Summary

My daily challenge consists of learning at least one new thing. My professional experience covers primarily the banking industry, working with languages such as COBOL, C, JavaScript, and NonStop SQL, as well as the use of tools such as Tandem and Tuxedo servers. I've taken part in all the stages of projects with methodologies such as agile and waterfall. It's worth mentioning that I've worked in the systems support area for companies experienced in marketing. Also, I'm currently learning about Microservices, API programming and GO. My three highlights are proactivity, loyalty and teamwork communication.
