About

I’m João Thaira, founder of ThairaHub, the company that makes Thaira (thaira.ai). I’m building a SaaS alone with AI agents without quitting the job, and I write here about how that works in practice: building products with AI, getting a SaaS off the ground and running a Brazilian company while living in Germany.

I’ve worked in data and software for more than eight years. I started in Brazil, at Banco Inter and iFood (Movilepay), and since 2021 I’ve worked with European teams: Blue Avenir, Yilu (now Lufthansa Group), Proxify and Precis. I live in Düsseldorf. Before ThairaHub, I founded INFINIVAGAS, an AI job platform.

My story started as a maintenance technician. I made the move into tech on my own and graduated in Computer Engineering from Centro Universitário Una. Now I use that experience to show others the way: how to work for companies abroad and how to build products with AI. I also mentor professionals making that same move.
