At Softtek, I develop modular, user-experience-oriented interfaces with React and Next.js for multiple concurrent client applications. I also design and implement REST APIs and backend services using Java, Spring Boot, and Quarkus.

At Softtek, I connect applications to SQL Server and MySQL, and manage deployments and cloud environments using Google Cloud Platform. I also automate pipelines with GitLab CI/CD.
