Skills
Coding
Coding is the most important skill, I develop trying to keep the best and most efficient practices.
Design
As a frontend developer after this time I have trained my eye as a designer, knowing how to use white space, color theory, etc.
Empathy
Empathy is a difficult skill to train, I strive to empathize with the user and with any situation outside my environment to understand any need and response from people.
UX design
Designing user experiences by knowing how to empathize with the user becomes easier, I'm still constantly learning, but building interfaces and user routes excites me a lot.
