A little about me / 02
Learning how things work — then building something with them.
I’m Aldi Setiadi Putra, an Information Systems student with a growing interest in software development and the systems behind digital products.
My projects range from interactive personality-style tests to small browser utilities for encoding, text processing, cryptography-related tasks, and web development. I use them to practise, experiment with ideas, and make useful tools accessible through a simple interface.
This portfolio is a curated selection, not the complete list. I keep adding experiments and projects as I learn, so the best place to explore everything is aldi.qzz.io.
Keep exploring
