  • Apply Hexagonal Architecture, Domain-Driven Design (DDD), Clean Code, and SOLID principles
  • Implement authentication/authorization (JWT, OAuth), enforce data protection, and integrate code-quality/security tools (SonarQube)

Requirements:

  • Familiarity with AWS services (EC2, S3, CloudFront, Lambda)
  • Strong understanding of web security best practices (authentication, authorization, data encryption)
  • Experience with quality and security tooling (JWT, OAuth, SonarQube, Kiuwan)
  • Highly proactive
  • Excellent communicator and team player
  • Results-oriented, self-managed, and adaptable to shifting priorities
  • A genuine love for coding and continuous learning
