• API Design: Design and implement secure, RESTful APIs using .NET 6/8+, emphasizing "Clean Architecture" principles. 
• Database Optimization: Work with existing SQL databases to optimize queries, design efficient schemas, and ensure data integrity during the transition from legacy access patterns to modern ORM (Entity Framework Core) patterns. 
• Security & Compliance: Implement and maintain healthcare-specific security standards, including data encryption (at rest and in transit), HIPAA-compliant logging, and OAuth2/OpenID Connect authentication. 
• Technical Mentorship: Provide guidance to junior backend and frontend developers, performing rigorous code reviews to maintain high standards of code quality and maintainability.

• Testing: Experience with unit testing frameworks such as xUnit/NUnit for backend and Jasmine/Karma or Jest for frontend. 

Preferred Qualifications 

• Industry Experience: Minimum of 3 years working on Healthcare products, with a solid understanding of HIPAA regulations and PHI handling.
