Leonel in a few words

I am a lover of details, that is why my specialty is the front end, I have always been a detail oriented person, I really LOVE (yes in capital letters) developing software.

I started when I was a kid I was 14 years old making my first website for a science project related to fish (I love the fish too).

Throughout my career I have developed many projects, ERP, Customized Systems for companies, Software in the Health Tech sector, Education, Banking, Public Administrations, Mobile Apps, Marketing Platform, with different types of clients in the United States, UK, Holland, Spain , Salvador, etc.

I enjoy each of the processes of software development, I have experience in backend, frontend, database, mobile apps, testing (yes, I am a dev who likes to test his software).

Humans like hight quality in life, food , work, health, why not also have quality software? I use a lot of tools regarding QA ESLint Git Hooks, Prettier, Platforms like SonarQube, Unit and Integration Tests, because if we are going to do something, we must do it the right way :)

I have always worked with excellent communication and agile methodologies.
