Contribute to all phases of the development lifecycle: concept, design, build, deploy, test, release to app stores, and support.
Diagnose performance issues, fix bugs (including crashes and ANRs) to increase the functionality of the application
Write well-designed, testable, efficient code
Ensure designs are in compliance with specifications
Prepare and produce releases of software components
Support continuous improvement by investigating alternatives and technologies and presenting these for architectural review
Collaborate with team members (product managers, developers, designers) to brainstorm about new features and functionalities.
