Software Development Engineer II at VERIZON (2019-12 – 2022-10)

• Migrated legacy ATG-based 5G product services (mobile routers, new connections, cart workflows) to microservices architecture as part of a 2-engineer team supporting nationwide 5G customers.
• Built a Redis-based caching layer that reduced database calls by 60% and improved API response times from 800ms to 200ms for customer and representative-facing applications.
• Developed backend services exposing JSON-based APIs for 5G product catalog, cart management, and connection provisioning workflows.
• Designed centralized logging, monitoring, and operational metrics systems that surfaced top exceptions and failure patterns — enabling proactive issue identification and faster troubleshooting.
• Received Verizon SPOT Award (2021) for contributions to large-scale 5G service modernization and migration initiatives.
• Received Verizon SPOT Award (2020) for implementing monitoring and operational metrics solutions that improved production incident resolution.

Assistant System Engineer at TATA CONSULTANCY SERVICES (2018-07 – 2019-12)
