Java Software Developer @Walmart

Bentonville, AR, US

As a Backend Engineer at Walmart, I collaborated with product managers and cross-functional teams to design and deliver scalable, high-performance microservices and data-driven solutions. I developed REST and GraphQL APIs with advanced pagination, authentication, and activity logging via Kafka, ensuring seamless integration with UI and downstream systems. My work included building NRT (Near Real-Time) and ETL data pipelines using Scala, Spark, and GCP (Hive/BigQuery), along with automating workflows through Airflow.I focused on performance optimization (reducing API latency to under 200ms), secure service-to-service integrations using Google Cloud IAM, and proactive monitoring with Grafana and ELK dashboards. Additionally, I contributed to DevOps practices through Dockerized deployments on GCP Cloud Run while ensuring code quality with comprehensive unit tests and vulnerability remediation.Tech Stack: Java 11/17/19, Spring Boot, Spring Data, Hibernate, Kafka, GCP, Airflow, Docker, PostgreSQL, Hive, BigQuery, Grafana, Prometheus, ELK, Scala, Spark
