Mineirama was born from the idea of a mining HUB providing not only low cost electricity but also custom mining hardware and cooling systems. We've created prototypes of proprietary GPU mining hardware and mineral oil dipped cooling systems. The company had migrated to Paraguay looking for electricity costs but unfortunately didn't got enough traction to continue its operations.

Sr Full-Stack Developer

• Nov 2016 - Nov 2017

I've built applications to the news portal using several technologies including C# & .NET, Node.js, React, Angular.js, Redis and MongoDB. I've created a new login system using MEAN stack and OAuth2.0 including a user portal where the user are able to change the newsletter and push notifications preferences. This project included an email and push notification (mobile & Chrome) sender made in Node.js, rabbitMQ and Redis that improved the time taken for the 18 million unique users/month to receive our pushes. I had a great challenge migrating a system from C to c# to forecast the future result of the COPOM meetings, where the government decides the target interest rate for the next few months.
