Back to original languageAbout Johann
Senior full-stack architect and developer, I design web applications and define the technical stack based on the client's needs and the team's skills. I enjoy coding in Kotlin, Java, Node.js, Typescript using frameworks and libraries like Spring, Spring Boot, Express, Angular, React. Experienced with relational databases like PostgreSQL, I also have experience in NoSQL (MongoDB).
I pay particular attention to:
- Business needs
- Application design: Hexagonal Architecture, Clean Architecture
- Code quality: Clean Code, performance, unit tests, pull requests
- Process automation (DevOps): Continuous integration and deployment via Bitbucket CI and GitLab CI
If we work together, I will bring my technical and interpersonal skills and help you find solutions to the problems we encounter.
Oh, and I almost forgot, the SCRUM framework holds no secrets for me; I've been practicing it for several years and I am a certified Scrum Master.
