• Ensure delivered code meets defined defect and quality standards.
• Own specific modules or services across the stack, including documentation and maintainability.
• Review merge requests with structured, actionable feedback.
• Participate actively in architectural and design discussions.
• Identify and resolve technical debt within owned components.
• Debug and resolve production issues across UI, API, and data layers within agreed timelines.
• Mentor junior engineers through regular technical guidance sessions.
