projects across different areas, blending product, design, and code. Some start from practical needs and others from curiosity, but all of them aim to solve something real or explore new ideas.

These are my projects

Apps and websites I have been building and improving over time.
