CI/CD & Deployment: Contribute to continuous integration and continuous delivery pipelines to streamline code deployment, testing, and release cycles for web applications.
Cloud Deployment: Deploy and maintain web applications and backend services in cloud environments (AWS and/or Azure), ensuring high availability, security, and cost efficiency.
Security & Compliance: Collaborate with the cybersecurity team to embed best practices into the development lifecycle, including secrets management, secure API design, vulnerability scanning, and compliance automation.
