• Experience working alongside lead developers to make code design, framework, integration, error handling, security, data modelling, and non-functional requirement decisions throughout delivery rather than limiting architecture involvement to high level design documents.
• Ability to define coding standards, review critical implementation choices and team output, enforce reusable patterns, challenge unnecessary complexity, and ensure consistent code quality. Able to connect individual features and the broader codebase to business outcomes while maintaining alignment with the approved solution design, security expectations, test strategy, and long-term maintainability goals.

• Experience partnering with DevOps engineers to define CI/CD pipeline configurations, deployment gates, infrastructure as code structures, environment promotion strategies, monitoring, logging, rollback approaches, and release readiness controls.
• Ability to create comprehensive technical documentation for APIs, architecture decisions, and operational procedures.
• Demonstrated ability to develop junior developers through practical coaching on AWS best practices, Node.js development patterns, code quality, and troubleshooting techniques.
