What I'm looking for

Senior Software Engineer at product-based companies

I started my career in 2012 as a SysAdmin Linux, where I worked on tasks such as network administration, web server management, script development, and security. At the same time, I developed some simple apps/scripts to help me with my daily tasks using Ruby and Ruby and Rails.

By 2014, I had shifted my focus to software development and have since spent most of my career working with Ruby and Rails. I have also gained experience with other technologies, including Elixir, Vuejs, Reactjs, and RabbitMQ. Additionally, I have taken on leadership roles and served as a technical leader on several projects during my time as a software developer.
