I am João Vitor Bermal Santaniello, a software engineer with an MBA in Software Engineering from USP/Esalq, shipping production software since 2020. Day to day I build data systems, dashboards, web platforms and automations for water, energy, healthcare and telecom companies, and I now work AI-first with Claude Code, reviewing everything it writes.
I am also a musician with a background in interface design. That combination changes the result: a brand designed with the rigor of a digital product, and a store built by someone who designs the experience, not only the code.
Tell me what you want to create. I reply within one business day with the next steps.
