- Strong expertise in building scalable backend services and RESTful APIs
- Track record of writing clean, maintainable code with comprehensive test coverage
- Strong understanding of security best practices and experience building secure systems
- Excellent problem-solving skills and ability to break down complex requirements into manageable tasks
- Strong communication skills and ability to work effectively with cross-functional teams
