Software Engineer
I work remotely for a US based company, as a Software Engineer, assigned to a client that has a CMS tool for e-commerce websites. Despite being a headless CMS, we also build the website interfaces for some of the final customers. In those projects, we used React for the interfaces, NextJs for SEO and server-side rendering, Typescript as the main language, Redux for managing application states, with Redux Thunk for asynchronous calls. In addition, we had several integrations with third-party tools, such as Algolia for filters and searches, Stripe for payments and the client's own APIs for managing products, orders and cart. The project was carried out in a CI/CD environment, deployed on AWS, with a team of around 10 developers.

Cyber Security Analyst / Back-end Developer
I worked as a Back-End Developer for a cybersecurity company, where my focus was to integrate several different tools and platforms in order to create automated flows to optimize activities towards information security. A big project I built was to make our SIEM (Security Information and Event Management) integrate with internal tools that we used. For that, I built an API in Node that listened to all the requests that came from our tools, filtered these requests according to the objective and provided the corresponding flows, all in real time. This project, after being put into production, saved countless hours of work for several analysts. I also made integrations for other flows and tools using Python, but they were smaller projects.
