About me

👋 Hi, I am Erick, a brazilian senior web developer and software architect with over 28 years carrier of non-stop programming. I have a degree in telecommunications engineering (bachelor's degree) and have been developing software since I was 15 years old.
👀 I'm a father, married and already traveled to more than 30 countries around the world. I am interested in sharing my knowledge to help other programmers and also being helped when I see difficult paths in the way.
🌱 I’m currently learning NFC, ERC tokens (smart contracts implementations), different types of ORMs, automated test tools, Flutter and DART, RabbitMQ and Memcached.
💞️ I’m looking to collaborate on back-end projects (.NET Core or .NET 5.0+), SQL Server or Postgres issues and some WebRTC projects (screensharing and videoconferences).
