// about me

Beyond the code

I've been developing software professionally for 2 years, specializing in solving operational bottlenecks for businesses. I enjoy finding the perfect architecture for a business to scale without friction.

However, my way of understanding the world is not limited to programming logic. Music, photography, and audiovisual creation are the channels where I express my most creative and human side.

I aspire to establish myself as a YouTube creator and compose my own music, merging my technical vision with my artistic sensibility.
