02 THE PERSON BEHIND THE CODE

A work in progress.
By choice.

An independent mind.
A practical approach.

I'm Kennedh, a full stack developer based in Criciúma, Brazil. I like understanding how things work — especially when they don't.

My path started in technical support and computer maintenance. At Agrosys, that curiosity grew into work with enterprise systems, Progress ABL and ERP routines. Today, I bring that same investigative mindset to development.

Outside work, I build tools in Python, explore JavaScript and study AI. I learn by doing: a useful project, a difficult question and another commit.
