• 4+ years designing and developing RESTful APIs at scale.
• 3+ years of hands-on TDD: writing unit and integration tests before coding.

• Strong experience in relational or NoSQL database schema design and modeling.
• Proven ownership of technical decisions and ability to justify design trade-offs.
• Excellent technical communication and documentation skills.
