• Produce monthly reports to track support KPIs and service performance over time.
• Develop and maintain documentation, including support processes, troubleshooting guides, FAQs, and knowledge articles.
• Contribute to a culture of continuous improvement, internal knowledge sharing, and operational excellence.
• Build and maintain strong client relationships, ensuring high customer satisfaction.

• Ability to clearly articulate technical concepts to non-technical stakeholders.
• Self-motivated, able to work independently or as part of a team.
• Strong client-focus and a commitment to delivering world-class support.
• Professional, friendly, and highly detail-oriented.
