• Design & Build: Support and enhance existing Android applications while architecting and implementing future cross-platform mobile applications using React Native and TypeScript, following best practices for performance, accessibility, and maintainability.
• Mobile Architecture: Deliver features within both native Android and React Native environments while promoting scalable architecture patterns and long-term maintainability.
• Integration & Networking: Implement robust API integrations and handle authentication and authorization for secure, scalable mobile applications.
• AI Agentic–First Engineering
• Develop using AI-assisted workflows with tools such as GitHub Copilot and Claude to accelerate coding, refactoring, documentation, and test generation.
• Leverage agentic patterns for multi-step tasks such as feature scaffolding, modernization efforts, UI generation, dependency analysis, and CI/CD interactions, with appropriate human oversight.
• Apply AI-assisted pull request reviews and security scanning, validating outputs with strong engineering judgment and secure-by-design principles.
• Continuously evaluate and improve the use of AI tools across the SDLC to increase throughput, quality, and developer experience.
• Quality, Delivery & Operations
