Message

At Sphyrna | SRAM / Hammerhead, I manage customer cases involving Karoo devices, orders, shipping, and returns. I troubleshoot hardware and software issues, reproduce bugs, and analyze FIT files and ride logs before escalating problems with supporting evidence.

I also coordinate return and replacement workflows with warehouse teams, from checking eligibility and order details to arranging replacements or refunds. I support and coach agents on difficult cases and contribute to internal documentation.

At Concentrix, I supported Logitech and Logitech G customers, investigated recurring product issues, and shared customer feedback with internal teams. Earlier, in Flipkart Seller Support, I processed product and variant listings to help consolidate catalog pages and improve inventory visibility.
