• Work within Agile practices (Scrum, CI/CD, automated testing) using Git-based workflows (branching, PRs, version control), participate in code reviews, and engage with quality tools such as SonarQube.
• Gain hands-on experience in cloud and containerized environments (Kubernetes, Docker, Terraform) and contribute to the development of RESTful and event-driven APIs with databases.
• Support teammates by sharing knowledge, welcoming feedback, and actively developing your understanding of best practices across the team.
• Participate in technical discussions, show curiosity toward emerging technologies, and contribute ideas for improving development processes.
• Collaborate with architects, product owners, designers, and fellow software engineers to help deliver seamless user experiences.
