About

Hi, I'm Nahuel.

Nahuel Krowicki

Software / product engineer in Buenos Aires. 9+ years building products.

Journey

I built my career step by step: repairing computers and supporting customers, then managing IT infrastructure for a pharmacy chain, moving into freelance web development and senior fullstack roles at international companies, before building my own SaaS. Along the way I also led a few teams and projects.

That journey gave me a broad technical foundation. Alongside software engineering, I've studied networking (CCNA), Linux server administration, and ethical hacking, which gives me a full view of the whole path: from the moment a user clicks to how that request is processed on the other end.

I've worked as a Software Engineer at international companies like Alchemy and Ondo Finance (Web3), Sports Illustrated (sports media), Clockwork (finance), and 500 Global (venture capital). I was also part of Accenture, where I led a development team.

I enjoy working with diverse teams, understanding different perspectives, and connecting the needs of the business with what we build. I'm passionate about digital products, and I see AI as a great opportunity to accelerate development, experiment more, and bring to life ideas that used to be too costly.
