Software Engineer


Gabriel's profile photo

with 6 years of experience focused on back-end development using Java, Node.js, and Python to build web applications, microservices, system integrations and jobs. On the front-end, I have hands-on experience with React, Vue.js, Angular, HTML, and CSS. During my career, I've worked building new projects, supporting production, and helping with continuous improvements, developing solid experiences in:


* Software architecture: monolithic and distributed systems (microservices), system design, component definition, cloud services (AWS), and communication between systems.


* High-performance and scalable software development: creation of API's with clear documentation and automated tests, delivering safe and performant solutions with concurrency and transaction control, and good design/code practices.


* Databases: modeling, queries, and operations in relational databases (Oracle, PostgreSQL, MySQL) and non-relational databases (Redis, DynamoDB).


* Collaboration with multidisciplinary teams: working in agile environments such as Scrum and helping solve critical issues in financial systems to keep operations running.


* Monitoring and logging: applying observability best practices to improve visibility and speed up incident detection and resolution.
