Message

At Best Buy, I integrated two proactive customer service notifications that deflected repair-status enquiries, saving an estimated $1.6M–$2.1M annually. I also built invoice-vault and a batch process to generate and backfill invoices for California compliance.

I led the rebuild of in-store appointment scheduling as technical lead, replacing a legacy system that timed out for customers with extensive repair histories. I also coordinated cross-team delivery across backend, GraphQL, and UI.

At Juniper Networks, I upgraded a legacy Java application from Java 8 to Java 21 and created a web application that reduced test and analysis initiation from a full day to a single click. Earlier, at Mahindra Comviva, I led a jQuery UI-to-React migration and implemented RESTful APIs for alert management.
