L2/L3 Technical Support Engineer specializing in SQL-driven root cause analysis and SaaS/integration troubleshooting for international teams.

What I'm looking for

I’m looking for an L2/L3 support role where I can own complex SaaS and enterprise issues end-to-end—using SQL/log analysis for root cause, handle integration/payment troubleshooting, and partner with product/engineering while communicating clearly with clients.

I’m an L2/L3 Technical Support Engineer with 5 years of experience owning complex support cases across SaaS products and enterprise retail environments, working with international clients and teams.

I combine technical investigation with clear client communication, using SQL-based root cause analysis and log analysis to drive fast, accurate resolutions. I’m especially effective at integration and payment troubleshooting when the issue spans multiple systems.

At TaxDome, I took ownership of 600 customer-reported cases, maintained 86% overall CSAT, and finished the final month at 100%. I investigated issues across web, desktop, and mobile apps using AWS logs, database records, and internal tools, and reproduced complex cases to compare expected vs. actual behavior.

Previously at Weigandt Consulting, I supported a 2,500-store retail group across production and test/UAT environments, investigating incidents through logs, integration flows, scheduled jobs, and database records validated with SQL. I also troubleshot Oracle products and Microsoft SQL Server/SSIS/Windows Server environments, and designed communication training for a 10-person support team to improve client-facing responses.
