- Contribute across the full stack, including front-end UI development and back-end application logic
- Collaborate with engineers, product owners, and stakeholders to deliver solutions aligned with evolving needs
- Adapt quickly to shifting priorities, new feature requests, and changing requirements
- Participate in architectural discussions related to scalability, performance, and maintainability
- Write clean, maintainable, and well-tested code following best practices
- Participate in code reviews and uphold quality standards
- Troubleshoot, debug, and resolve application issues
