    Comecei na área de desenvolvimento web através da Trybe, mas já tenho buscado outros aprendizados por conta própria por pesquisas e ler documentação de linguagens ou bibliotecas. Como aficionado pela tecnologia em geral essa área me chamou muito a atenção. Já tendo trabalhado em diversas funções fora do escopo de tecnologia, aprendi comunicação e trabalho em equipe trabalhando tanto em uma gráfica, a qual foi de forma informal e em telemarketing.
