Technical Support Engineer at Amazon resolving about 1,000 weekly data-integrity tickets and tracing catalogue issues with SQL.

India

Message

At Amazon, I resolve approximately 1,000 escalated data-integrity tickets weekly in the SIM/TT portal, maintaining 90–95% SLA compliance. I trace causes behind incorrect product attributes and use complex SQL queries to investigate and correct catalogue discrepancies.

At Salesian College, I engineered and maintained backend infrastructure for a college-wide ERP system supporting 5,000+ students and staff. I also implemented OAuth/JWT authentication and role-based access control, and reduced repeat support requests through staff training and reference guides.

Previously, at Infosys, I delivered an ASP.NET Core MVC shopping application and developed RESTful APIs for product management, authentication, and order processing. At Saint-Gobain, I shipped the backend for a customer-service chatbot that resolved 95% of inquiries automatically.
