• Disaster Recovery & Risk Control: Maintain contingency and disaster recovery plans, ensure storage and archiving integrity, and uphold strict compliance with Citi security standards and risk policies.

• Observability & Monitoring: Hands-on experience with modern monitoring and log analysis platforms (e.g., Kibana) to detect anomalies and trace transaction flows.
• Release & Version Control: Practical background participating in production release management cycles and utilizing source control tools like Bitbucket / Git.
• Incident & Problem Management: Demonstrated expertise handling high-pressured incident workflows, issue tracking, and formal Problem Management processes.
• Communication & Diplomacy: Exceptional verbal and written communication skills with the proven ability to translate complex technical concepts clearly to non-IT stakeholders and business users.
