    I have 20 years of experience in developing applications, implementing Oracle technology, products, and services at customers; and publishing multi-media content about Oracle's PaaS security and idM for the community. In 2020, I started a new job at TOTVS as Software Development Specialist, for the Retail and Distribution LOB. I'm developing, documenting, training, supporting sales, architecting and techleading the TOTVS Omni channel product initiative in the Research & Development team. I consider myself a generalist, with experience in a variety of industries (during consulting days) throughout my career, but with deep experience in some areas such as security and cloud. My main professional characteristics are collaborative, learn-prone, hands-on and self-study. I'm used to work in a fast-paced and multi-disciplinary environment, where soft skills always count as much as technical skills. I'm passionate about new technology and how to apply them.
