PROFESSIONAL EXPERIENCE

Walmart Global Tech - New Jersey, US

Software Engineer Aug 2025 – Present

Built and enhanced backend services for Walmart’s Location Services platform, a critical system powering store selection, delivery eligibility, and omnichannel checkout experiences across millions of customers.

Designed and enhanced Java Spring Boot microservices responsible for customer location resolution, store eligibility,

and delivery commitment workflows across Walmart’s checkout ecosystem.

Contributed to system design discussions defining service boundaries, API contracts, and request flow between Cart,

Checkout, Account, and Location Services microservices.

Designed and maintained high-availability REST APIs supporting large-scale customer traffic while ensuring backward

compatibility and safe deployment strategies.

Improved reliability by separating stateful preference storage from stateless request processing, preventing temporary

store selection logic from affecting long-term customer location preferences.

Helped implement TPS-based autoscaling strategies in Kubernetes, ensuring stable service performance during peak

shopping traffic.

Collaborated with SRE teams to improve service observability and resiliency, leveraging Grafana dashboards, structured logging, and alerting to reduce incident resolution time.

Participated in architecture reviews and incident retrospectives, identifying bottlenecks in address validation and location lookup services.

Strengthened automated test coverage using Karate and JUnit, improving regression detection for critical checkout and delivery flows.

Participated in on-call rotations, triaging latency and error-rate alerts affecting location and address resolution services.
