  • Manage secure data storage, encryption (in-transit and at-rest), and regular backups.
  • Conduct vulnerability assessments and penetration testing for cloud systems and APIs.

API Security & Integrations

  • Build secure APIs with strong authentication and authorization frameworks (OAuth2, JWT, API keys).
  • Harden APIs against threats like replay attacks, brute-force attempts, and implement rate-limiting.
  • Develop secure integrations with third-party platforms ensuring compliance and data protection.

Monitoring & Incident Response

  • Establish real-time monitoring and alert systems using AWS CloudWatch, ELK, or Splunk.
  • Develop and execute incident response plans for rapid detection and resolution of security events.
  • Support internal and external stakeholders with technical troubleshooting and infrastructure queries.
