At OnceHub Technologies, I provide advanced support for a global SaaS scheduling platform, resolving 75+ Tier 1 and 30+ Tier 2 tickets weekly while maintaining a 98% CSAT rating. I also personally own 25+ escalated technical cases each week from investigation through resolution.

I troubleshoot REST APIs, OAuth authentication, webhook failures, HTTP response codes, JSON payloads, and web application issues using Postman, SQL, browser developer tools, and internal records. I investigate integrations across Microsoft 365, Google Workspace, Exchange Online, CRM platforms, Zoom, Google Meet, Zapier, Make.com, and n8n.

Previously at iEnergizer Services, I served for 12 years as the primary escalation SME for complex technical issues across digital gaming and subscription platforms. I coordinated high-volume support during product launches, maintained SLA compliance, and earned the Best Consultant Award for four consecutive years.

I build practical workflow automations, write Google Apps Script tools, and create SOPs, troubleshooting guides, knowledge-base articles, and technical playbooks. I enjoy turning recurring technical issues into clearer processes and scalable customer support resources.
