Paulo Emmanuel Ferreira De Oliveira

Hello! I'm Paulo Emmanuel, a Software Engineer specialized in Backend solutions with four years of solid experience in the Fintech sector, particularly in building scalable, high-performance systems that support complex cross-border transactions.

My core technical expertise lies in PHP (Laravel), Java, and Kotlin. I am committed to technical excellence, architectural robustness, and driving measurable business results.

I leverage modern architectural patterns like Hexagonal Architecture and Domain-Driven Design (DDD) , along with Microservices, to deliver robust corporate systems.

I am highly proficient with Docker, CI/CD, and Jenkins for reliable and efficient delivery. I have successfully implemented critical integrations for corporate systems, including SSO, ERP Newcon4, DocuSign, and Sensedia, while developing robust RESTful APIs.

Beyond development, I actively apply Artificial Intelligence (LLMs) to drive efficiency in daily workflows. This includes automating project analysis during PHP version migrations and creating standardized prompts to generate unit tests and QA data, significantly increasing team efficiency.

Furthermore, I have acted as a project reference. I successfully refactored legacy code and optimized performance , while also mentoring two junior developers to promote clean code and best practices.
