Enforce coding standards and best practices. Conduct thorough code reviews, provide constructive feedback, and mentor junior developers to improve code quality, consistency, maintainability and adherence to industry best practices.
Identify and address performance bottlenecks across the application stack. Implement caching mechanisms, optimize database queries, and apply best practices for minimizing latency.
Apply security best practices, including data encryption, authentication, and authorization, while ensuring compliance with relevant industry standards and regulatory requirements.
Create comprehensive technical documentation, including architecture diagrams, API specifications, and deployment guides.
Education and Certifications
Bachelor of Science in Computer Science or an equivalent degree.
Experience / Skills Required
5+ years of backend development experience using Java.
Strong expertise in Spring Framework and Spring Boot, including dependency injection, RESTful services, and microservices architecture.
