Home Depot, Atlanta, GA
Senior Software Development Engineer
Jul 2021 – current
Description:
At Home Depot, I served as a Senior Software Development Engineer and played a key role in scaling
and optimizing the company’s e-commerce platform, homedepot.com. I developed and optimized critical
backend microservices using Java, Spring Boot, and Spring Cloud to support core business workflows
including user registration, product catalog, and order processing. I implemented performance
improvements that increased system throughput and reduced API latency by over 30%, ensuring
seamless service for millions of users. I also integrated Apache Kafka for real-time event streaming,
Cassandra for high-throughput data ingestion. My work directly contributed to improving
personalization features, system reliability, and deployment efficiency in a fast-paced, high-volume
production environment.
Responsibilities:
• Developed and maintained modular microservices using Java, Spring Boot, and Spring Cloud,
supporting core workflows such as user registration, product catalog management, and order
processing.
• Deployed and managed microservices on AWS using EC2, S3, and Lambda; leveraged SNS for
event-driven notifications and CloudWatch for centralized logging and monitoring, ensuring high
availability and observability across distributed services.
• Implemented a JWT-based authentication system with Spring Security, enabling secure, role-
based access and reducing unauthorized access incidents.
• Built real-time user activity tracking using Apache Kafka, capturing user browsing behavior to
support targeted product recommendations and marketing strategies.
• Used MySQL for structured data storage (users, orders, products) and Cassandra for high-
throughput writes (user events and reviews), increasing writing efficiency and supporting
analytical use cases.
• Integrated Redis caching for frequently accessed product data, decreasing average API response
times by approximately 35%.
• Managed service discovery and request routing with Eureka and Spring Cloud Gateway,
ensuring efficient inter-service communication and failover support.
• Contributed to CI/CD pipeline automation using Jenkins and Docker, significantly reducing
deployment time and increasing reliability across environments.
• Containerized services with Docker to ensure consistency across development, staging, and
production environments.
• Wrote and maintained unit and integration tests using JUnit and Mockito, achieving over 90%
test coverage and helping minimize production defects.
• Contributed to front-end enhancements using HTML, CSS, JavaScript, and React, supporting
responsive design and interactive features.
• Collaborated closely with cross-functional teams including QA, UI/UX, and DevOps within Agile
sprints to deliver timely and high-quality features.
• Participated in code reviews and knowledge sharing sessions, promoting clean code practices,
RESTful API standards, and robust error handling.
