Experience
EmCasa.com
http://www.emcasa.comAt EmCasa.com, I was co-founder and CTO. As such, I initially did everything from designing the logo to the MVP screens and implementing both the back-end (in Elixir/Phoenix) and the front-end (in React/Next.js).
Gradually, the team grew, and I moved toward managing the team, including the native app in React Native, and coded mostly on the front-end day to day.
The company was accelerated by the Harvard Business School and raised USD $1 million in seed money. Now it's serving tens of thousands of customers per month in the real estate space in Brazil.
