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.

APP

DroPilot

Guitar harmony app · Voicings and progressions explorer

An app for guitarists who want to move beyond the same old chords and discover new ways to play the same progression—with more colour, movement, and musicality.

Explore different sounds for the same progression.
Practical, musical focus—not abstract theory.
Great for writing, studying, and trying new ideas.

Fast turn-based matches that are easy to understand.
Blend of luck, bluffing, and decision-making.
