• Manage the full development cycle from analyzing complex business requirements to production deployment and maintenance, ensuring end-to-end technical solutions.
• Implement and enforce clean, maintainable, and well-documented code following best practices (DDD, Clean Architecture, Design Patterns) and established coding standards.
• Participate actively in code reviews, providing constructive feedback and upholding code quality across all services.
• Proactively identify and resolve performance bottlenecks, architectural deficiencies (e.g., event loopholes), and technical debt.

• Contribute to the continuous improvement of CI/CD pipelines, automated testing (unit, integration, e2e), development processes, and observability (Grafana, OpenTelemetry)
