Walmart Global Tech - the technology powerhouse for Walmart
• Spearheaded CI/CD pipeline automation of microservices using Jenkins, adding stages for code quality checks
using SonarQube to achieve 85% test coverage in all critical services, reducing code debt.
• Core Developer responsible for the performance and architecture of 3 high-traffic services serving 60M+ daily re
quests: Kafka-based inventory injection service, File-based feed injection service, and ATG Aux server.
• Spearheaded technology migration from Tibco BW to Java, achieving a tenfold speed increase (20→200+ tps)
and significantly reducing annual Tibco BW licensing costs.
• Engineered performance improvements by identifying and fixing bottlenecks in the legacy system, implementing a
Kafka-based solution that cut inventory processing time from 10 minutes to 2 minutes.
