• Build and maintain web applications using React, Next.js, and TypeScript.
• Develop cross-platform mobile applications using Flutter and Dart for Android and iOS.
• Deliver product features from UI/UX designs and product requirements through development, testing, release, and production support.
• Translate product requirements and designs into well-structured, testable, and production-ready code.
• Develop core user journeys across web and mobile, ensuring a consistent experience across platforms.
• Build responsive, accessible, and high-performing interfaces for different devices and network conditions.
• Optimize application performance, stability, loading time, and overall user experience.

2. AI-native and Coding Agent Development

• Use coding agents and AI-assisted development tools such as Cursor, GitHub Copilot, Claude Code, or equivalent solutions for code generation, refactoring, debugging, documentation, and repetitive engineering tasks.
• Design effective prompts, context, rules, and development workflows so that coding agents produce code aligned with product requirements, project architecture, and engineering conventions.
• Review, test, correct, and improve AI-generated code before merging or releasing it.
• Identify security, performance, maintainability, and architectural risks in AI-generated code.
• Balance development speed with code quality, testing coverage, maintainability, and long-term product stability.
• Evaluate new AI-assisted engineering tools and recommend practical applications for the development team.

3. System Integration and Product Quality

• Integrate web and mobile applications with backend services through REST or gRPC APIs.
• Implement authentication, authorization, state management, error handling, and end-to-end data flows.
• Write and maintain unit, integration, and end-to-end tests for core product journeys.
• Debug application issues and identify root causes across frontend, mobile, API, and integration layers.
• Participate in code reviews, CI/CD pipelines, release processes, and production troubleshooting.
• Ensure stable user experiences across supported browsers, operating systems, devices, and screen sizes.
• Collaborate with QC Engineers to define test scenarios and resolve issues before release.

4. Engineering Standards and Collaboration

• Develop and share best practices, reusable prompts, templates, and guidelines for coding-agent-assisted development.
• Contribute to frontend and mobile architecture, coding standards, reusable components, and shared libraries.
• Collaborate closely with Product Owners, UX/UI Designers, Backend Engineers, QC Engineers, and SRE/DevOps Engineers throughout the product development lifecycle.
• Communicate technical decisions, risks, dependencies, and trade-offs clearly to relevant stakeholders.
