I started working with Ruby Back in 2005 making games with RPG maker tool, of course this was only for enterteinment. This took me to learn eventually rails to create websites and from there i have been working with this awesome tool in different projects through my career. I worked for multiple clients as a freelancer in Mexico, right now I'm running my own dev business to make better software. We try to focus on quality rather than quantity. Since I love to teach i come here as a teacher and as a student i like to learn new things and show some cool tricks.

As a Technical Leader and Senior Software Engineer I was in charge of making code reviews for my team, organize the backlog on Pivotal tracker, organize the iteration planning and retrospective calls, Advice on Arquitectural decisions, and develop features and fix bugs on the platform, Backend and Frontend wise with 3 different technologies: Ruby on Rails API, Sveltejs and Angularjs.

One of my responsibilities in the company was to do the software release through Github actions. by overseeing the correct deployment and making sure that all step finished correctly.

As a Software engineer I worked through the application to maintain the code standards high and the correct usage of testing frameworks (Rspec, Vitest) with each release.

We built documentation for each feature ticket that included designs with figma, technical notes in notion, product notes in notion and well written acceptance criterias. As a Technical Leader one of my responsibilities was to pursue that all this points were updated within each ticket. and be able to answer technical questions to the team.
