• Secure API Development: Architect and secure RESTful or GraphQL APIs, ensuring strict protection against vulnerabilities like injection and broken object-level authorization
• Cloud Infrastructure: Deploy and manage application components natively within AWS using containerized environments
• DevOps Integration: Own and manage deployment workflows by writing Infrastructure as Code (IaC) and building automated CI/CD validation gates
• Data Management: Write optimized queries and design schemas for both relational databases (PostgreSQL, MySQL) and NoSQL stores (DynamoDB, MongoDB)
